of it have been found dating back to the beginning of the Tertiaryage, though it is very poorly known from the Pliocene and j he
Pleistocene strata. Fifteen species of fossil Engelha?'dtia are known
to us. Very interesting to note, it is restricted not only in. geo-'
graphical but also in geological distribution. As shown jn table
1, only four species have been recorded from the North American
Eocene (in a single case from the Miocene) rocks, while the majority flourish ed in Europe in the Oligocene to Miocene epochs.
There are as many living species as fossil species in the southeastern Asiatic area, with ·a singleexceptiona.l case in central
America; Table 2 show.3 their geographical distribution :Table 2.

The present,discovery of Engelha1'dtia in Korea is particularly interesting fromthe phytogeographical point of view, in that it is a unique occurrence in the Asiatic continent, and at the same time it is importantas it suggests the course of the r ecent distribution of Engelhm'dtia
since the early Tertiary. E. lCO?'eanica shows the following characters:

A Twinned or Double Fossil "Shellof Rotalia
By

Ichiro HAYASAKA(Contribution from the Geological Institute,
Taihoku Imperial University, Taiwan).
[Read N~vember 30th, 1935.]

Among "the many well preserved fossils of marine ol'lgm collected sometime ago from the subsurface rock formation of th e
ground of the Tainan Higher Technological College, thei'e are, in
association with numerous minute molluscan sh ells, a number offorms of foraminifers, including sp~cies of some genera ·as Q~tin­q~wloculina, Spi1'Octdina, Nonion, Elphidium, Rotalia and soforth.l) A brief note describing the inter e'3ting occurrence, in thisfaunule, of small pelecypod shells bearing the testimony of having been attacked by certain gastropods, was prepared by m e in
1933~)

While picking up, under microscope, tiny tests of the foraminifers and other f08Si18 from the sieved out residue of the 80ft
sandy clay, I happened to find a single specimen of a twinned or
duplicate shell of Rotalia which, I think, may be a for~ identicalwith, or, at l.east, very closely allied to,· Rotalia gaima?'di D'O~BIGNY(= R. papillosa BRADY val'. comp1'essiu8C1da BRADY,!!)) a species
which is quite common in the younger Tertiary and later formations of Taiwan .4 )The duplicity in foraminifers, living and fossil, seems by nomeans ' a very rare phenomenon,") but it may not be llseless to1) HAYASARA : ~§W{ fiHHili:rtPJitl1;@; co jI!!.11'i'i*!f( Geological Mate rials of the Substratum of tl.,e Dune F o rmati on a rpulld Taillan).

The genus Pleu?'echinl.ls was established without diagnosis by
L. AGASSIZ, in J uly, IBM (1. c.), for Cida?'is both?'yoicles N . G. LESKE.
fhe type specimen of this species is, according to J . LAMBERT; der ivedfrom a Cr.etaeeous (?) deposit in Germany, and k ept now in theDresden Museum. In Deceinber of th e same year; in the Preface
9f the 'Anatomie du ' genre E chinus' page 8, AG.ASSIZ defined thegenus and selected Cicl'a?'is botlwyoicles LESKE as the type spEcies.
Hi.s generic diagnosis, however, does not agree with the featuresof L ESKE'S both~'yoicles; his 'Ci clcwis both?'yoi.cles LESKE' is really;:t specimen collected by M. STOKES, and perhaps a recent form probably of J11ic?'o cyphtos; but his type specimen is lost and hence thetype species is l.ull·ecognizable at present, as already, 'tated by LurBERTZ) and CLARK. In 1846,. ,however, L . AGASSIZ and DESOR threw
away the generic name and transferred their botlwyoicles in T emnop le'Lmls. Th e type specimen of T emnople1.o?"US botlwyoicles is a fin ebare t est in MICHELIN'S ~ollection (L'ecole des Mines i'n Paris :labelled "Coll.

