Katuhiko SAKAKURA(Read F eb1"llary 12th; r eceived Ma y 27th, 1938)

L es materiaux etudies m 'ont ete donnes par MM. SUZUKI et TAKAI qui ont
publie un memoire sur les cou ches fo ssiliferes dans les environs de Tako-mati! ).
D'apl'es eux, ces couch es sont de g l'e:::, P leistocene inferieur, qui contient rarement des lentiHes de gravier , et stratigraphiquement, elles se rapprochent mieux
des couches de Diz6d6, de Yamabe ou de Semata (t6utes IE's trois sont du P leistocene
inferieur) que ceHes du Manzal"ien et du Kiorosien (P leistocene superiemf). Et
leur faune con siste principalement en elements japoniques.
Les etudes des faun es bryozoaires, fossileti et recentes du J [l.pon sont tres mal
connues" donc notre etude sur ces Bl'yozoaires de- Tako-ll1.ati n'a aucun rapport surla determination de l'age geologique de cette faune.
Nous avons traite seulement des BryozoairE's encroutants car l'ex istence del'autre sorte de Bl'yozoaircs de cette region n 'est pas encore connue.
Nous tenons a temoigner ici n otre reconnaismnce a MM. K6iti SUZUKI et

voulu me presenter leurs echantillons.

A New Callianassa from the Palaeogene Isikari
Series of Hokkaido
By

Takumi NAGAO and Ken-itiro OTATUME(Contribution from t.he Department of Geology and Mineralogy, Hokkaida Imperial
University, Sapporo, No. 204: Read and received June llt.h., 1938)

Three fossil species of Oallianassa have been de'3cribed from Japan, all from
Hokkaido; they are
Oallianassa ezoensis NAGAo lJ , the Upper Cretaceous Hakobuti Sandstone.
O. ?lnwatai NAGA0 2), the Neogene Poronai series and the lower part of the overlying Kawabata series, andO. in01"nata NAGAO and HUZIOKA3), the lower part of the Kawabata.
The species, to be described in the present short note, has been derived fromthe Palaeogene Isikari series. The Isikari series, underlaid by the Hakobuti andoverlain by the Poronai, is subdivided into three parts, the te~restrial and coalbearing Lower Isikari, the marine Middle Isikari or the vVakkanabe bed, and theUpper Isikari which is composed of marine and brackish or fresh-water sediments
and intercalated serolls of coal. The new Oallianassa has been collected from the
Wakkanabe bed exposed along the Sorati-gawa in the Isikari coal-field.

Oallianssa isikariensis, n. sp.
IIolotyp2:Para types:

A right manus.
A segment, probably the mm'us belonging to the il1dividual same as the horotype
A segment, probably the merus of another individual.
Horizon and locality: The Wrkkanabe bed of the Isikari series; Almma-Akabira district,
Sorati-gun, province of Isikari.
Manus: Palm small, rectangUlar in outline, longer than high, relatively thick transversely; proximal margin somewhat sinuous; upper margin broadly arched, its proximal
portion injured but apparently roundly angulated with the proximal margin, lower marginsubparallel to the upper, broadly concave with its distal portion moderately conyex; very
short distal margin between the propodal finger and the articulation with the dactylus, notproduced, slightly concave. Dorsal border rounded, the ventral one narrowly flattened withboth margins between it and the lateral surfaces angulated. Outer surface somewhat crushed
but indications are that it is moderately convex vertically and slightly so longitudinally,
with a distinct ridge below, which is ilnely serrated. Inncr surface slightly convex in a
vertical direction, almost flat in the longitudinal one save in the propodal third, also finely

The right manus of this species is di stingui sh ed from those of C. nnwatai
and C. ezoensis NAGAO in being thicker, longer, and narrower, and in baving
a different ornamentation. C. inO?'natCL NAGAO and H U ZIOKA is easily distinguishable from the present form by it much shorter and higher palm.
C. o?'egonensis DAN A l ) from the Oligocene of 'Washington has shorter fingers
and a manus with its dorsal margin straighter than in the pref'ent form.

