As was already pointed out by K.
AsANo (1950), Cyclamm£na is a genus
characteristic of the Oligocene and the
Miocene i~ the Circum-Pacific Region,
and up to present it has not beenyielded from the Pliocene. This paper
is intended to report the occurrences ofthe fossils belonging to this genus at
different stratigraphical horizons in the
Tertiary of Kyushu.
In the summer of 1949, the writer
di~covercd
Cyclammina first in the
Miocene Miyazaki Group in Miyazaki
Prefecture; and then, in the autumn ofthe same year, he found it among thespecimens in Dr. MATSUSHITA's collection
from the Eocene Kusubo formation in
Table 1.

Shimotsura-mura, Amakusa-gun, Kumamoto Prefecture.
During 1950, fossil
Cyclammitza was discovered in succession
from the Eocene Shikiyama formation inltchoda-mura, Amakusa-gun, Kumamoto
Prefecture (in the spring), and the Oligocene Nozima formation in Shisa-machi,
Kitamatsuura-gun, Nagas.>ki Prefecture(in the autumn). Of these, those fromthe K usubo formation represent the first
Eocene occurrence in Japan.
The stratigraphical distribution of thegenus Cyclammitta, known in 6 species,in the Tertiary of Kyushn, as far as has
been examined by the writer, is shownin the table 1.

It is shown in the table that Cyclammitza itzcisa (STACHE) ranges from the

Oligocene to the Miocene, not only in
Kyushu, but also in the Circum-PacificIn the Miocene
Region as a whole.
fonnation of the Miyazaki PrEfecture,
there are Cyclammina caucellata BRADY,
C. japonica A<iAKo, the characteristic
Miocene forms of Japan, and C. incisa(STACH E) found together. Cyclammiua
pusilla BRADY is found in the Oligocene
Nozima formation together with C. incisa(STACH!':).
Of the Eocene species of
Amakusa, Cyclammina pacifit;a BEct.; iscommon in the Eocene of the CircumPacific Region, while C. /ani Isui7.Ar<I isa particular species abundant in the
F..ocene of Formosa.
The writer J)clieves it an imJX>rtant
conclusion that the stratigraphical orderof the species of Cyclanmzitza seen in
Kyushu seems to hold true over all the
Circum-Pacific Region. At any rate, itis evident from the facts referred toabove, that the genus Cyclammina has
an important stratigraphical value as anindex fossil for the correlation of the
Tertiary formations in Kyushu.
Finally, the writer wishes to express
his cardinal thanks to Dr. K. AsANo, of
the Tohoku University, Sendai, and Dr .

..

T. OINOMIKADo, Chief Geologist of the
Teikoku Oil Co., for their kind advices
and comments, and to Prof. T. MATSUMOTo and Prof. H. MATsusHITA of the
Kyushu University for their kind encouragement and suggestions given to
the writer in the present study : last but
not the least is the writer owes to Prof.
I. HAY AsAKA of Kanazawa University
for kindly discussing the problem andreading the manuscripts.

Adding to them, the writer describedhere three new species of the genus from
the Miocene localities of Northeastern
Korea. They are F. koraica sp. n6v.,
F. protolongipeliolata sp. nov., and F.
Uota~tii sp. nov.
It is surely interesting that considerably manifold forms of Fagus commonly

distributed during the Miocene ep:>chalmost all over the Korean peninsula
where Fagus is quite barren now. At
present F. multinervis NAI.;AI with whichabundant fossils have been found identi·
cal or quite similar in the Northeastern
Asiatic Miocene floras, grows on higher
altitudes of islands of Utury6 and Saisyi1,
both being the marginal !'olitary islands
off the Korean peninsula. According to
NAKAI ( 1919) who studied the vegetationon these two islands, plants of the islands
especially at the higher altitudes arerich in endemic elements which are con.
sidered as floral relics on a past conti·
nent before turning into islands as they
are now.

Fagus lwraica, sp. nov.
Pli1te 5, Figures 1·3.