. S. NISIYAMA 'their T ernnople1l?'1lS botlwyoides is identical wit.h LESKE'S Cida1'i~
botlw'yoides, it is now quite evident that their diagnois does not
apply either to the fossil species figured by KLElJ.'l" and describedby LESKE or to the S"pecies jn STOKE'S collection. This specimen(in P aris) was errone"Ously taken by AI. AGASSIZ (1. c.) and by later
writers as the type specimen of Pl ~1l?'echin1ls botMyoides. LAMBEKl'l)>in 1907, gave a new name Opechinus rnichelini to the Paris specim en based on the description of AGASSIZ2 ), but the specimen according ' to' MOR'l'ENSEN cannot be refelTed to the genus Opechin1(,s ;the last author examined the type specimen and found that its des;cription by AI. AGASSIZ is in.correct. MORTENSEN unfortunatel.)'u sed the generic name Ple1l?'echinus for it, although the namemust be rejected from the story. cited above . . Neither Ple1l?'cchin1l8
DOl' Opechin'ilS being applicable to the Paris specimen, its genericname must be put . into a renewed considei'ation. Judging fromits description and ' figure, it seems to be congeneric with a small
sea-urchin from ,Japan, . described in 1863 by AI. AGASSIZ ' under
the name 1'ernnot?'erna Swlpt1('rn, as stated by Cq.RK and DODERLEIN.
Later the specimen was believed to be a young T ernnople1w/.{,sha?'d'Wickii, and Ternnot?'imw was .h ence placed ih the synonymy of
the T ernnopl e'l.lnls. In 1911, LAMBERT and p. THIERY proposed a
J?ew generic name Dicoptella for the species, under the old !'lile of'once synonym, ever synonym'; this action, however, is not tenable
and Ternnot?'e?na stands now valid.
The genus T ernnot?'erna is sufficiently distingui::hed from
Ternnopleu?'us by its usually non-crenulate tubercles, (though crenulated in some large specimens of sC1('lpt1('rn), the uniform size of thespines and the uniform aspect of both sides of the test a.' totuberculation. Since the genus was recently so fully revised by

A . single specime.n at hand is about 16 IDID, in di!jmeter ap.d 12 mm. inheight. It ;has 14 interambulacral, and 16 ambulacral plates in eachcolumn; though lacking s pines, oculo-genital ring and buccal membrane,
it is fairly well pl'ese l:ved and still retains partly its natural colouration.
rl1e description of the specimen is as follows:. , Test rather high (0.75 of diameter), beautifully rounded above, slightly
curved inwardly at peristome, gill-slits indistinct. Peristome 6:5=. indiameter, l~ e ing about 0.4 o~ that test. Apical system, wanting, vascant~Tea about 4;mm. jn. diamet er.

comprises, on the otl~er hand, only one particular form characterizedby having only five buccal plates and tube-feet . in the buccal

Nagatoella, A New Genus of P ermian
Fusulinids.
By
M. L. THOMPSON ,State University of I owa, 101m City, 101\'[t[Received February 3rd, 1936 j rcad Febrnary 29th, 1936]

In 1925 OZAWA (8)1), describing for the first time tho extremely rich fusulinid fauna of the Perinian of Nagato (southern
Japan), coined the term o?'ientis for a form which h e regarded
a now variety of T?'iticites ellipsoidalis (STAFF)- he illustrated
three i'i pecimens of thi s form, all from different localities, T?'iticites ellipsoidalis (STAFF) [= Fus16lina ellipsoidalis STAFF (11)and Schell1.uienia ellipsoidalis OZAWA (8)] was originally describedfrom t h e Upper P ennsylvanian of Iowa. Dnring my studies of
Iowa fusulinids I have studied for comparison tho descriptionsof all known closely simila~' form"" but I was not able to determine definitely the generic affinities of OZA \VA'S types of T. ellipsoi dalis o?'ientis. Through the courtesy of the Geological Institute of the Imperial Universtty of Tokyo, and particularly throughthe kindness of Dr. T. KATO and Dr. T. KOBAYASHI, I have had
the opportunity to study the illustrated sections on which OZA.WA
based his original description, These specimens have proved to
be of more than ordinary intere8t in regard to the classificationof the fusulinids and my restudy of them in the light of ourpresent detailed knowledge of the fusulinids has yielded certain
information which I believe is worthy of publication. It seems
to m e that these specimell'3 represent hvo species rather than one1) Numbers refer to bibliography at end of paper.