By

Toshio SUGIYAMA(Contribution from the Institute of Geology and Palaeontology, T6hoku Imperial
University, Sendai. Read and received June 11th., 1938.)

During a field work in the spring, last year, in the Palaeozoic area near
Sakari-mati (Kesen-gun, Iwate-ken) in the Kitakami Mountainland, the writer foundan interesting fossil now forming the subject of this note in an exposure along
the Sakari-gawa at Tyoanzi, Hikoroiti-mura. An examination soon revealed it to
be a new form of Con1daria MILLER, a genus established on C0n1~la1'ia q1lad1'is1llcala SOWERByl) from the Bristol limestone in England and now known to havo
a wide geological range from the Cambrian to the Triassic, attaining its maximum
in Gotlandian and Devonian times.
The remains of Con1da1'ia are very rare in Japan, and the first record of its
occurrence was that of Prof. J. HAYASAKA2) of the Geological Institute of the Taihoku Imperial University, who found ComllMia 1'ectang1l1aris HAYASAKA in a
Permian black slate of Imo, Y AHAGI-mUra, Kesen-gun which is adjacent to the
locality of the present writer's material, in af'sociation with various kinds ofbrachiopods, including Leptod1lS dchthojeni KAYSER, of mollusca and fusulinids.
The present find which is the second is from a grayish-green fine grained tuffaceous rock of trachytic material of the Tyoanzi group3) (Lowest Carboniferous), which
has abundant brachiopods such as P1'od1~Ct1lS, Spi1'ije1', etc., bryozoas, ammonites
and tetracorals.

1'. SUGIYAMA

Shell pyramidal, probably more than 160 mm long, 40 mm broad, facial angle about 6'_
7' when restored. Faces tapering almost regularly to apex? , nearly flat in middle part andsowewhat convex toward lateral bordel'; median seam distinctly impressed on mould, butinvisible on that part of tcst preserved; each half travcrsed by numerous straight obliqueribs; ribs narrow elevated, neal'ly equidistant, though a little more crowded posteriorly, on
an average 6 counted in 10 mm, ascending obliquely forwards from the facial border to median seam, meeting there with those of opposite side in a lternation (continuous on test preserved) to form rounded angles; ribs minutely granulated on crests, granules being distinct
on test, but obscure on mould; those on mould carying 1-3 very fine longitudinal striae;
interspaces concave, 'Yide, about 3 t imes as wide as ribs, smooth on mould, obliquely corrugated On test. Interfacial border enfolded, for;ming a llalTOW shallow groove with angularedges; ribs from adjacent face:; descend into it, tum sharply fOl'wal'ds and thickened, forming two series of nodules in alternation .
The most characteristic featurcs of this fossil are 1)
the coal'se transverse ribs bearing 2) small rounded gl:anules on the cl'ests, and 3) fine oblique ridges in the i nterspaces of ribs.

In the litemture now available to the writer there is almost no species towhich the present form may safely be referred. In the first character it is much
like Connla?'ia inornata DANA1) reported by L .'G. de KONINCK from the Carboniferous of New South 'Wales, but the two area quite dissimilar in other featUres .
In the socond and third characters there is one comparable form which is Connla?'ia sala?'ia COWPER REED2) from the Con~da?'ia beds of the Salt Range. This
species though similar to the Japan ese form in facial ornamentation, has much

narrower ribs and interspaces. Further the latter greatly resembles Gonula1'ia
punjabica COWPER REED from the same horizon in the character , of interfacial
grooves.
.
GontLla1'ia 1'ectangu la1'is I-lAYASAKA is quite different in every respect fromthe Tyozanzi form. If one follows G. HOL"r in gro uping species of the genus, theformer probably belongs to her first group, Laevcs and the latter to third, Cancellatae.
Finally the writer wishes here to express hi'3 warmest thanks to Prof. H . YABE
for the kind advice and assistance given in the preparation of this short pape r.