Description :-Leaf ovato-elliptic, smallin size, approximately 5 em long andabout twice of breadth, acuminate at theapex, broadly cuneate at the base.
Margin crenate, serrate or crenato-ser·rate, except the basal entire part.
l\fidvein rather slender, taking a zigzag
course to the apex. Lateral veins 7-9
pairs in number, leaving the midvein at
an angle of about 50°, nearly straight tothe marginal teeth, though some of thelower pairs slightly decurrent below attheir bases, the lowest pair derived quite
nearly from the base of lamina. Finerveins weak, wavy crossed or networked,
Petiole 4-7 mm long. Texture seems tobe thin.
Comparison a11d remarks :-The present specimens are similar to the following living species in Eastern Asia: Fagus
llayatae PALIB. of North Formosa (Plate
5, Fig. 4), F. Iucida REHDER et Wu.sosof Central China (Plate 5, Fig. 7), andF. crena/a Rr.U!>IE of Japan (Plate 5,
Figs. 5 and 6), Compared with them,

the fossil differs in hwing the acuminate
apex anrl the slender nerves. Among
the Tertiary Fagus, our specimens mostclosely resemble F. Nathorsti Ko:-~No et
OnJKA (1933, p. 410, Text-fig.) of the
Asigakubo flora in Shizuoka pre£., but
this Pleistocene form is characterised by
the constant and distinct marginal teeth
Further allied fossils of Japan are F.
Hayatae of M11o from the Shimokurada
lignite bed (MIKJ, 1938, p. 224, Text-figs.
6 f-h) near Kamakura and the Katada
plant bed of prov. Omi (MIKI, 1933, p.
219, Text-figs. 4 q-s), F. ferruginea var.
Milo (1933, p. 9, Plate 5, Figs. G. H ;Text-figs. 6 f-h) from the Pleistocene
lake-deposits of Yamashiro, ancl Qnercus
Stuxbergi NA THORST (1888, p. 37, Plate. 12, Fig. 7) from Yokohama. As alreadymentioned by Ko.'-1:-<o and 0Tur\A (1933),
these forms belong to the same foliar
series of Fagus as well as this F. koraica.
F. lwraica is distinguishable from F. fer·rreginea AlT. fossilis NATHORST (1883. p.
t13, ·Plate 4, Figs. 27-24; l'late 5. Figs. 111 : Plate 6, Fig. 1) and F. ferruginea
altaica SciiMAr.HAUSEN (1887, p. 206,
Plate 21, Figs. 1-4) by the decidedly
smaller size, decreased number of later·
al veins and the mode of marginal ser·ration.
Occurrence :-Ryi1hokud6, Kokangencoal-mine, N. Kanky6 D!>, E1Jgelhardtia
bed (Miocene). Colis. KoDAIRA andUoTANI.

Fagus protolongipetiolata, sp. nov.
Plate 6, Figure 3.

Description :-Leaf long elliptic, 7 cinlong 3.7 em broad, acuminate at theapex, broadly cuneate at the base.
Margin uniformly serrate. Midvein rath·er thin, straight to the apex. Lateralveins 11 pairs in number, opposite or
subopposite, diverging at angles of about

50° from the midvein, slightly decurrent
at their bases, straight to each marginal
tooth. Petiole rather slender, 11 mm
long. Texture seems to be thin.
Comparison and remarlls :-The present specimen, as shown on Plate 6,
closely resembles F. jerruginea AIT.
jossiUs NATI!oRST (18S3, p. 43, Pl. 4,
Figs. 17-24; Pl. 5. Figs. 1-11; Pl. 6,
Fig. 1), but is distinguished from it by
the long petiole and the broadly cuneatebase. F. ferruginea An. fossilis NATIIoRsT was named on fossil leaves from
Mogi near Nagasaki and compared by
NATHORST with an American living F.

