concentric and radial elements are penetrated by numerous circular holes which are distributed
almost without order. The illterlamillal space, thus divided by the radial partitions into mOre or

Discovery of Ci?'copo?'ella semiclathrata HAYA,SAKA from Hokkaido.
(Resume)f

By
Hisakat su YABE and Tosio SUGIYAMAThe Hydrozoan coral, Oircopo"rella semiclathrata HAYASAKA is a rather rare, yet very characteristic
fos!:il in the Torinosu limestone developed in the Outer zone of South·West Japan, and in the Kwanto and Abukuma Mountainlands of North-East Japan. Very recently it was unexpectedly discovered
in a dark gray limestone ·i ntercalated in a complex chi~fly of schistose schalstein exposed a t the eastbank of the Saru-gawa, about 1.7 km east of Sinuit6 Mine in Horosari-mUl"a, Saru-gun, Hokkaid6.
Although only a fragmental one, th e present material exhibits features 'c haracteristic of the coeno·
steum of Circoporella sem'iclathrata as described by rL~YA~AKA; it occurred at the locality cited inassociation with such fossils as Ner'irlea (s.s.), Tlw.mna8trea an '1 other hexacoJ'als. As fully stated
n t.he Japanese text, t,his species is an important key-fossil of the Upper Jurassic not only in Japlln.
but also in abroad.
Oircoporella is very similar to Sphaeractinia in having the coenosteum composed of concentricla mellae and vertical elements, the conccntric lamellae being apparently two layered under highmagnificat.ion, a thin film-like layer lim iting the upper surface of a thick inner lying homoge neous
substance. and having astorhizae though rarely. TIJis genus was sometimes confounded with Burgtmdia MlF.NIER-CH,~LMAS, a stromatoporoid closely allied to Clathrodictyon and which possess coenosteum composed of trabeculae in vertical aorl horizontal sets, which are homogeneous in microstructure
under high magnification; further astorhizae are lacking to it and zooidal tubes ar e present.
In the renewed examination, the writers a re now confident in regarding Burgunclia anr! Oircoporella
to be generically independent, on account of the differences mentioned above, and the species of
Burgurld'ia of European writer (Burgumi-ia cf. sem'iclathrata HAYASAKA from th~ Astartian of Villereversure, Ain, France) to be true Oircoporella and not Burgund·ia .
. By way it may be pointed out that the Upper Jurassic marine deposits are divisible into threedifferent types according to lithological and foS!:il contents, namely: 1) Torinosn type composed ofshale and sandstone in alternation wi:h lenSfs of li mestone known under the name Torinosu limestone and often richly coralline, 2) Kitakami \,ype of shale and sandstone and lacking limestone, and3) Hokkaid6 type having considerable amount of schalstein "i~h limestone lenses which contains at.
least Oircoporella found in the Torinosu type.

On a Species of /so.gramma (Brachiopoda) from Manchoukuo*
I

By
Kotora M. HATA! and-Tatuo OMURA
Institute of Ge'o logy and Palaeontology, T6hoku Imperial University, Sendai, J apan.
(Read and received October 12 th, 1940)

The genus Isogmmma of the I sogrammidae was first establish ed by F. B.
MEEK and A. H. WORTHEN in 1870, based upon Chonrtes m'illepunctata MEEK and
WORTHEN. The generic diagnosis presented by C. O. DUNBAR and G. E. CONDRA:
is as follows ':"Concavo-convex or plano-convex shells of transverSely semi elliptical outline. The g reatest wid! his a little in front of the hinge-line and the cardinal extremities are normally ·a little rounded. The
width is much greater than ·the length of the sbell. The ventral valve is very gently convex andthe dorsal gently concave or plane, the general form of the shell closely resembling that of a largetransverse Chonetes, 'with the exception than in I sogramma the cardinal areas are obsolete or very
narrow.
Internally the ventral valve possesses a 'narrow but elongate triangular muscle pl'atiorm.
This structure stands a little above the level of the fioor of the valve, has abruptly truncated sides
awl a surface that is nearly fiat or depressed toward the mid-line.. There is no foramen or deltidilllUand probably there ar e no hinge-teeth . The dorsa l valve bears a small cardinal process whose baseis cont,inupd forward as a low, narrow ridge to about the mid-length of the shell Obscure traces ofpallial sinuses radiate from the beak over most of the in terior of this valve.
The surface of the shell is marked by fine, sharply elevated, concentric line, separated by broa~ler,fiat interspaces. The shell substance is moderately thick. According to BARROlS and PAECKELMANN,
there is an imperforate epidermal layer. The rest of the shell, however, is ablln 'lantly perforated
with coarse, simple, tubular pllnctae, which open internally and in the fORsil are commonly filld withmatrix ".

According to C. O. DUNBAR and G. E. CONDRA, "The name IsogmmmCl was
first introduced provisionally in 1870, in the following words which are found ina discussion of 'Chonetes? miUepunctata MEEK and HAYDEN'; ' should it befound, as we beleive it will, to be a new generic type, we would suggest for it
the name I sogmmma (i sos, equal; gmmma a line), in allL1 sion to the remarkableequality of the concentric lines of the surface'. The entire description of ' Chonetes?
millepunctata' was repeated verbatim by MEEK and WORTHEN in 1873 and bysome inadvertence, HALL and CLARKE (1894, p. 311) dated the genus from thelatter year and placed it in the synonymy of AulacorhynckL~s DITTMAR, 1872.
However, DITTMAR'S name was a homonym of Aulaco?'hynchus GOULD (1834) applied.to a genus of birds, and accordingly STRAND, in 1928, proposed a new name Aula-corhyncha for the brachiopod genus, while some~hat later in the same year SCHUCHERTand LEVEN.E (1929 B, p. 119) revived MEEK and, 'VORTHEN'S name Isogmmma. It
appears cl~ar that the .latter name was acceptable and PAECKELMANN, in 193Q (p_210), accepted th e name Isog1'amma and correctly dated it as of 1870.