variety, and they are apparently not referable to any previously
described genu s. I am, therefore; proposing the nevv generic name
J.Yagato ellcL for them with Nagatoella o1'icntis (OZAWA), 8 . s. , as the
genotype. Also, I am ' proposing below the ' new specific name
NCLgatoella kobayashii for part of OZAWA'S original types.
R ecent studies of 'P ermian fusul'nids h ave gone to sh ow that
unusually rapid evolutionary changes took place within thisfamily ' during the upper portion of Lower P ermian and the lower
portion of Middle P ormian times. In the upper por tion of theUpper P ennsylvanian, or Upper Carbonifeou:::, only one genus off usulinids, namely T1'iti cites, occurs abundant ly and only two or
p ossibly three other genera are k nown to be present in thesestrata. I n co ntrast to this , mall variety of genoric types in theUpper P ennsylvanian, twenty-six gen era h ave been recognized int he P ermian. Both of the k nown r epresentatives of the ne,·\' ger.us
Nagatoella are associated with the genus Doliolina SCHELLWIEN(9,10), and one 01' them, .1V. lcobaycLshii, n . sp., is also aSEociatedwith the genera Neof tLs'LLlinella DEPRAT (3), Pamf'LLsu lincL DUNBAR
and SKINNER (5), and OzawcLinella THOMPSON? (12)-these foura, 'sociated generic types indicate Middle Permian age,

Genus Nagatoella' THOMPSON, n, gen.
The only species which I can refer definitely to th is gonU'S
are N. o1'ientis (OZAWA), the genotype, and N. kobayashii , n . sp.
described below. The form which DEPRA'r (4) described as Pusulina lepidcL in 1914 from Cammor,t and which OZAWA (8) described
as 8chellwienia lepida in 1925 from Nagato may r epresent thisgenu,::, but from a study of the publish ed illustrations and dos- I
criptions, I am inclined to doubt that it is congeneric with N .
o1'i entis, though it may b e regarded by some as a primitive 1'0presentative of this genus. .
From a study of the holotype of the genotype and the typ esof the only other known congeneric form, I have dra,·vn up thefollowing generic diagnosis of Nag atoella ,D iaJnosis oj Na,qatoella.-Sh ell large, ellipsoidal. Axis of coiling esse nthlily

the remaining oute r vol uti ons becomes sligh tly larger. The septa are nume rous.
They are composed of the downward defiection of t he t ectum of the spirothcca
and a lighter less dense laye r ou the posteri o r side which may be the downward
e x tent.ion of a portion of the keriotlteca of 1·he spirotheca. TJ,e fepta are ve ry
heavily coat ed by layers of densc calcite whicb are not developed in the outermost volutions, but which essent.ia lly fill t,hc cl1'l.mbers in the pola r regions oft.he inne r volntiOlls. These deposits of dense ca lcite increase in thickness toward
the poles ~ll1d t hey extend from the septa onto th e upper and lower surfnc:es ofthe spirotheca. The e xtreme basal port.i ons (If the septa are acute ly fiuted atrathe r bro ,dly spaced inte rvals and the forward fold of OIle septnm joms the backward fold of th ~ following septlllll fa as to form a very low ope ning from the baseof the followin g chamber. Thesc opening3 are later closed, after th e tunn el isdevelope'l, by the dense Ccllcite layers whieb cover thc septa. The fluting increases in intensity o nly slightly poleward from the tunnel. The proloculum isessent.iall y spheric d and it i'i of moderelte s ize. The she ll is essentially symmetrical thronghont g rowth, and the mte of increases of th e chambers is very

The genu s Nagatoella appeares to be a d irect des cendent of
the genus 'P1'iticites GIRTY (7). Nc£gato ella seems to have d l'YUloped from typical 1'?"iticites by changes 'ivhich included a r edLlction of the chomata, a more uniform and different developme ntof the septal fluting, a mor e gI'adual incr ease in the thickness ofthe spiro theca with growth of the indiv idual, the c1evelopem ent of
the dense calcite deposits on the septa and spirotheca, and th ech ange of the general development of the shape of the sh ell.
'P?'iticites o?"dinat'us CHEN (2) of the Swine limstone, \\7hich isprohably upper L ower P ermian Or possibly lower Middle P ermianin age, of souther n China represents the group of highly developed 'P?'iticites from which Nagatoe lla was probably developed.

