84. Miocene Mollusca from Yamaguti~ Kozai-mura,Igu-gun, Miy,agi-ken, Northeast Honsy it, Japan
By,

Sitihei NOMURA(Read June 11th; received Decem ber 17th, 1938)...

~

The present paper deals with a few sp ecies of the Miocene mol1n sc~ collect€dfrom the sand stone bed devJ3loped at Yamaguti, Kozai-mura, I gu-gun, Miyagi
Frefecture, along the western foot, of the northern end of tlle Ab~kuma. mountain
range ; this is a new locality.
Theed species are :. Anadam abdi ta (MAKIYAMA), Ost?'ea gmvitesta. distinguish.
.
YOKOYAMA, Tapes simto?'iensi s (OTUKA), poli nices coti~az ae MAKI YAMA, NatiGal janthostoma PESHAYES, Baby~onia kozaiensi s n. sp. and Siphonali(J, SJ(ad{ceoi des n.
sp,
The fau::na though small in specific number, is of special interest because it
indicates the lower half of the Japanese Miocene on 'the one ' hand, and increases'the knowledge of the Mibcene fanna on the other. With additional" ~ew localities,
ur knowledge on ~he Miocene geography wi ll be increased'. The precise' accounts
are given in the following lines.

Type locality:-Nanseki, Kankyo-do, Tyose.n (Heil'oku-do format ion).; Lower Miocene.

The dimensions are all of left valves, ·as the types wer e described and measured by left valves only. The types are eaid to ' have 29 to 32 radiating ribs, andone of them measures: length 39·mm., height 30.5 mm., thickness of a valve 14.mm.; hinge margin 27 mID . , being slightly larger, and having a la-rger numberof ribs than the present materiaL, This . species- is 'Very closely related to A. subc?'enata (LISCHKE) in the creoulate nature of the surface of the left valve, but may be distipguisb,ed fromLISCHKE'S species according to MAKIYAMA, "in having' the gel'ltly arcuati'ng ant'croventral margin and the less produced and less oblique pos~erior end which i~ ­narrowly rounded. The ribs ..of A. s'l.lbc?·ena!a, are round-topped ' whil~ those of thepresent species are often obscurely dichotomouti." . Furthe rmore the shell appears

vVhether A. daitolcudoensis is conspecific with.A. abdita, or a di'ltinct species as tp.ought
by MAKIY AMA, r equires more material. . Some of the , specimens coJlected from Ko'z'a i-umra, are closely similar to A . abdita while other simtllate A. daitolc~6 doensis.
This differ ence, as for as the present ,pecimens. are con'c erned, if due partly tothe def.ormation by sli.bs'equ erit pressure a nd partly to the equivalved-sh ell of thespecies.

O. gmvitesta 's eems to be rather -f requent-.·in the - Neogene deposits of Japan,
and is especially abunda:q.t in the Lower Kado1;losawa series in ¥utu province(Iwate-ken). It has been r eported repeatedly from severa1 MiocE!ne deposits ofJapan, but its specific validity need ' further investigation, and may probably
disclose in ter esting featur.es_ from · :i palaeon tologic view.
. At the present local.ity, a thiek-shelled oyster is found very frequently,. but
since none of them are perfect, t~ey are tentatively referr~d to O. gmvitesta.

85. Note on' Eomontipora? from the Eocene(!)f the .Palau Islands
By

Hisakatm YABE and Toshio SUGIYAMA(Read and l'ecieved December 17th, 1938)

Very r ecently an i~terestinK fossil coral now forming tJ?e subtect of this 'note
wds collected by Mr, '8. E NDo of our I nstitute of Geology and Palaeo'ntology,
Sendai, f rom Marukyoku on. the eastern coast of Babeldaod, the main island of
the Palau I slands. According to him, it is from one of the limestone patch es ' iu.
an agglomerat e which is thought- to belong t th e Babeldaob agglomerte of Mr.
R. T AYAMA1) : thi, ' Babeldaob agglomerate likowise contains at its type locality
patches of limestone in whi ch Pellatispira and seve'r al other foramlnifera arefound. On the fossil evidence, the Babeldaob agglomerate is believed to ba Upper
E ocene in age; if the agglomerate of Marukyoku is proved really to be a men::~ber
6f the Babeldaob agglomerate, then the fossil cora;l DOW m question should berefered to . the s~me geological age.
.
The fossil coral at om disposal reveals ma ny features of EO?1iontipom lia?Ti"-:.·
so ni GREGORY from t:p.e L ower Cretaceous of E squai, H onduras, which . is the
genotype of. E omontipo1''a, established by T. W . GREGORy2) in 1931, and differs f rom .
it only in havillg h orizonta ll tabulae in cotallites; such tabulae are neither m entioned to occnr in the descrtptiou of the Honduras form nor shown in its figuers
given by GREGORY:GREGORY found the genotype of Eomontipo1'a to be a coral with montiporoid
aspect with distin ct, b~lt discontinuous columella, .and r egular trabecular coenenchyma; further its colon y has the upper surface even and finely gramllat!;ld, but
not provided with monticles or spiny processes as is common in mOBt species ofMontipom. H e al80 assig ned to this l1j:lW genu s anoth~r species, M on tipo?yi antiqua"GREGORY et TRENcrr3), from the E ocene limestone of the Fly River ; New Guinea;. the validity of this reference is, however , very doubtfu ll in our opinion.
.
The generic diagnosis o~ Eomontip om is given py GREGORY as follows :~'Mon t i culipori d ae :vith a m assive 01' brancbin g cOl'allu m with a well developed coenenchy ma composed ' of long itudinal trabeculae, which unite by their spines _into a networ k.