Kotora M. HAT AI and Tatuo OMURA

Under the circumstances it appears best to r eject the name of AulacorhynchusDITTMAR, 1872, for this particular type of brachiopod with concentric sculpture,_
and to use the name of Isogmmma MEEK and WORTHEN, 1870, as clearly pointed, out by C.O. DUNBAR and G. E . CONDRAl ) .
The genu s Isogmmma, under the name of Au laco?'hynchus has been reported
by A. ,V. GRABAU and Y. T . CHAd) from the Carboniferou s rocks of China.
Theil' species, paotechowen sis, which is now refered to the genus Isog?wmma, wasreported to occur from the K uantikou limestone, east of Taiynan and in the
Miaokou limestone at Maoerhkou, west of Taiyuan in Shansi; in the Paotechow
limestone at P aotohsien in West Shansi, and also in the Houkou limestone of
the Lincheng coal-field in South Chihli. It is also said to be widely distributed
III the Taiyuan series of North China.
The wide distribution of this species has lead A. W. GRABAU and .Y. T. CHAO ·to stat e that, The species is therefore to be r egarded as a characteristic species in
the Upper Carboniferous division of the Coal-bearing formation in North China.
I sogm mma davi d~ on i (BARROIS) and L germanica (PAECKELhlANN) are known
from the Lower Carbonifer ous, 1. mi llep1mctata (MEEK and WORTHEN) occurs at
various horizons throug hout the Pennsylvanian System, "Ohonetes" concentr'i cus
D1B KONINCK occurs from the Carboniferous limestone in Scotland, and J. H ALL
and J. M. CLARKE3) state that, " species of this genus are not common, but appear
to be widely distributed in Cai'boniferous countries, Russia, Silesia, Scotland, and
the Asturias." C. O. DUNBAR and G. E . CONDRA Eay that DITTMAR has described
three species from the Permian rocks of Russia.
Thus it may be safe to r egard the genus as being confined to the Carboni·ferous a nd Permian in r ange.
.
Thfl specimens dealt with in this article were given to ·the senior writer for examination by Dr. Motoki E GUCHI, formerly of our Institute and now Professorof the Department of Geology, Kitirin College in Mai1choukuo. According to him,
the specimens wer e derived from a shale band, hitherto known as being unfoossilifer ous, at Nisiyama, Honkeiko, Honkei-ken, Hoten province, Manchoukuo.
Besides the brachiopod, there were also found several molluscs in association, thesewill be dealt with in another opportunity. The isogrammid brachiopod is evidentlynew to science, and to it is given the following description .

This new species is distinguishable from Isogmmma

size of shell, ' slightly broader concentric ridges on thesurface and by the sculpture becoming more simple on

in the Shansi District, North Ohina.

Yanosuke OTUKAIn this short paper, the writer describes the results of his stratigraphic observations in 1939 inNorth China. The Eastern Hill of Taiyuan-fu in the Shansi district stratigraphically consists, in descending order. of the redeposited loess, the loess Uhe Malan stage), the sand and gravel form ation(the Sanmeni an stage), (;he purple at· reddish chochol ate sandston e (the Permo-Triassic), t,he ligh t
br own sandston e, the N europter'is-bearing shale (the Permo-Carboniferous), the limestone, the Chonetes
carboni/era-hearing black shale (Middle Oarboniferous), th e alternation of black shale and sandstone •.
the basal conglomerate with iron nodul es, and the Oambro-Ordovician limestone.
As may be seen from a comparison of the stratigraphic columns established by NORIN and otherauthors in ·the Western Hill of Taiyuan-fu aM the Sbibhotze valley 'lVith the writer 's, it is likelythat some Permian and Oarboniferous stratigraphic facies in the former lack in tbe latter.

Tertiary Fo raminifera from the K(Jguti Formationand the Osawa Limestone in the Niitu
Oil Field, Niigata Prefect~re'*By
Tuneteru OINOMIKADO(Read Febrnary 24th; received October 20th , 1940)

Material from two localities was examined for the Foraminifera. One of themis fine sand of the Koguti Formation exposed near Kanatu, KalJatu-muri,l., Nakakanbara-gulJ, the other is loose fi~e 8and lense in the impure limestone at asawa,
akanbara-mura, Nakalianbara-gun. The Foraminifera fauna of the two localities
is relatively poor in number of species, but rich in number of individuals. The
total number of the species now distinguished amounts to 48; of them 32 are
fou nd at Kanatu; 34, including 1 new species, at a sawa.
The de term~ned species are as follows:

Tertiary Foraminifera from ,the Koguti Formation aud the Osawa Limestone87'almost" truncate, sculptured with lo~gitudinal costae; chambers comparatively few, iucreasing
rapidly in height and size as added" run:ni~g back obliquely on ,th,e outer border; ' sutures
distinct, limbate; wall Qrnamented with a few longitudinal costae; aperture terminal, broadly
elIiptical.

Dimentions: Holotype, Length 0,6~ mm., BreadtJi 0,33 'mm., Thickness 0,16 mm.
This peculiar, quad-rate form is easily distinguished from any other species,
In front view this species resembles somewhat Loxostoma amygdalaeforme (BRADY),
but differs fror;n the latter by its trunca,t ed periphery, more distinct and limbate
sutures, and few costae on the surface.
Type locality: In a loose fine ~and 'lense in the impure limestone at Osawa ,quarry, ()kanbara-mura, Nakakanbara-gu n, Niigata-ken (Pliocene).

The species from the first locality are Pseudoschwage1'ina .<chellwieni . (Y ABE)
HANZAWA, Schwagedna 1'egulari1ls (SCHELLWIEN), Schwage?'ina, sp. and Pusulina
sp.· The specimens were collected from the r~ck slabs of the quarry of Kit;lSyo~z'anof AkaEaka, -3, famous fossil locality of the Tifibu System, Rnd thei.r exact geolqgical horizon was not ascertained; but judging from the fossil evid€11CO their horizon
probably corresponds to (~ither the BeElizima .zonel ) or ' the lower horizon of t.he
AkaEaka limestone.
.
The species from the second locality are Pseudosch1lJage1'ina schellwieni (Y A BE)
HANZA,WA .and Schwage1'ina sp. The geology of this dist~ict was-- inv:estigated by 'T. TAKEYAMA2) and T. SEKI3) . Tho h?rizon of the : present fossils corre8ponds to.
the Samegai group of the Psendoschwagerina and Paraschwage1'ina zone of SEKI. .
According to SEKI, the fossils of this group are as follows:
Paras.chwagenna ohlo'ltga (OZAWA), SI,h wagerin'a n. sp. (S. kmffH group), Psru:dosehwug c1'in(isp:, ' S chwager·i lla vall/a,ris (SCHELLEWIEN), Sch1vageri,lla ((.l/Clersson·i (SCIIELLWIEN), Dnlioli111!
(£lriae DEPRAT.