As was pointed out by OZAWA (8) in his original descriptionof the genotyp e, the sagittal section of Nagc~to e lla r esemble.'3 sag ittal
sectiol1'3 of Doliolina SCHELLWIEN. Also, the shape of the 'S hell,of Nagatoell c~ r esembles that of Doliolina, H owever, the similarity of these two genera i. ' entirely superficial for, in contrast to
Doliolinc~, Nagato ella possesses a tunnel bordered by chomata, its
septa ar e fluted, it has dense calcite deposits on the septa andspirotheca, and it does not possess parach omata.

I h ave studied all three of these sp ecimens in gr eat detai~ and I
have r each ed th e conclusion that, although they are closely related,in the light of our present detailed knowledge of the fusulinids
they sh ould be r egarded as repre~entiJlg two rather than ones pecies. I am , accordingly, preserving OZAWA'S Dame for one ofthese specimens (s'ee P I. II, figp, 1, .2) and I am h er e designating

it as the holotype of N. orientis (OZAWA). I 11m r eferring theremaining two specimens, originally illu strated by OZAWA as N.
o?'ientis, to the new species described below as Nagatoella kobayashii.
The normal procedure would perhaps be to r egard OZAW A'S two
illustrated conspecific types as r eprE'.'3entillg N. o1'ientis and m ak e
the third specimen the type of a distin ct species. However, I
wish to base the new genus NCLgcLto ella 011 the specimen illustrated
as figures 1 and 2 on plate II and I prefer to preserve OZAWA'S
name for the genotype.
Since a part of OZ AWA'S original deEcription of this species
was based on specim0ns I·vhich I am now referring to a distinct'specieE", I am r edeEcrib:ng N. o1'ientis bafie cl f:'o lely on the holotype
as follows :Shell large, e llipsoidal. Ax is of coiling essen ti a lly stnlight. Lateral slopes low
and convex . Poles Yery h lu nt and broad ly rounded. The innermost vo lution issubspherical, the sec.ond volution hns a form ratio of abou t 1 : 1.6, and the re .maining outer volutions hav e a form rati o of a bout 1 : ~.O. The holotype consistsof t en volutions and it m easures about 3.3mm. in width and 6.6mm. in length .
The spiroth eca is very thin in the inn er volutions, but it becomes rathe r
thi ck in the outer volutions. It is composed of a tectum and a ke ri otheca, anddeposits of dense calcite cover its surfaces in all volutions except the outer one.
The alveoli of the oll t er volutions are ve ry coarse. The t hi ckness of the spiro'theca in the center of tt e first to. the nint.h voluti on meas nres 5.0, 8.0, 10.5, J2. ~ ,17.5; 40.0, 52.5, ' 61.5, and 87.5 mi crons, respectively .
The proloculum is essentially sphe rica l and its inside d iameter m easures about'140 microns. The· rat e of expansion ~f th e she ll is ratlwr un iform and the tot.a l'widths ·of th e first to t he n inth vo illtions mea~ure 310, 425, 565, 750, 960, 1275,
1625, 2050, and 2550 microns, res pectively.
The septa nre th ick. They nre composed of a tectum and a lighte r thi cker
layer on the posterior side whi ch is apparently a continuation of th e keriotheea .
. Eithe r sid e of t.he sept.a is coated wit.h rather dense thi ck deposits of calcite
whi ch essen tially fill th e chambers in tbe polar regions. TbeFe deposits extend.ont o the lowe " and upper surfaces of ~be sp irotheca. The extreme lower portionsof the septa are rather acute ly fluted at regul a r inte rva ls fm d the forll' arc! foldof one septum joins th e backward fold o~ the foll owing septum so as to form sm ,1I1
. opel~ in gs fr om th e base of one ,chall}ber. t o t,h e base of th e foll owin g chnmber .
. Th e m iddle 'lnd upper port.iolls of t he septa are essent.ially u l1f1uted. The open ings at th e base ' o.f the septa nre closed in the inlie r vo lutions by the dense calcite deposits on the fepta. However, the closing of th ese open ings is slightly. behind the de velopment of th e tUlln el.
The tunnel is very low and broad. It is only about one-third as h igh as t,hechambe rs and the tunnel :Ingle is slightly b :rger than 26 degrees in th e ninth