jerruginea Arr. (=F. americana SwEET).
FLoRIN (1930, p. 18, Pl. 5, Figs. 5-11; p.
29, Pl. 5, Figs. 7-9 (? ) ; p. 36, Pl. 5, Fig.
12, (?)and some Japanese paleobotanists
have reported its occurrences from several localities in Japan. Y AilE and ENoo
(1930) once pointed out that the leaftype called .F.ferrregineajossilis is hardly
distinguishable from such Chinese existing species as F. jerrugi11ea Rostlzornii
figured by ET'riNGSHAUSEN in 1894. The
writer who carefully compared the
Korean fossi I specimens with modern
Chinese species of Fagus believes that
this fossil, as well as most of F. jerrugitzea fossilis NATH. of the Japanese
Neogene Tertiary has much closer
relationship to F. longipetiolata SEJ,;MEN(Pl. 6, Fig. 5) of China than to F.
jerneginea AIT. (Pl. 6, Fig. 4) of
North America, so far as leaves areconcerned, as shown in Pl. 6 for comparison. F. !o11gijJetiolata now grows inprovinces of Hunan, Hupeh, !3zechwan,
Yunnan, K weichow and Chekiang ofChina.
Lately, MIKI (1941, p. 270, Figs. 11 b,c) described some capules and leaves,under the name of F. jerrugiuea, fromthe Pinus trijo/ia bed of Aiti pref. ofHonsyu. These remains also show close69

resemblance to those of F. longipetiolata.
MADLER (1939, p. 83, Pl. 7, Figs. 21-27,
Text-figs. 27, 28) also reported F. ferruginea fossilis NAnr. from the Pliocene
beds of KHirbecken, Frankfurt a. M. in
Germany. MADLER's specimens, as F.
attenuata GorrERT ( 1855, p. 18, Pl. 5,
Fig. 6) which have been believed to be
most related to F. ferrttginea among
the European fossil Fagus, may be moresimilar to the Asiatic Fagus longipetiolata
SEEM. than to the American .F.ferruginea
AIT.
Occurrence :-RytillDkudo, I<okangencoal-mine, N. Kankyo Do, Engelhardtt'abed (Miocene), Coils. KoDAIRA andUoTA:-11 ; Kantindo, l\1eisen-gun, N. Kankyo Do, Kantindb formation (Miocene),

Fagus Uotanii, sp. nov.
Plate 6. Figures 1, 2. •DescriPtion :-Leaf small, elliptic lanceolate, approximately 4-5 em long and 12 em broad, apex acuminate, base broadly cuneate or obtuse. Margin uniformly
crenato·serrate. Midvein almost straightto the top of leaf, or occasionally takes
a zigzag course at the apical part.
Lateral veins regularly parallel, 11-13
pairs in number, diverging at angles ofabout 40° from the midvein, straight toeach marginal tooth. Petiole 2-3 mm
long. Texture seems to be thin.
Comparison and remarks :-F. Uotanii,
sp. nov. is essentially related to F.
proto/ongipett'olata, sp. nov. and F. ferrugitwa AIT. jossilis NATHORST (1883, p.
43, Pl. 4, Figs. 18-24; Pl. 5, Figs. 1-11;
Pl. 6, Fig. 1), but is distinguished fromthem by the decidedly smaller and narrower leaf. This species distinctly differsfrom F. koraica, sp. nov. of the same
locality by the shape of leaf and theKazuo IIUZIOKA

increasing number of lateral veins.
One of the leaves (Pl. 6, Figs. 5 andSa) which Kr~YSHToFovrcn (192la, p. 20)
figured as F. Antipofi from Possiet·bay
of Southern Ussuri is clearly distinct
from F. AutiPofi HEER and may be a
new species of Fagus. It apparently
resembles our F. Uatanii, but it islanccolate in shape (about 6.2 em longand 1.6 em wide) bearing wavy marginand 20 pairs of lateral veins.
Among the living species of Fagus,
any very similar equivalent of F.
Uotanii was not found so for, but F.
longipetiolata SEEMEN and F. Englcriamt
SEEMEI\ and DrELS of China seem to be
similar to it.
Occurrence :-RytlhokU<h), Kokangencoal·mine, N. Kanky9 Db, Engelhardtia

' Genus Ulmus L.