The species from the third locality are Pswdoschwagerina samegaiensis sp. nov.
The' geology of this district· was studied by K. TAKiMoTo4). The horizon of thepresent fOSRil corresponds to (B) the middle of the Ryosen group of TAKIMOTO,
consisting main.Jy of f'chah;tein. According to TAKIMOTO, this group yields thefollowing fossils:
Schwagerlna vull/a1··i s (SCHEL~WIEN), S. vu.lgaris val'. l/lobosa (SCHELLWIEN), S. 1:J1'isc"a(DEPRAT), S. satni (OZAWA), S. pris('. fl. val". parumula (SCHELLWIEN), S . .,..i r.hthofe ni (BCHWAGER),
Mizzia velebitana SCHUBERT.

The grnlls Pse~~dosch1IJagerina which is often accompanied by the genur;
Pa1'aschwage1'ina is stratigraphically much confined in its occnrronce and accrpted
as an itnportant index-fossil of the baf'al Permian, such as the Sakmaiian of Russia
and the Wolfcampian of North America. From this it is inferred ·that the aboveenumerated three Pse1~dosch~lJa!Jerina beds are probably of the same horizon andeo;respond to the Sakmarian or Wolfcampian Stage.
orThough the Pse'ttdoschwagerina zone which produ.ces not only Pseudosclwagerina but also many Trtticites 'and Schwage1'ina, has so far been believed in Japanand the Eastern Asia to belong to the Uralian or the upper Carboniferous in age,
the writer call not contradict ~hat the Pseudo8chwag61'ina zone of Jllpan associates·the Uralian (new sense) or Pensylvanian fauna. - So that it demands deliberation
to believe that the Pseudoschwagerina. zone of Japan corresponds to the Sakmarian

GmnVnospir££ n. geD~
Type: Geminosp·ira simaensis n . sp.
Test obscurely rotaliform, turre~ed, unequally compressed laterally; chai:nbers incompletely biserial, inner chambers smaller and less in' number than outer chambers; distal wall inflated, with agroove on the ventral side; aperture narrow, on inner border near suture; wall calcareous, finely
perforate.

Gmninospira sirnaensis n. sp.
Test elongate oval, dorso-ventrally compressed, dorsal side fiatly convex, ventral side more convex,
periphery rounded; early chambers of microspheric form compactly coiled as in Rotalia, later uncoiled forming arcuate adult part, chambers in two rows, 8 to 11 outer chambers and 6 'to 8 innerchambers, inner chambers smaller; lunate in Cl'OSS section, a little embracing dorsal inflation of outer-chamber; a few early inner chambers invisible from ventral side; sutures not much depressed, early-outer sutures feebly limbate, early inner sutures slightly apressed; distal wall inflate, furnished witha groove on its ventral slope and just in front of the median suture extending in spiral direction;
apertural slit on the inside border of the last outer chamber along the suture with the last innerchamber, not extending below the groove. Holotype: length, 0.52 mm., width, 0.24 mm. A paratype:
length, 0.45 mm., . thickness, 0.14 mm.
This species is apparently in relation with Bttlim'ina eonvoluta WILLIAMSON, 1858 which seem tobe another species of Gem·inospira. GeminoRpira eonl:oluta from Torres Strait figured by BRADY shows
oblique outer sutures and a zigzag median suture unlike t.be present n ew species. Moreover it differsfrom the latter in having more strongly coiled test and much wider inrie r .chambers. In some specimens of Geminospira simaensis, the inner chambers are elongate and oblique to the median sutur e. It
is not certain that this genus is allied with Buliminidre, but it seems to have something common
with Caneris and Bagg·ina.
.

OoZiteZZn n. gen.
Type: Oolitella irregularis n. sp.
Test irregular, chambers usualy inflated, variable in form and sizE', without regular arrangement,
first chamber tubular; wall thin, very finely perforate; aperture circular with an internal tube, freeat the inner end. .

OoZiteZZa i1'1" e(J7~la1'is n. Bp.
_ Test very variable without a definite form; chambers up to 7, irregularly ovoid, not in spiral or
linear arrangement, addition of a new chamber taking place upon any part of the earlier chamber;suture sometimes con~tricted; first chamber tubular, smaller than the rest; wall thin very fine ly
perforate; aperture entosolenian; maximum long axis of chamber, 0.35 mm.
This very special form the Pieistocene of Sima is quite new to our knowledge. It is like .Adherentina SPANDEL, 1909 and Cayeuxina GALLOWAY, 1933 in outline, but it is c lear that they a re notin relation. The young examples have some common characters with Entosolenia VVILLIAMSON, 1858,
such as in substance, fine perforation, aperture and inte rior tube . . Monothalamous Entosolenia is said
to be a later form of the complex phyletic lineR of Buliminidre. Oolit ~lla may be a form a step later
than Entosolen'ia, in whic'h the early way of chamber arrangement has been missed.

On the Tertiary Platan168 from Hokkaido and Karah t:~o _(Preliminary Report)(ReSUllle)

By
Sahuro 6IS~I and Kazue HUZIOKA
Mere than 40 species (ef which six are living) of Platanus are knewn in the werld, t.he eldest.
knewn being the Cretaceeus. They may tentatively be divided into. feur greups in respect to the-- 41 --