Historical Review of Discussions on the Fossil Elephants fonnd inJapan, in the Late Yedo Period(Resume)By
Bunnosuke Gokan
As to the fossil elephants, the ancient Japanese naturalists for a long time believed, following
the explanation in the Chinese Pents'ao, that they wel'e the skeletons of dragon but later in the Yedo
period some scholars grew suspicious about its veracity, The questions of dragons had been variously.discussed since 1760 till the so·called "skeletons of dragons" found in Japan were proved to be theossil remains of elephants in 1811"-108--

Byoritu Beds of Taiwan
By

Sitihei NOMURA(Read and received June 11th, 193B)

The pre'sent article is based on the pyramidellid molluscs of the Pliocene
Byoritu beds of Taiwan. The descriptions of the species include the specimens
which were newly selected from the shell· sands derived from various localities ofthe said beds, in addition to those which were treated by the writer in his preViOll s work. 1)
The collection which was made by Mr. S. ANDO some ten years ago, is now
deposited in the Institute of Geology and Palaeontolog~, Tohoku Imperial University, Sendai. The present study was. carried out by the courtesy of Prof. H. YABE,
to whom the writer expresses his hearty thanks.

Shell of moderate size, fairly solid, elongate-ovate, or short-conic, smooth, polished.
Nuclear whorls at least one and one-half, rather small, obliquely immersed in first of later
turns, and a smnll 'rounded portion of last volution is visible. Post-nuclear whorls six,
sligbtly convex between sutures, narrowly shouldered at summit, markedly' constricted atsuture, Especially in aged whorls; last whorl nearly equal to spire in length with angulate
peripbel'y; base rather sbort, convex. Sculptured by only fine microscopic, flexuose growthlines. Apertm'e somewhat angular-ovate, oblique, posterior angle acute, anterior end slightly
produced, narrowly rounded; outer lip thin and smooth within (somewhat fractured in type);
columella stout, of moderate length, decidedly concave above, oblique below, provided witha strong, subhorizontal fold at its upper part; parietal ,vall covered with a thin callus.
Umbilicus wide. Height 4.3 mm., diam. 2.4 mm. (holotype).
This is a moderately large species characterized by its regular conic outline, smoothsurface, markedly constricted whorls at the sutures and wide umbilicus.
In my previous paper cited above, I took the specimens of this species as being identical with Odoetom-ia limpida DALL and BARTSCH. However, a careful comparison of several
specimens from the Byoritu beds of Taiwan with the typical form of Odostom'ia limpida
collected from Honsyu, it was found that the former differs from the latter by having asomewhat thicker test, shorter base, smaller aperture, wider umbilicus and more markedly
constricted whorls at the sutures.
There are several specimens of this species in the collection. The degree of peripheral

Restudy on the Lorenz's Types of the Cambrian
Trilobites from Shantung
By

Teiichi KOBAYASHI(Contribut ion from Geol. lust., Imp. Univ. Toh-yo ; R ead aud received Feb. 12 th, 1938.)

DAMES, KAYSER, BERGERON, AIRAGHI, MONKE, VVOODWARD and WALCO'I.'T havedescrib ed the primordial faunas from Manchuria, Shantung and elsewhere in Ohina
prior to L ORENZ, but the zonation of the Oambrian formation had not been es tablished until his paper came out. The Oambrian section south of Wang-tschuang
determined by BUCHRUCKER and L ORENZ contains three fo ssiliferous layers, upper,
middle and lower ones of which correspond respectively to the Ohaumitian (0711.,wngiabed), Kushan, and Ohanghia (Arnphoton bed) fossil beds of to-day, and hi.s " sanding
Glimmerkalk " with a thin baEal conglomerate beneath the Amphoton bed is the
Manto formation. Thus the fundamental divison of the Oambrian system of Shantung now in use has first been instituted by the joint authors in 1906.
In his monumental work on the Oambrian Faunas of Ohina vValcott hasrevised most palaeontological studies by previoLls students. L ORENZ'S identificationof fossil was naturally deserved his r evision . . During my stay at Washington where
I studied W ALCOTl" S collection, several questions arose in my mind as to his determination of LORENZ'S material. Ther efore I visited Freiburg i. Br. where LORENZ'S
types were kept, and straightened out these questions by actual exami.nation on
the types. Determinations of LORENZ'S , Oambrian trilobites by LORENZ, VVALCOTT