Ulmus is a common genus in forest
trees of Korea. Ulmus Davidiaua group( U. Davidiana PLANCH., U. laciniata
MA YR., U. macrocarpa HANCE, U. mac·
rophylta NAKAI and U. matzc/zurica
NAKAI) distributed mainely in northern
Korea and U. corcaua NAKAI in southern
Korea .
. Fossil Ulmus which has been re])orted
from Korea, is only U. Brmmii HEER
(ENDo, 1938, p. 326) of the Tusen forma·tion in Kogen Do. Recently Hu and
CHANEY (19·10) described three species of
Ulmus from the Miocene Shanwang floraof Shantung prov., China.
Descriptions of U. carPi1widcs GoPPERTand U. shiragica, sp. nov. distinguishedby the writer in the present disposal are
as follow-s ;Ulmus carpinoides GoPPERTUlmus carPinoicles G<"•l'liERT: p. 28,

Some imperfect leaves referable toUlmus carPi11oides GurPERT ( U. mitt uta
type of GorrEin) were determined by
the writer.
U. carpinoides Goi'PERT is one of themost common Tertiary plants in North·ern Eurasia. The Ieaf.type of Korea isquite similar to that of the Miocene
Obira series of Hokkaic\6, both being U.
minuta type of GorPERT. Out of Hokkaido, U. carpinoides has been known
from several Miocene localities in Japan.
Occurrence :-Kantindo, Meisen.gun, N.
Kankyi) Do, Kantind(> formation (Mio·cene), Coils. KooAIRA and UoTANI.

Ulmus s/zi1'agica, sp. nov.
Plate 5, Figure 8 ; Plate 6, Figure 6

Description :-Leaf ovate to ovateelliptic, generally 8-11 em long, apex
acuminate, base slightly inequilateral,round or obtuse being somewhat cordate.
Margin duplicato serrate; small teeth 35 in one dent. Midvein ~tout andstraight to the top of leaf; lateral veins
16-20 pairs in number, elegant, regularly
parallel, straight of slightly Up·curved to
end in marginal dents, leaving the
midvcin at an angle of about 45°,
though some lower pairs often wide·
angled; tertiary veins branched fromthe lateral veins on the marginal borderNotes on Some Tertiary Plants [rom Tyosen (Korea). II

and attained to the small teeth of
margin; finer veins thin, delicate, clearly
percurrent. Petiole thick, about 1 em
long. Texture seems to be thin.

Comparison and remarks :-Ulmtts
shiragica, sp. nov. is characterised by theregular lateral veins. In general habitof leaf, it is related to the living U.
Davidiana group among which U. macro·
carpa NAKAI of Korea and U. Bergmatz·
niatza ScHNEID. of China are most allied
to it.
Among the known fossils, U. diPtet·r
STEENSTH. (HEEH, 1868, p. 1949, Pl. 27,
Figs. 1-3) from Iceland somewhat
resembles ours in nervation, but differs
in the mod'e of marginal serration.
Specimens from Azano of prov. Shinano
which were called by NATHORST (1888,
p. 23, 1'1. 9, Figs. 4, 5) as CarPiniphyllum
pyramidale japoniwm ? are very similar
to U. shimgica.
Occurrence :-Kissyu-town, KissyLi-gun,
N. Kankyo D6, White Shale of the
Kissyt'1 formation (Miocene), CoiL OISIII ;Kinkodo, Usen-men, Geizitu·gun, N.
Keisyo Do, Enniti series (Miocene), Coils.
KoKAIRA and UoTANI.
Genus Zel!wwa SPAcll
In Korea, Zelkowa serrata MAKINO
and its var. langifo/ia NAKAI are now
living generally south of N. 40° in
latitude~. but fossils of Zelkowa occnredcommonly throughout the Miocene deposits of Eastern Korea.
In the present determination of the
Korean fossil plants, the writer distinguished two species of Zelkowa, i.e. Z.
Tibae Orsm et HuzioKA and Z. Uugct·i(ETTINGSIIAUSEN) KovATS, of which thelatter has been known from the following
localities of Korea :Kantindo formation of N. Kankyo Do (EN Do,

Zellwwa Tibae OisHI ct HuzroKA(MS)
Plate 6, Figure 7

DescriPtion :-Leaf oval, 3.3 em longand 1.5 em \Vide; apex like a marginal
dent, obtusely pointed ; base broad,slightly cordate. Margin dentate; marginal dent large, scperated by a deep
sinus, oval shape and obtusely pointed
at the top. Lati!ral veins 7 pairs in·number, forming wide angles to themidvein at the lower part of leaf andacute angles at the upper. Midvein
rigid, straight to the apex. Petiole thick,
1.7 mm long.
Comparison and remarks :-This typeof leaf is referable to Z. Tibae OrsHJ et
HuzroKA from the Miocene Obira seriesof the Uryu coal-field in Hokkaido. Z.
Tibae is distinguished from the known
species of Zelkowa by characters of bothends of leaf and the large marginaldents.