353

foliar characters: (1) R acemosa group, leaf deeply lobate, (2) A cero'irles-occidentali§-oriev,talis group,
leaf shallowly lobate, (3) Guillelmae group,. leaf not lobate or obsoletely lobate, and (4) Basilobara
group, leaf peltate. Of these groups, the foliar characters between.(2) and (3) .appear to merge gradu ally
from one to another in many cases.
. Among the Tertiary plants of 'H okkaido and Karahuto the present authors discriminated six differen t types as fo !lows :P. ace'roids G OEPP.
lsika rian Stage (Palaeogene).
Hokkaido : Wood wardia Sandstone of Central Hokkaido ;Uryu coal-bearing beds of the UrJu coal-field.
Karahuto: Naibuti coal-bearing beds.
Urahoroian Stage (Ol igocene-Miocene).
Hokkaido: Sya knbetu coal-bearing beds of eastern Hokkaido.
P. Guillelmae GOEPP.
I sikarian Stage.
Hokkaido : vVoodwardia Sandstone.
Karahn to: Naibnti coal-bearing beds.
Urahoroian Stage.
Syakubetu coal-bearing beds in eastern Hokkaido.
Kawabataian Stage lMiocene).
Hokkaido : K ayanumli. coal- bearing beds of the Kunnui Series in southwestern Hokkaido(as cfr. P. Guillelmae).
Cfr. P. aceroides lat'l!ol-ia KNOWLT.
I sikariall Stage .
vVoodwardia Sandstone of Central Hokkaido.
P. Mabuti-i sp. nov.
Ul'ahoroiall Stage (Syakubetu coal-bearing beds),
P. sachal'inens'is E Nno.
I sikarian Stage (Naibuti coal-bearing beds of Karahuto).
P. Hm'i L ESQ.
Cretaceous (near Due coal mine, Russian Karahuto).
P. aceroirle& and P. Gttillelmae are common and occur in association in most cases: Cfr. 'P. Gttillelmae
occurs from the Neogene beds of the Kayanuma coal mine, and this is the y'o ungest record of fossil
Platanus in the Asiatic continent (the authors recently I'ecognized 'another Neogene Platanus from theEnge: hal'd t-i a~bed of Tyosell). P. },o[abut·i-i and P. sachalinensis are characterised hy having pelta te
blade. Ofr. P. a.cel'oides latijolia te3embles the original specimen but is somewhat imperfect t.o admit
precise cOlllparis~)IJ . P. EIeeri has been recorded only from the Russian K arabn to but not known from
-Japan.
In Hokkaido and Karahuto the development of Platanu s began from the Cretaceous and it flourisherl most. in th e Palaeogene. It maY be certain that it existed also in the early Neogene, but
possibly disappeared since that time from these islanos.
T he details may be printed in . the J ournal of Faculty of Science, Hokkaido Imperial University.

On the Tertiary Marlea (= Alangium) from
Hokkaido and Karahuto.
(Preliminary Report)(Resume)By
SaburB OISHI and Kazuo HUZIOKA
There are -about eight living specicsl$llf ],[arlea (= Alangiu?l1.) distributing in Japan, Manchoukuo,
China, and palaeotropical r egion of southeastern Asia. Of these, ],[. platanifol-ia SIEB. and Zucco and M.
chinensis REHDER are living in the Japanese I slands, the northern most limit of the form er being Provo
Kitami (N.L. 45°) of Hokkaid6, while the latter the southern Kyusyu (N.L. 32°).
The authors recognized four different types of fossil ],[arlea from the T ertiary rocks of Hokkaido_:and Karahuto. They are ],f. bwritruncata sp. nov., ],f. kusiroens-:s sp. nov., ],[. taiheiensis sp. nov.
and ],[. basiobligl,a sp. nov. The former three are the type of modern ],{. riatani/olia, while the last-one is the type similar to ],[. chin ensis. ],[. basitruncata and ],{. basiobliglta have been derived fromthe Woodwardia Sandstone of the Isikari Series of Hokkaid6 (lsikarian Stage; Palaeogene), M.
ktlsiroensis from the Syakubetu coal-beariug be-ls of the Urahoro Series of Hokkaid6 (UrahorianStage; Oligocene-Miocene) and ],[. ta'ihe'iensis from the Esutoru coal-bearing beds of Karahuto{Kawabataian Stage; Miocene}.
In 1939, KRYSHTOFOVICH and BORSUK brought Ficus tiliaejol·i a (AI BR.) HEER and Biittneria ae.qualijolia (GoEPP.) MEYER into one species and adopted the generic name A.langil.£m taking the latter
specific name. The present authors agree with these Russian authors in that the genus Almigiltm(=],[arlea) is the more adequate generic designation for the named fossil types, yet the present
authors bear a different opinion in bringing them into one specific type. Types referable to "Bi1ttneria aequalijolia" are rather common in the Kawabataian flora of Hokkaido and Karahuto, but thecompar-ison with the living types bearing similar foliar characters is now carrying on.

are a few records of some pygidia. provisionally identified to Phillipisa1 ) (sens.ext.)I-found in the Permian Maiya series of the southern Kitakami Mountainland and 'the contemporaneous deposits of the Abukuma Mountainland. The palaeontologica,I.~nd stratigraphical works by the former and present members of the Institute of'Geology and Palaeontology, Tohoku Imperi'al University in the southern Kitakami
Mountainland, have recently greatly extended the geological distribution of trilobit es, and their r emains are now known from at least four other different horizons,Kawauti, Nakazato, Omori, and Tyoanzi series . . In the upper part of the Omori;series trilobite-remains are particularly abundant and some of them are fairly wellpreserved.
The present material was collected a few years ago by the senior author during
his fi~ld work in the southern Kitakami Mountainland, from the Nakazato series,
tho precise locality being tho south-west slope of Takainari-yama in the K esen.district,Iwate-ken. It consists of an incomplete cephalon and a left eye both belonging, without doubt, to t.he same species and bearing features the characteristic of
the genus Phacops (s. s.) which has been establish ed by H . F. EMMRICH2 ) in 1839
,on Phacops latij?'ons BRONGNIART from the Devonian of Bohemia.
Phacops (s. s.) is a characteristic trilobite of the Devonian and upper Go tlan·dian and more than 40 species have been recorded from the world, in so far as
known from the literature consulted. Many species of this genus are from Europe:and North America, while only a few being known from the southern h emisphere.
During the thirty years past, this genus haS' been repeatedly revi~wed by F . R. C.
REED3>, ~. \VEDEKIND4), RUDOLPH and Emma RICHTER5), D. M. DELd>, and others,.and its generic status was made clear by the thorouth revisions by RICHTER in
1926, REED in 1927, and DELO in 1935. The Asiatic species of Phacops (s. s.).are shown in the table 2.
As shown in the table ~, all the known species occur' from the Devonian. The
Nakazato series from which the Japenese material now at hand has been derived
is also Devonian in age, and the occurrence of the genus in Japan is the first.record and is particularly interesting from the view of its geographical distribution in the world.