Nagatoella o1'ientis may be distinguish ed from N. lcoba.yashii
n. lOp., by its Im·ver and morc weakly developed ,'eptal fluting,its h ea'vier deposits of dense calcite on the septa and spirothecaand by its slightly more rapidly expanding sh ell. N. o1'i entis
r esembles in general appearence 'T1'iticites o1'dinatus CHEN (2) of
the Swine limeston e of southern China, and it ,'eems probablethat lYagatoella develoI>ed from this typo of h ighly developed'T1'iticites, H owever, in 'P, O1'dinatus there are well developed h eavychomatn. throughout the shell and the septa and spiroth eca do
not contain the heavy deposits of dE:n, 'e calcite found in N. o1'ientis.
Occ'tl1Tence. - This species occurs in the Permian limestone,
pruoably Middle Permian, of K aerimizu, Akiyoshi-Dai, Nagato,
where it is aEsociated "with D oliolina Clatldicle DEPRAT (see PI. II,
fig. 3).

m:crous.
The se ptfl are thiek and numerous. The septfl.! count for ti le first to thetenth volution of th e illustrated sagitta! section is as fol lows : ]0, 13, ]6, Hi, 16,
20, 27, 28, 27, and 30. The septlfL are composed of the dowJ1w,lrd defl ection of
the tectum of th e spirotheca and a lighte r th icker laye r on the posterior sice
whi ch a ppears to be th e downward de flection of th e kerioth ecfl. of th e spirotheca.
There is tt suggest,ion, h owever, t h at there is a defin ite lin e of separ>ltion betwee n
th is lighter hlyer of the se pta a nd the ke riotheca. Either side of the se pta is
coateel by de nse calcite " 'hi ch in creases in thi clmess ' polewn I from the ce nterof t ile s he ll an,! esse nti a lly fill s the ehMnbers in th e ex tre me pola r regions of
the inn e r nine t o t en volutiolls. This dense material s preads onto the upperand lowe r snrfaces of th e spirot.heca. The :::eptal fluttin g of this species is rather
typi cal of th e genus, but, the flutin g extends higber up the septa th;m in the
genotype. The small openings at t.he base of tli e sep!a became closed by t hed en ~e calcite deposits of the septa and spirotheca as the t;unn el was formed tofurni sh co mmunication bet'Yeen the chfl.mbers. These openings at the base of the
septa remain open only betll"ee n the chambers of the outer one or two "olutio ns.
The tunnel is low and wiele. It, is abou t, one-thil'd to one-half the he ightof the chambers. In the ninth vo lut.ion t.he tunn el angle is slightly less t han
22 degrees. I n the inner s ix vo lutions the tunne l is bodercd by ve l'y low essentially sy mmetrica l choma'a, but in th e r emaining outer volu tions the chomat·a areapparently n ot deve loped. The tunn el is not develope ,l in th e outer pal't of thelast volution.

Nagato ella kobayashii can be d istinguished from the only
other known r epresentative of this genus, N . O?'ientis (OZAWA), by
its slightly higher and narrower septal fluting, its . lighter deposits
of dense calcite on the septa and spirotheca, and its ,'lightly more
slowly expanding shell.
OCCt~1Tenc e. - Thi s sp ecie8 h as been found in the Permian
limestone, probably Middle P ermian, at two localities in Nagato,
north end of Ofuku-Dai and Nakamura of Ominemura, and it is
known from six specimens. However, at one locality, Of\1ku-Dai,
it is known ouly from an axial section (PI. II, fig. 6) ; whereas,at the other locality, Nakamura, it is known from a centeredsagittal section, a parallel sag ittal section (PI. II, figs. 4 and 5),
and three random oblique sections. It is, therefore, possible thatthese two sets of specimens are not conspecific, but, in regard to
the septal fluting, dense calcite deposits and all measurable data,- ( 21 ) -202

they seem to be identical. At OfLlku-Dai' this species is associatedwith Pamfv s'I.llina? edo ensis (OZAWA) and at Nakamura it is associated with _lYe ofl.l s~~linella simplex (LANGE)?, Doliolin a :;:p ., andOzawcLinella? sp.