Many detached leaves and leavesbearing branches were examined. Zelkowa Uugeri (ETTINGSHAUSEN) KovATS
is one of the most common fo~sils in the
Miocene flora of Korea. It occured from
the Miocene deposits of Shantung prov.
of China (Hu and CHANEY, 1940), Kenga·lake district (HEER, 1877, p. 53, Pl. 15,
Fig. 19) and Ussuri (KRYSIITOFovicH,
192la, p. 22) of southeastern Siberia. Z.
Ungeri is one of the most wide-spread
plants in northern Eurasiatic continent,
and ranged in Japan at least from
Miocene to Pleistocene.
Z. Ungeri closely resembles the living
Z. serrala MAKII\o of Northeastern Asia,and is also similar to Z. oregoniana(KNoWLTON) BRoWN (1~)37, p. 173, Pl.

Cambrian i. e. Fengshanian series, but
the middle and early Upper Cambriani. c. Daizanian and Changshanian series
have not as yet been discovered. In theFcngshanian which is composed of sandstone, sandy shale, marl, slabbly lime·stone and limestone conglomerate, redcolor is most prevalent. It indicates pro·bably a marginal facies of the Upper
Cambrian formation of Eastern Asia.
In the Huangluohsien district, west of
Chinchou, the middle Fengshanian red
micaceous sandstone at a point (loc. 16)
WSW of the Hamashan colliery yields
the following fossils:

In the southwest of Haungluohsien ill·
preserved Calvinella is found crowded
along a ravine in two horizons in theupper Fengshanian red sandy shale (loc.
10), some 10 metres above the Tsinania
horizon (Joe, 11). For the Cambro·Ordovician stratigraphy of the district thereader is referred to my previous paper(19H). Further, Asioptychaspis calyce(WAr.coTT), A. cfr. ceto (WALCOTT) andTsinania sp. were contained in a redcoarse sandstone and only Pseudosaukia
srmi KosA Y ASH! in a dark red marl,both collected at a locality of Y angchiachengtzu, 5 km. SW of Huangluohsien.
This fauna is as yet undescribed except
Hamaslla11ia Pttlchra, the pygidium ofwhich is so aberrant that it made me toinstitute a new genus (19•12). It is further a remarkable fact that a pygidium
from the Middle Cambrian Taitzu formation at Hsiaohsih (Fengtien Province)in Manchuria on which ENno (l!l-H) established Hsiaohsia quadrata, new gen.
and sp. reveals a remarkable resemblancewith it. All other fossils arc describedhere except Tsinania catte1Zs \vhich will
be discussed in a following paper.

In Billingsclla jelzolensis KoBAYASHI,
new species, the shell is subqiladratc,
its hinge margin being however, shorter
1·han the maximum breadth, and biconvex, the convexity being stronger on
the dorsal valve. As usual in Billingsella
the vascular trunks are well developed,
especially on the ventral valve; cardinal
process seen on the dorsal valve to bea short simple ridge. Surface is ornamented by very fine innumerable ribs
on which account it looks very similar
to Eoorthis shafmotutzensis SuN, 1924, but
the outline is a little protruded laterally
along the hinge line in SuN's. The
holotype dorsal valve is 13.8 mm. long;its breadth 15.5 mm. at the mid-lengthand 13.3 mm. along the hinge margin.