As stated above, the present materia-} is characterised by having large schizochroal eyes, and tubercurated glabella with very indistinct lateral furrow6; all thesefeatures are marked serving to remove its alliance from genera such as Reedopsis,.
Eoc?·yphops, Cryphops, T1·ime1·ocephalus, NepManops, Dianops, Bm~leia and othersin the Phacopinae_ In having large schiz'ochroal eyes, it considerably approaches
Dalmanites, but the latter has the glabella with distinct lateral furrows. Of theabundant species of Plwcops (s. s.), Phacops latif1·ons, the type of the genus, bears
many characters in common with the Japan ese form, but the latter is easily distinguiEhable from the former by having a large number of lenses in the eye:::. In
latij?-ons, the lenses are arranged in rows numbering up to 18, and amount ingeneral to 77-90, at most 120 in the total number, while in the Japanese material
there are 157 lenses arranged in 17 rows. In trilobites, however, the number of-49 -On the Discovery of Phacops (s. s.) from the Nakazato Series of the Kitakami Mountainland36]

lem es in eyes is genera lly sai~ to show a considerabl e variation in different individll a ~s of the mme ~peci eR ; . 8f'pecially it is far less in the you'ng than in th e adult.
But as stated above, the differ ence. r ecognizable in the number of lenses of eyesb etween the JapeiJese material and lat'ijrons is too g reat to' be look upon as mere
variation within the same· species. The former is thGr ef0re perhaps referabl e to a
new form of Phacops (s. s.) closely allied to the latter. However, owing to thescanty and fragmental material, the er ectf0n of new specific name is at present
avoided.

Occurrence of the Kushan Trilobites in Northern Anhuiand a Note on the Rakuroan Complexof the Shankiangan Basin*
By
Teiichi KOBAYASHI(Received May 6 th; read May 24 th, 1941.)

1) Occur1'ence of the Kushan Trilobite in Anhui : -While studies on the,Cambrian stratigraphy and palaeontology are fairly well advanced in eastern North"
China, South Manchuria, Chosen and the border - ....-~-,..-..
land between South China and Indochina, ourknowledge is still meager in the remaining
parts of Eastern Asia, and in such territories
even sundry facts are worth noting. R ecently
Dr. T. TOKUDA of the Mitsui Mining Company
obt~ined a slab contaning a few trilobite fragments
at Chieu-Iung-kang, Huai-nan, AnhuilJ, and submitted it t~ me for study for which courtesy I am
deeply grateful. The slab is a gray earthy marl, •Fig, 3Fig, 1
the weathered surface of which is of yellowish
Fig.· 1. Bl.ackwel~ria monke·i x 2
colour, and contains three species of trilobites as
Fig. 2, Drepanura premesnili x 1

follows:
A pygidium of Blackwelde1'ia monkei (WALCOTT)
A free cheek of Drepanu1'a premesnili MONKE
A pygidium of Teinistion lansi (MONKE)
In the pygidium of the first species the first lateral spine is unusually long,.
extending postero-Iaterally but curved inward in the posterior portion, but otherwise
all the features are typical of the species. It somewhat resembles the pygidium.
of Drepanu1'a kettel81'i but the axis is much narrower and the anterior margin ismore rounded. The anterior position and the small size of the eye in the cheek .
of the second species suggest that it belongs to D1'epamwa p1'emesnili rather thanto D. kettele1'i. Its lateral rim is remarkably elevated and thickened in the an-. ·terior, and fine subparallel lines are found on it. Its cheek inside of the rim is .
smooth whereas this part is granUlated in D. ketteleri. As the genal portion is
not presserved, whether it has a genal spine cannot · exactly be determined. Fora detailed description of this species the reader is r eferred to a recent paper Of'* Transact,ions of the Palaeontological SOCiety of Japan, No. 127,1) ~l¥'d!j iff i¥i :fLfl! /Mf.

minel ). The pygidium of the third species is broad _and has a: narrow axis which
is elevated above the flat pleural lobes. Six pairs of flat spines are found on theborder among which the outermost one is the longest and the innermost the broadest. Judging from these features it best agrees with the pygidium which MONKE
referred to Teinistion lansi.
I.
All. of these fossils
arecharacteristic
menbersoftheKushanfauna and tho.
rock containing them shows an aspect typical of the so-called Kushap shale.
Therefore it is quite certain that the slab was obtained from the Kushan .formation
although. the Cambro-Ordovician succession of the Huai-nan district is unknown.
. 2) The Camb?'ian Fossil Zones in the Tingyuan-Fengyan Region: -The best
Cambrian succession' in the Northerb Anhui was determined iIi" the TingyuanF engyan (5E~ · M~) region by W. T. CHANG and C. LI, and its summary is given.
in GRABAU'S" Palaeozoic Formations in the Light of the Pulsation Theory, vol. 3"_
It consists of five formations and five fossil zones as follows:
V. Leechiachuan formation (105'm.)
IV. Miashan fOl'matien (150m.)
III. Dachiling red sandstone (4m.)
II.

Although I have not as yet seen CHANG'S palaeontological peper, it is cC'rtain
th&t the lowest formation belongs to the Shora stage as Redlichia is contained.
Ptychoparia tube?'wlata is a new specirs hq.t the zone containing ptychoparids
may be referred to the Shihchiao if not to the Tangshih stage. The next zoneyields Kootenia asiatica, K. punctata, K. anhwiensis, Emmerichella laevigata, andAiwmocarella rectang1data. Among them j(ootenia ptmctata is the species first·
described by myself2) from the OZenoides zone of Neietsu in South Chosen and a·
recent study on the geology of the Neietsu district by 1. YOSIMURA3) showed thatthe zone is located in the lower portion of his Machari formation. As noted alrea9-Y the fauna of the Ole'noides zone is intimately related to the Stephen faunain North America. Although WALCOTT4 ) correlated the Kushan with the Stephen'fauna the two faunas are in fact quite different. Likewise the Olenoides fauna ofSouth Chosen is certainly distinct from the Kushan one. In the upper part of theMachari formation there are the LopnO?'ites and Olem~8 zones but the Kushan
stage has not as yet been discovered. Although more study is needed beforewe ' can say anything definite on the matter, I am inclined to believe that

,certain that K ootenia asi&tica is a trilobitE) much older than K. p1mctata. I foundK. asiatica in a limestone boulEler in a hill north of Chuwa which is exclusively,
composed of Redlichia shales. Howeve.r, because the Kootenia zone is located above
the PtychiJpa1'ia t~tberculata zone in the section of Northern Anhui it may not be.
DIaer than Tangshih. The youngest in the section is t,h e Manmtyia, o?'ientalis zone
which belongs to the Taishan stage.
Unconformities are said to exist between the Heishiling ' and Shanchin formations a~d between the Dachiling and the Miashan ' farmations. Judging fromthese fosssil zones, however, time-gap between the Redlichia and Ptychoparia zones.
is not as great as that between the Kootenia and ]J{ansuyia zones where the fossil-zones of the Pais han and Kushan stages are missing. The stratigraphical break,however, ought to be determined not on~y . by fossils but by field-evidence, and the.finding of the three fossils above mentioned indicat~ that the Kushan stage isprespnt at -least' in the Huai-nan area in thrf same province.