cfr, Obolus obscu1'ttSBecause the Lai-wu fauna was obtaiued from a boulder in a brook 9 km. westof Lai-wu, it is quite certain that it reveals an assemblage of a single fo ssil horizon.
L ORENZ correlated this zone as well as the lower foss il Jayer of vVung-tschuang to
the boundary between the Pamdoxides davidis and P. jm'chhamme?'i zones, H efollowed MONKE in r egarding the middle fossil layer containing Kushan fauna as
Upper Cambrian, and accordingly h e took the upper one of Wang-tschuang fora still hig her horizon of Upper Cambrian. Furthermore, the faun as of Tai-shan
and Tsching-tschou-fu were referred also to Upper Cambrian.
Although it is still far from the decision of accurate correlation between the
Cambrian formation s of the Atlantic an d Pacific provinces, it is certain that theupper layer of Wang-tschuang and the fossil zone of Tsingtschou-fu belong to the
Chuangic6 zone of the lower Cbaumitian s'eries, the middle layer of :W ang-tschuang
to the Ku shan se ries which marks off the top of the Middle Cambrian of Easternand Southern Asia and th e lowor layer of '\Vangtschuang and the fossil zone of
Laiwu to the lower part of the Changhia series, H owever, whether the fossil zoneof Tai-shan is early Upper or Middle Cambrian is uDcertain, becau. e Pseudoliostmcina
is a new genus.
.
All the trilobite genera are ' Asiatic ones except for Pe?'onopsis and H ypagnostus
whi ch are common in norther n Europe and eastern North America. P. jalla:!.' towhich P. ?'aku?'oensis and P. laiwt6ensis are closely related, appear in the oelandiws
zone and diEappears ill the jo?'chha?11/f/w?'i zone. Hypagnostt6s ranges in the Atlantic
province from' the tessi ni to the jo?'chhamrn f}?'i zone ; I:L vortex occu r s in the Dinesus- :· 122-

zone of Northeastern Australia whicp. was correlated by VVHITEHOUSE to the e:t:s~6lanszone of the Baltic Province. SAITO di:::covered an agnostid most probably identificalwith .H. latelimbc6tus in the Rinson sh ale of North Chosen. Therefore the lower
fossil layer of Laiwl1 may be an approximate equivalence of th e Rison in Shantung.
LORENZ'S suggestion as to the correlation of this fossil bed to the davidis-fo1'chlwmme1'i beds is not infalliable, because the agnositids on which he has laid special
weight are wide ranged in the Paradoxidian.

In laiwu.cns-is the axis of pygidium is a littl e broader and very convex. In the axial
outline both sp ecies are som ewhat similar, but in laiwuensis sli ght ly contracted at the midlength and more 01'I less rounded at binel. Furthermore, t h e margin a l .brim is tbickenEd on

As LORENZ pointed out, tbe pygidium from Lai-wu is similar to BROGGER'S mammillata1 )not only in t he shape of axis, but also in the marginal brim which is, so far as preserved,
vel'Y wid e at the hind, but t ends to na1'row laterally . It, however, differs from ?namm-illata
in t he position of the median tubercle which is much more an t eri or in the former than int he lattel'. The axis is f a intly trilobed; the second segment carries the tubercle; and thelength of t he anterIor two segments is sh orter t han that of the posterior one. The axis ispointed behind and therefrom a m edian furrow unites the axis with the posterior brim.
The pygidium from Wang-tschuang was on the ot her ha nd compa r ed with M ATTHEW'S
wnbo 2 ) by LORENZ, but its outline is longer and its posterior flange wider. The cepha lon
from the same locality is quite different fr om others of H ypagnostus. Its outline is somewhat quadrate; glabella and cbeek are gently and almost equally convex; glabella is half
as long as the cepha lon, subconical and truncated in front ; median tub ercle elongated and1) W. O. BROGG ER (1878) Om Pamcloxidesskiferne ved Krekling. (Nyt. Mag. fo1' NatUl'vid.) p. 56,