This species is represented by an
external and internal mould of a pygiclium, 3 mm. as long as broad, which issubquadratc and strongly convex; its
marginal rim unusually broad, thickened
on the rounded postero-lateral side:On the late Upper Cambrian (Fengshanian) Fauna in Eastern ]chol

anterior axial lobe unsegmented andnon-tuberculated, broader than the pleural lobe, subquadrate, somewhat narrowing back and outlined by a distinct
furrow; posterior lobe, on the contrary,
only discernible by cross light, narrows
back gradually and terminates at a shortdistance from the rim ; pseudolobe rem·
gnizable by slight difference of convexity,
swelling back very abruptly ; surface
smooth.
Among some 15 species of Pseudagnos·tus (KoBAYASHI, 1937), P. gyps (Cr.ARI\),
1923, and P. cyclopygeformis (SuN), 1924,
may be the closest allies. The anterior
axial lobe is, however, hi-segmented in
the former, while the posterior axial lobe
is practically obsolete in the latter.
Further the median tubercle is present
in them but absent in this species.

This species has already been describedin some detail, but now it is found thatthe free cheek has a short genal spine.
The associated pygidium is twice longer
than broad, about same size with tne
cephalon and surrounded by a narrow
border ; anterior margin gently arcuate ;ax.ial lobe narrow, prominent and composed of three rings and a terminal
lobe whence a blunt post-axial ridge
issues : pleural furrows strong, but interpleural furrows are weak ; and marginalborder flat and of moderate thickness.
Five species are known of this genus
among which the subquadrate glabella
and broad pygidium arc the most significant characteristics of this species. The
glabella is more elevated in H. convexa
and the pygidium longer in H. sosanensis.

The detached carapaces can safely be

In the general aspect it reminds meof a suakid, but there is no trilobite in
the collection which is thought to havethis as its pygidium. It is a little taller
and about three times larger than thatof Haniwa quadrata and I have seen
any of I/aniwa which grows so large.

few years. The results of his work havealready bt'en published.I 1
However,many changes in the delimitation of the
Titibu System are necessary as a resultof my restudy of the area. I have subdivided the strata in descending order
as follows:4.

and Schwagcrina limestone.

Takayama Group ...................... .
Mainly, composed of black clayslatewith graywacke and chert.

These Groups, crop out mostly along
an anticline and t1vo synclines. For
convenience of description, these folds
are named as follows: Kamikuzu syncline, Anaz;nva anticline, Nitayama syncline. The general trend of the axes ofthese folds is NS0-60° W.
I collected several good specimens ofFusulinids which may belong to "Nagatoella" at Shimokuzu in the Kamikuzu
conglomerate, the uppermost group in
this district. Since "Nagatoella" is avery questionable genus I shall discuss
it in the following paragraph.

The genus was established by TuoM·
PSoN in 1936 on the· basis of "Scllellwienia eltipsoidalis var.
orienta/is
OzAwA." His original description is asfollows : " The shell of the Nagatoella
THOMPSON is large and ellipsoidal, having broadly rounded poles. Mature shellsof thirteen volutions are 6 to 7 mm. longand 3.5 to 4.5 mm. wide. The shell is
ellipsoidal throughout growth of the indi·vidual, and the poles arc broadly roundedthroughout the shell. The spirotheca is
composed of a tectum and a coarsely
alveolar kcriotheca. The spirotheca isthin in the first three to four volutions,but it is thick in the outer volntions.
The septa arc fluted throughout thelength of the shell.
The fluting is widely spaced and isconfined to the lower margins of the
septa. The chomata are narrow and low
in the inner four to five volutions andare discontinuous in the outer volutions.
Deme calcite almost fills the chambers
to the edges of the tunnel in the inner
five to six volutions, and ftlling cover
the inside of chambers from the tunnel
to the poles in outer volution."
DuNBAR and his colleagues rejected thegenus "Nagatoe/la ", and placed OzAWA's
original specimens of Schellwienia in

Scltwagerina.
In my later field worl<, I collected many
good specimens of" Nagatoella" and will
describe bter. I concluded that the spe-cimens can be distinguished from Schwa·
getina by their ellip':loidal shape, low
septel fluting, distribution of axial fil·lings, the development of the spirothecawith growth of the shell, and the number of volutions.
These features are the character:stics
by which Tno~tPso:-. established thegenus "Nagatoella ". Therefore, I accept
THoMPsm;'s genus "Nagatoclla ".
Nagatoclla seems to have developed
from Triticites by the development of thechomata and to b~ an ancester of
Doliolina and Pse:uladaliolina according
to its shape, number of volution, andparachomata.