"The quartzite formation overlies the Taishan complex and is 50-200 m. thick; the siliceous limestone exsists between the Taishan complex and the Cambrian strata but is only a very few to
90 m. thick."0· 'As to the southern extension of the Sinian System L12) states in Explanation
to Nanking-Kaifeng Sheet as follows:"The Sinian system rests unconformably upon tbe vVutai system and iucludes two parts between,
which tbere occurs a disconformity, the lower part being composed chiefly of qnartzite and the upper
part of limestone. In the Feng-yang (1PJ.1!lJ}) district, Anhuei, the lower part comprises reddish andwhite quartzites and amounts to about 150 m. in thickness, the upper part contains largely the lime.
's tone which is mostly converted through intense metamorphism into y~J1ow and white' marble, witha; thickness of from 120 m. up to more than 400 m. At Feng-huang-shan (JilA!MW./) in the Ling-pi (1t~district, the limestone becomes silicified and includes !liliceous bands or layers." And" the Huochiu(~lill), Shou·hsien (~J!I*-) and Meng·cheng (~:!!i!I;) districts, the lower part is composed of quartzite and:shaly sandstone and estimated at about 100 m . in thickness, the upper part of gray-green thinbedded
limesione with shale, with a thickness of less than 100 m. At Shunkeng-sban (~~JlJ) the lower partis missing and the upper part contains siliceo~s limestone and shale, amonnting to about 150 m. inthickness. In 1he Ssu-hsien (ifMJ!I*-) district, Anhuei, and Pei·hsien ('1i1i~) district, Kiangsu, only thelower part is found, comprisi'ng qnartzite with sandstone, sandy shale and shale. But in the Suei-ning(or Suin~ng D!E$) and Ling-pi districts and some part 9f the Ssu-hsien district occurs only the upper
part which contains siliceous limestone with thinbedded limestone and yellow shale. In the Yishui(jJj:7]() district, Shan-tung, the, lower part consists chiefly of white quartzite; white and reddieh sandstone, brown shaJy sandstone, red-brown and grey-green shale and conglomerate, with tbe total thickness<If form 20 to 50 m. In other parts of Shantung where the Sinian system occurs, only the upper part isfound and composed cbiefly of siliceous limestone with greenish and brown sha1t1s and sandstones, thethickness being from 10 to 50 m 3) ." ,. The distributio,n of the Sinian system is confined to the regions
north ot the Huai-yangshan (j!tIi~JlJ) Range. Owing to its having small thickness the system composes<only some low hills and in some places forms one part of the hills and mountains."

as Chengshan (:!Jitlll) and the upper limestone as Mianshan (*ftHl:J1. In the area
surveyed by them, 120 m. and 480 m. are the average thickness of tl'tt two series \respectively. Th~ Chengshan contains some hematite. They inclined to correlate
the Mianshan with the Tayang iimestone of Shansi or the Nankou limestoneof Chihli.
Judging from the observations so far gathered by various geologists, the\ Sinian system is widely distributed in the region but varies in thickness. It is

f-cally disappears. It is most probable that the I-chou series belong to the top
division of the Sinian, if not the basal part of the Cambrian system. The Mianshan
which is frequently siliceous, is Middle Sinian and the Chengshan, Lower Sinian.
In other words, the lower and middle divisions of the Sinian System are developedin the southern and central parts. The middle division probably merges upwardwith the upper in advancing from the central to the northern part of -the region:and farther to the north only the upper division is present, which thins out toward
the northeast.
5) Shankiang(tn Basin: -Judging from our existing knowledge the Sinian in
Northern Kiangsu and Northern Anhui belongs to the lower and middle divisions,but that in Western Sh?ntung may belong to the upper one: It is, thickest at
Fengy~g district but dies out toward the northern and eastern sides of the Western.
Shantung block. The Cambrian system is on the other hand thick in southernpart of Western Shantung where Lr estimated it to be 700 m. tliick but thins out
toward south. It is about 400 m. thick at Tangshan and about 300 m. thick at
F engshan, and abruptly decr:eases in thickness in the west side of Norther-n Anhui.
According to Lr the Cambrian is represented by several tens of meters of strata.at Kuoyang and Mengcheng. Similar change of thickness can be seen in thenortheaFitern border of "Western Shantung. The Cambrian formation generally
ranges from about 300 m. to 650 ffi. in thickness and 350 m. is the average thickn ess of the Ordovician formation in Western Shantung. But according to YA~1ANE
the . Cambro-Ordovician formations measure only about 140 m. in thickness in theeastern margin of the Western Shantung block.
The change of the thickness of the Sinian system shows that the are~ involving 'Western Shantung, Northern Kiangsu and Northern Anhui is a basin which
is separated from the Heinan-Kuantung geosyncline by a peninsula extending fromthe Keiki~land to Shantung. Therefore taking the first syllables of the three provinces the area is called the Shankiangan <rlJ1.L~) basin. Through the Sinian period
the outline of the basin shifted to the north till at length the center of ,the basinchange'cr- from Fengyan to I-chou. It is certain that the basin was closely connected with the geosyncline in the Cambro-Ordovician period and the physical condition was not so different as before . The Eastern Shantung bl0ck stood above
the water-level all the time except in its northeastern margin which, it is possible,
sub!3ided once in the Sinian period.
To the south of the Weiyanshan' range there is the Lunshan Olihij) limestone
containing the 'Volungian. fossils. It is 900 m. thick and is oyerlain by theTangshan U$.iUJ) shale and limestone formation, 30 to 40 m. thick, which yields,01·thoce1·as ch·inense. Above this there are the graptolite shales of the late Ordovician and early Gotlandianages, and the graptolite facies extends to the middle
and lowe~ parts ' of the Ordovician system -to the east and south of Nanking.
. Therefore it is certain that the Tsingling-Keijo line1lwhich is the Qrdovician geo-.

graphic boundary -of prime importance passed through the Weiyangshan range.,
The occurrence of the W olungian fossi~s in the Lumhan limestone shows that the
cephalopods could intermittently migrate through the boundary. The Lower Ordovician trilobite fauna i~ the Yangtze Valley is related to the Tomkol fauna in.
South Chosen on one side and to the Lower Ordovician ones in Burma and Indochina on the other. The rocks of the period in Chekiang and gther parts of theLower Yangtze Valley insofar as I caB judge from their description, are similar:
to those of the Tomkol series.
The reference of the ·formation below the Tomkol equivalent to the SinianI
system is merely a conjecture: The formation in question is characterized by inclusion of black carbonaceous shales which alternate with thin layers of calcareo,u s.
shale and limestone. This part of the formation appears to suggest that the Machariformation of S,outh Chosen is traceable to the west into the lower Yangtze Valley.
This suggestion is emphasized by the fact that Lopno1'ites whi~h is a characteristic
genus of trilobite .in the upper Machari formation is known to occur at Lan-hsi,.
Chen-chou-fu in the Province of Hunan, as reported in my previous paperl). Therefore, in my opinion, the formation adjacently below the Ordovician in the' lower
Yangtze Valley is more probably the Canibrian instead of the Sinian as consider edby Chinese geologists, and the faunas contaiued is expected to be similar to thoseof South Chosen and especially of the Neietsu district. In other words the W ei-.
yanshan may be a geographical boundary not only in the Ordovician but also in
the Cambrian period.