located at a point one-third across the glabella from the front; circum-glabellar furrow
shallow, but deepened into pits at the anteriro-Iateral angles; occipital lobe narrows toward
the center, but not completely divided into basal side-lobes. A peculiar swell of circularoutline as shown in WALCOTT'S fig. 1 is obscurely seen in front of g'labella which is, however, not quite certain whether it is an original feature or due to the secondary deformation; marginal brim nanow a.nd depressed.
Tbis glabellar outline is suggestive of BROGGER'S t"mzcattts,IJ but the long median tubercle
is present, and the cheek is not so convex as STRAND'S truncattts. 2 ) The circular preglabellal'
swelling is quite different from MATTHEW'S tessella3) in size which attains to the frontal
bl'im in this SF ecies.
So far as I can make out from the literatures, parv·ifrons appears to be a waste-basket
containing various forms, if the species is not considerably variable. Among different
forms of Hypagnosttts I could not, however, find anyone with which this cephalon is iden,
tifiable. Therefore it is certain that latel-imbattlS is a di~tinct species. However, which
pygidium of the two is combined with the cephalOl1 in one species is indeterminable,

8..8,7"WALCOTT'S suggestion as to the identification of LORBNZ'S specimens with bla7cwelclel'£ isjustifiable, but his specific name is preoccupied by AIRAGlll'S, as pointed out in my paper(1935).

As pointcd. out by LORENZ, there are several differences between his and DAMES' richthofeni . Tn his form the glabella expands gradually fonrard withollt a'n y distinct contraction
at a point of frontal pits on an axial fu1'1'OW and tl::e pits are not so· significant as in DAMES,
form. In the outline of the glabella this species resembles D. manchitl'iensis 11, but its fixedcheek is much na1'1'ower.
The glabellar outline, distinct lateral furrows and grade of granulation on t1:e surfaceare the good distinguishing characteristics of this new species.

This eranidium having a large eye-band, nanow fixed cheek and small postero-laterallimb indicatcs' its reference to the tl'ansvel'sal-is group of Chllanqict, instead of Pagoclia, withcertainty. The associated pygidium is also typical of Chuango,ict. In tnlnsvel'salis 2 ) the occipital ring has uniform l cngth, whil e it narrows distinctly frolU the middle to .both ends.
In this and some other respects this species perfectly a grees with SUN'S t?·ansv ersa·lis.

In the outline of glab311a, rather distinct lateral glabellar furrows, large eye-band, horizontal frontal rim wb,ich is longer than the frontal limb, and other features this cranidium
perfectly agrees witll WALCOTT'S megaltwus. As noticed elsewhere!), WALCOTT'S m cgalurus isdistinct generically from DAMES', a nd therefore LORENZ' speciosum is a valid name. The
d-ivergent anteriOl' facial sutures, distind eye-ridgd and eye at the mid-length of cranidium
suggest that this belongs to An01n')Ca1'ella rather than to Mailchuriella.

Although the cranidium is so incomplete, it is weU characterized by its narrow conicalglabella, deep axial furrows joining with each other at the pointed glabellar front and thenl'Unning across the frontal limb, medium sized eye, fixed cheek which is wider than the glabella and crossed by the eye-ridge, and tolerably developed frontal border. Because none of
the trilobite ge~era has such a combination of characters, a new genus Pseudoliost1'acina isestablished for it.
As suggested by this name, L iostmc·i n( 2) and Liostracinoides3 ) may be the most resembling
genera, but both of them can easily be distinguished from this genus by their narrow convex,w ire-like frontal brim. Furthermore, L'iostl'uci"a has a wider fixed cheek, smaller eyes, morecylindrical glabella and obsolete eye-ridge.
The cranidium and associate pygidium (LORENZ fig. 1) are somewhat similar to these of
Ano moca?'ella baucis4 ), but the ch eek is narrower, frontal limb shorter and frontal brimelevated in bauds. In the pygidium the number of the segments is more num erous, and thehind of the axis is more rounded in the former.