Nagatoella fujimatoi, new species.
Plate 8, Figures 1-9

DescriPtion-Shell large, ellipsoidal,
having broadly rounded poles. Matureshell of 11-12 volntioas and have a form
ratio of about 1 : 2. The width is about
2.7 mm. and the length 5 rhm. The
spirotheca is very thin in the inner
volutions, but it becomes rathe1· thickin the outer volutions. It is composedof a tectum and keriotheca, and deposits
of dense calcite cover its surface in all
volutions, so in the oblique section, thesepta cannot be seen in the inner volu·
tions. The septa are thick, and are
fluted throughout the shell length. The
semi-circular chomata are distinct in all
volutions, and the tunnel angle is 25°.
The proloculus is spherical, very small
and its inside diameter measures about
100 microns.

Comparisons :-The general appf'aranceof this species is like Nagatoella orietztis
THoMPsoN, but its better developmentof the chomata in all volutions and thesmall proloculus serve readily to distinguish the present specimen. This
species also allied to Pseztdodoliolina
ozawai Y ABE & HA~ZA WA, but differs in·having remarkable parachomata.
Remarks :-The specific name is given
in honor of Professor Haruyoshi Fun1\H>TO, the Tokyo University of Education, from whom I have received valuable help and many suggestions in mypalaeontological work in Fusulinids aswell as for my field study in Titibu
district.
Occurrellce :-Middle Permian. In theconglomeratic limestone at Shirnokuzu,

New method of Study for Fusulinids.
The inserted photographs have beentaken of the new etching method. Previously thin sections had to be made to
study fusulinids. Since it is very diffi·
cult to make thin sections, I worked out
another way of studying Fusulinids.
The basis of the method is to etch thespecimens by acetic acid. The first stepis to polish the material with a grinding
machine and flatten the surfaces. Then,
immerse it in 20.% acetic acid for about
2-3 miniutes Again, polish with chromium oxide or red ochre on woollen cloth,so that a luster is given and the .fusuli-

l~okuro84

MORII<AWA

nids are in relief on the surface. Then,the Fusulinids are easily seen under areflecting microscope.
This method is very simple and saves
time and expense. Moreover, the new
method permits making of cross sections
and axial sections from the same individual. Previously, there was no me-

thod of making both cross and axial
sections from the indevidual.
I wish to express my hearty thanks
to Prof. Riuji ENno, for his many helpful
suggestions and criticisms, I also express my graditude for the financial
help provided by the Educational Department.

material collected by Messrs. Kenw
HATORI and Toshio ABE from the Pliocene formations of the l3oso Peninsula,
Chiba Prefecture. These are describedin this paper and the Japanese Tertiary
forms are brought into comparison withpreviously known related forms.
In the present paper, 14 of the known
30 species and subspecies of Ehrmzbergt"na
are brought into comparison with theJapanese forms of the genus.
Theremaining 16 species were omitted fromcomparison, owing · to their not being
intimately related forms.
The species brought into comparison

INTRODUCT!0:-1

The genus Ehrenbergina which was
first described by REuss in 1850 based
upon E. serrata REuss from the Mioceneof Austria, is now known to contain morethan 30 species and subspecies. These
species have been reported from remotelocalities ranging from the Eocene ofNorth America, the Oligocene and Miocene of the West Indies and the Plioceneof Japan. As l~ecent the genus has beenreported from the Indo· Pacific and tropical western Atlantic, but is most abundant in the Pacific ; its bathymetric range
is from the littoral wne down to 2000
fathoms.
The occurrence of this widely distributed genus in the Tertiary of Japanwas first made known by AsANn (1938),
who described Eltrenbergina serrata
REuss from the Pliocene Nojima formation at Nojima, Kanazawa-machi,
Totsuka-Ku. Yokohama in Kanagawa
Prefecture. Recently he (AsAt-:o, 1951)
reported a new species of the genus from
the Miocene Awakura formation at thenorthern end of the Noto Peninsula in
Ishikawa Prefecture.