A New Naiad, Unio (Nippononaia) ryosekiana,
n. subgen. and n. sp., from the Lower
Cretdceous of Japan*
By

Koiti SUZUKI
Contribution from t,i le Geological Institute, Faculty of Science, Imperial University of Tokyo.
(Received May 20 th j ·read May 24 t.h., 1941.)i. Recently Prof. T. NAGAO submitted to the writeF two specimens f;)f an intere.stjng fossil naiad in his old coJlection for study. According to him, it is certainthat these specimens were collected by himself from the Ryoseki group which is
the .basal part of the Early Cretaceous Monobegawa' series, but its locality is uncertain whether it was Komo, Hanoura-mati, Naka-gun, Tokusima Prefecture, or,somewhere in the Santyu grauen in the Kwanto mo.pntainland. There are a large
mup-ber of fossils procured from various localities of the group in Japan and kept
in the Geological Institute, Imperial University of Tokyo, They are now placed.at the .writer's disposal for study, but none of these collections contain this species.
One of the two specimens which NAGAO sent to me is an internal mouldof a left valve wanting the posterior end. It clearly shows featUres of the hingeteeth which consist of two short, narrow pseudo-cardinal and two long, lamellar
and smooth lateral teeth, . Fine but distinct crenulation is fou'n d on the inner sideof the ventral margin. The otter specimen is an external mould of the left valveof a different individual. Its posterior and dorEal parts are not preserved, but thesurface is ornamented by numerous radiating ribs which cover the whole of ' thedisc.. Some of them converge to form a series of acute V in the middle of thedisc.
Judging from the outline and f@atures of the hinge, this shell may be referredto the genus Unio. Its surface ornament is, however, quite different from that-of Unio, resem~ling closely to the ornament of certain forms of .t he South American
genera, Diplodon, P1'isodon and some others, in the subfamily H yriinae, or of'l'rigonioides kodai1'ai KOBAYASHI and SUZUKI!), a trigonid from the Lower Creta-ceous formations of Tyosyn (Korea) and Manchouku0. No specimen of Unio has:such distinctly radiating and widely spr~ading ribs as in this she~l. Especially _the marked crenulation of the inn er side of the . ventral margin as ' in this shell is·entirely missing in Unio and is very rarely, though not at all, met with in the,subfamily Unioninae as a whole. _ By these reasons, a new subgenus is instituted
here in gell;us C!nio on the basis of a ' new speci es, U. (Nippononaia) ryosckiana.

The sl;lell of the ge'nus Par?'eysia1) possesses the hinge-teeth similar to those of
the present Japanese fossil shell and often the radiating orn~ment somewhat resembling that of this, but the former shell is generally much higher than the latter,
Moreover, the radial ornamep-t of Pa?'reysia is in the adult stage always confinedto the umbonal region and consists 'usually of criss cross or zig zag r-ibs, Having
the soft parts of the structure essentially of the North American genus Q'uadnda t .
Pa?·q·eysia is quite distinot from Unio, However, the conchological criteria of these
two genera are at present fairly obscure and it may not be easy to decide whether
the present new ,subgenus Nippononaia really belongs to the genus Unio or to
Pa7Teysia, Nevertheless the outline and dentition of Nippononaia appear to suggest
its closer affinities to Unio rather than to Pa?·?·eysia. The recent representatives.
of Pa?Teysia are widely distributed in India, Burma, southern China (?) and thetropical\ Africa, and the fossil ones are recorded from the Cenozoic formations inIndia and Burma.

Unio edwini GUPTA2) described from the younger Tertiary formations of Burma
has the surfac~ ornament of a nature fairly similar to that of Nippemonaia, Because it has an ovately subtrigonal outline and the radial ribs more or less broken
into granulation, it may probably be referred to the genus Pa?'?'eysia, though detailed
features of its dentition are not known and its subgenus or section in the genus.
is uncertain.
The writer wishes to acknowledge his indebtedness to Prof. Takumi NAGAO
of the Department of Geology aud Mineralogy, Hokkaido Imprrial University, who.
kindly gifted the specimens of this interesting shell to the writer, Thanks arealso due to Prof. Teiichi KOBAYASHI of the Geological Institute, Imperial Universityof Tokyo, for reading over the manuscript.

margin relatively short, sloping and very weakly arched. .Beak probably not high,placed at point about one-third of length of shell as measured from anterior extremity. Surface ornamented with many radiating ribs crossed by concentriclines of growth; radial ribs fine and closely set in middle of disc, but getting
distinct and widely spaced towards both ends, espe0ially backwards; several ribs in
middle converging to form acute Vs on a line through beak, and on each side ofthem about fifteen ribs not meeting; ribs on the antero-dor~al area fine and branching
off downwards from a line running from beak to antero-ventral margin; lines ofgrowth very fine, but closely set and elevated at irregular intervals, representing
succesive periods of growth. Hinge of left valve well developed; cardinal teeth 'relativly short, narrow and very finely crenated, the lower one stronger than upper;
lateral teeth long, lamellar, smooth, almost conglutinated into a broad tooth nearbeak, upper one much narrower than lower. Beak-cavity not deep. Inner side ofshell markedly crenulated on ventral margin, especially in posterior half.
Type specimens.--Holotype: Internal mould of a left valve wanting theposterior end (tex-fig. 1). Paratype: External mould of another left valve wanting
the dorsal and posterior parts (text-fig. 3). Both of these ty-pe specimens are kept
in the Geological Institute, FaCUlty of Science, Imperial University of Tokye.
Measurements.-The holotype specimen is about 33 mm. long and about 16 mm.
high.
Formation and locality.--Ryoseki group, the basal part of the Early Cretaceous
Monobegawa series; Komo, Hanoura-mati, Naka-gun, Tokusima Prefect~re,Santyu graben in the Kwanto mountainland.
Remarks.--The ornament of the postero-dorsal area can not well be observed.
As clearly shown on the small external mould of the holotypic left valve, thepresence of many fine and closely set radial ribs on the postero-dorsal marginal
surface suggests th·at the postero-dorEal area of this shell is marked by many
radial ribs either continued from those of the post.erior half of the disc or branched
off from the posterior ridge tQward the postero-dorsal margin .