Remarks :-The following species be·long to the same type with E. 1totoeusis,
namely, E. amina, E. compressa, E. ser-rata, E. sen·ata gibbera, E. sPinossisima
and E. tt·igona brazi/iensis. E. amitta isfrom the middle l\1iocene of Vominica,
E. serrata from the Miocene of Austria,
E. sen·ata gibbera from the upper Oligocene and lower Miocene of Porto Ricoand, E. sPinossisima from the Mioceneof Jamaica, middle Miocene of Haiti and
Dominica. E. compressa and E. trigona
brazilie11Sis are Recent species from thetropical wne off the coasts of the Pacificand Atlantic sides of South America.
In classifying this first type, the formof coiling of the early chambers, suturesand development of the spines are im·portant. For further classification, forexample, in the case of E. compressa andE. serrala, the E. serrata, the proportionof length to width and tapering angle
arc used. The characters and figuresof each species are shown in Table 1

side cutting, about 1100 m NNW of
Higashi·owada, Tamaki-mura, Kimitsugun, Chiba Prefecture, Lat. 35° 13' 34"
N., Long. 1:!!.1° 55' 54 11 E. Kokumoto formation, Pliocene. IGPS coli. cat. no. 67131.
Occurrence :-Hare in the Kiwada formation, but common in the Kokumoto
formation.
Remarks :-The following species belong to the same type \Vith E. bosoensis
and E. bosoeusis docorota, namely, E.
bradyi, E. carribea, E. falcata, E. mesfayeri, E. tzavalis, E. pacifica, E. pineyroi,
E. lrigotza. E. bradyi has a wide distribution in the Pacific and Atlantic Oceans,and occurs from the Miocene of Haiti,
Pliocene of California and Pleistocene of
the North Atlantic deep sea. E. cm·ribea
is known from the upper Oligocene tolower Miocene of Porto H.ico, E. falrata
from the upper Oligocene of Dominica,
E. twvalis from the Oligocene of Cuba
and E. Pimyroi from the upper Oligoceneof Dominica. E. carri!"ea and E. navalis
have been recorded from the middle
Oligocene of Dominica by BERMUDEZ(1949, p. 271), but his figures do notagree with the holotype figured by GAL·LOWAY and liEMINWAY or, HADLEY; they
may represent allied but undescribed
species. E. mesiayet·i, E. pacifica andE. trigoua are Recent species. Although
the precise distribution of E. mestoyeri
is not well known it seems to have arather wide distribution in the Pacific.
In this concern CusnMA!'; stated (1927.
p. 5) "there are numerous records forE. serraia in this region some of which
at least may be E. mestayeri. " This
species belongs to the second type, but
owing to that the original figures areinacessible and those given in CusH!\1AN's
paper (1927) being unsatisfactory, theexact charaders are unknown. E. pacifi
co has been recorded from numerous
localities in the Pacific and E. trigona

from the tropical to subtropical zone off
the coasts of the Padfic and Atlanticsides of the Americas. In classificationof the second typz, the form of thesutures, spines and the median part ofthe ventral side are the most importanth!Li:ors. The result of the writer's classification is shown in Table 1 and figured
in Figs. 8-17. As shown in Table 1, E.
bosoensis and E. bosoensis decorata are
distinct from all the other species of thistype in their characteristic raised sutures,and E. bosowsis decorata differs fromthe species by having peculiar keels andalmost straight dorsal line in aperturalview.
In Japan, one more species of thisgenus has been discovered from theenvirons of Semlai, Miyagi Prefecture.
Unfortunately the specimens are so smallthat the writer was unable to determine
its relation to previously recorded species,
it is described below.

Elzrenbergina sp.
Text-figures 18a··c.

Description :-Test small, triangle indorsal view, lozenge in apertural view,
subtriangle in side view ; dorsal side
convex, somewhat inflated at the middle
part, ventral side with a median furrow,bounded by slightly concave slopes; edge
rather sharp; short, small, outwardpointing spines from the edges of eachchamber; chambers low and broad, slightly inflated and waved on dorsal side,
depressed .on ventral side, later ones uncoiled, about 5 pairs visible ; dorsal
sutures rather indistinct, overlapping lessthan half their length, depressed ; ventral
sutures raised, obscure on the medianfnrrow ; aperture elongate, narrow, nearly parallel to the margin. Length up to
0.20 mm ; width up to 0.20 mm.