Falbellum tran8versal~ MOSELEY, Acanthocyathu8 grayi MILNE-EDWARDS et HAUfE, Oitharocyathu8 CO°·nicus ALCOCK, Heterocyathu8 aequicostatus MILNE~EDWARDS et HAIME, Anthemiphylli a dentatus (ALCOCK), .

aff'. ret'iformis LAMARCK, Fungi(L sp. (broken fragment), Fungia sp. (Cyc~ oseris form), and F. aff'. patel-·li/ormis BOSCRMA. The last mentioned three are reef-building corals, and the others are all deep-sea .
coralil.
All except Trochocyathus (Thecocyathus) hanzawai YABE et EGUCHI are now living in the adjacentwaters of the Philippine Islands, and all except Acanthocyathus gray·i MILNE-EDWARDS et HAUfE,.
Acanthophyllia cf. dcshayesiana MICHELIN and H eteropsamm'ia 7I1 ichelinii MILNE-EDWARDS et HAIME are·represented in the RyOkyu limestone formation of Kikai-zima, Ryukyu Islands.
Acanthocyathus grayi, according to U~mGROVE is a synonym Acanthocyathus malayicus GERTH •.
however, from a study .of numerous specimens from the Pliocene deposits at T6nohama, Tosa Province, it is certain that the former is not a synony~ of the latter.
Details will be published at a later date.

On Two Species of Simple Corals from Kagosima-ken, Kyusyu*
By

Motoki EGUeRI
Contribution from the Sendai K6tOkogyo Gakk6, Sandai, Japan.
(Read and received May 24 tb, 1941.)

Recently S. ENDO of the Institute of Geology and Palaeontology, Tohoku Imperial University, during his collection of fossil plants from several localities near
the city of Kagosima, Kagosima-gun, Kyusyu, fortunately obtained some marine
fossils, among which were discovered two species of simple corals.
Here the writer wishes to record his thanks to Emeritus Prof. H. YABE of
the ' T6hoku Imperial University, Profs. R. AOKI and S. HANZAWA of the Instituteof Geology and Palaeontology, T6hoku Imperial University for kindly giving thewriter the opportunity to study the simple corals. Deep gratitude is offered to Dr.
K. TSURUMI, Dean of the Sendai K6t6kogyo Gakko, for giving the writer permis.sion to pUblish this article. Acknowledgements are also due to Mr. K. KUMAGAI for
taking the necessary ph~tographs.
Among the two corals, Deltocyathus o1'ientalis DUNCAN, is ' known to be living
jn the waters around Japan, ranging from Aomori-ken at the north to the East
Indies, Indian Ocean and Mediterranean ' Sea at the south and' at the west. As
fossil it is known from the Pliocene and Pleistocence of the K wanto . region ofCentral Japan, the Pliocene of Taiwan, Plio-Pleistocene of the Ryukyu Islands,.and fr~m the Upper Pliocene of Ceram. The Present record of this coral from
Unoki, Yosid,a -mura, Kagosima-gun; Kagosima-ken (Reg. No. 65019), is a new
Jocality.
Although Deltocyathtts 'o rientalis is represented by only two specimens in thematerial from Unoki, it is remarkably abundant ilf the Ryukyu limestone for.mation of Kikai-zima in the RyUkyu Islands, it is expected to occur in larger
numbers in the fossil layer at Unoki by future collection.
The other coral, Hete1'opsammia cf. ovalis SEMPER, which is from Kuwanomaru,
Yosida-mura, Kagosima-gun (Reg. No. 65018), is not very well preserved, and.although its generic position can be settled easily, its specific posit~on is rather
difficult owing to its being somewhat water-worn. Heteropsammia ovalis is known
to occur from the Younger Cenozoic rocks of Mindanao in the Philippine I slands,
Plio-Pleistocene of Ceram, Miocene of Java, Pliocene of Taiwan, Pliocene of Sikoku,
Pliocene of the Kwanto region of Central Japan, and from the Plio-Pleistocene-{)f the Ryukyu Islands. As known at present, there are no living records of thisin'teresting species.

However, Hete7'opsammia cochlea (SPENGlER), a r ecent coral from the Philippine
Islands in 25 fathoms, the East Indies in 15-83 m eter s, and . also from off SetoKanayama, Wakayama-ken in 46 meters and from off . Karatu, Saga-ken in 106
meters, is more or less similar to Heteropsammia
1
ovalis. Also very closely related to the doubtful
fo ssil from Kuwanomaru are H ete7'opsammia ovalis
jormosensis Y ABE and EGUCHl and H. ovalis
japonica Y ABE and EGUCRI, the former from the
Ryukyu limestone formation of Kikai-zima in
the Ryukyu I slands, and the latter from the
Byoritu beds of Taiwan. If the present fossil
were perfect, it appears that it might belong to
H. ovalis japonica. Heteropsammia was alsor ecorded by J. MAKIYAMA from the Pliocene
Sasage beds of Tiba-ken.

they are not known to occur ill association. The geological age' of the formermentioned formation is Plio-Pleistocene while that of the latter is Pliocene, tllU~
the geological r ange of Hete?'opsammia ovalis is from the Miocene (of Java) to theLower Pleistocene, while that of Deltocyathus o?'ientalis is from the Pliocene tor ecent.
Both of the mentioned simple corals are not sedentary forms but belong to·
the free type, and therefore are generally restricted to sandy bottoms or to thoseconsisting of fine material. Among the deep-sea corals the ones just mentioned.
belqng to the shallow water forms and inhabit a sea-bottom generally within thed epth of fifty meters, although there are still deeper r eco rds. Therefore, if a boldconclusion can be brought about, the writer believes that the_ shell-beds in which
the present corals were found may not have been laid q.own at a depth not exceeding some fifty meters, seeing that the corals thrive in such a depth.
The geographical and geological distributions of the two corals mentioned
above is as follows.