R em arks : As stated above, the Palau fossil can be interpreted as an Eomontipom with horizontal tabulae ; it differs from -the genotype, E. ha1'?'isoni, by having
cor allites which are much narrower and more distant, and coenenchyma whichis composed of much slender trabeculae and den se.
T abulae are somebmes very thin in h exacorals and their presence and absence
in fo ssils often entirely depends on preservation. 'While examining thin section sof r ecent corals under the microscope, it is often found that tabul ae occassionallyoccurs in a part of stock of corals to which they are habitu a lly lackin g. In the
caCie of Eomontipo?'a hW'1'isoni there· is no mention of their occurrence, nor arc
t h ey vi sible on its figures given by GHEGOlW. However , the common occurrenceof them in our coral which agrees very well ,,,ith E. ha?'1'isoni in other essential

f eatures, r emind u s that their absence in the latter may possibly be ascribed toan unfavou rable preservation of the specimen. 'Whether the Honduras and P alanfossils ar e really congeneric or not is left for a while unsettled, and the latter isprovisionally assigned to E omontipom with qu ery.
J1Iontipo?'a cmtiq'l.Ga from New Guinea was transfered by, GREGORY to EomontipO?'CL, on account of itl" possession of columella, of the great abundance of ooenenchym and luore regtllar arrangement bf its trabeculae.' Tlie origi11al debc ription
and figures, however, show ' that this cOTal bears a closer resemblance to lIIontipom
than to Eomontipom, becau se its columell a is a kind of pseudocolumella built of
inner ends of septal trabeculae, and not a rod-like primary structure, and further
itb coenenchymal tissue is more continuous.
The differences existing betvveen our Palau · fossil and the common living
species of 1I1ontipom can be summarized as follows :1. Coenenchymal tiss1.le is considerably denser in Eomontipom (?) than inlJlontipom .
2. Trabeculae of coenenchyma are somewhat lamellar in the latter genus
and filamentou s in the former, which stands nearer PO?'ites in thisr espect.
3. 'While septal spines are more or less well developed in the latter genns"
only more trace of septa are r ecognizable in the former.
Corallites of small size in the present fObsil seems to correspond to .1;he minutestructure of the coenenchymal tissue.

. ,The present specimens which are figured in the accompanying plate, comprise.only incomplete isolated valves, probably of diffe'rent individuals. However; thegeneral outline of the valves, approximate convexity ~nd the concentric growthlines can be ,observed. Judging fTom the pTe served f eatures, tne present specimens
are taken to belong to Lingula ungtLis (LINNAEUS), Figs. 4-7, ~ species which is
widely distributed in the ' Indo-Pacific region, being particularly ' abundant in thePhilippine I slands and certain parts of southern J apan '). This species is better
known undeT the name of Ling1Lla ana tina. Probably perfect specimens would require a new name for our specimens, seeing' that it also shows considerable reEemblanoe to L . shant1Lngensis HATAI2) a species, Figs. 8-10, from Eastern ShaJ?-tung,China.
.
R ecords of ~he occurrence of the genus Ling1Lla from the Neogene and younger deposits of J apan are very few, and it is inter esting to notice that the majorityof the records are from Pleistocene deposits. ' M. YOKOYAMA,S). S. TOKUNAGA4J and
K. SUZUKI and F. T~KAtJ, have all recorded Lingu la hians SWAINSON from Pleistocene deposits. The first two authors record that species from t.he Ple~stocene
deposits at Ozi in Tokyo, while the latter two record it from the environ~ of Ta:komati in Tiba Prefecture. M. YOKOYAMA6), also records the same ~pecies from th<l
Pliocene deposits of Onma, Nagaya and K akuma in the outskirt.s of Kanazawfl. city,
Isikawa Prefecture, wher e ' are developed the well known Pliocene Onma beds.
Lingtda hians SwAINSON is now generally accepted as being a synonym of
Ling1Lla 1'Ost1"I.L?n (SH,AW), ang if the previous r.e.cords are r eally of L. hians ormore co~rectly L. rost1'u/fn, then the known geological range is from the Lower
Pliocene to the recent seas. However, what M. YOKOYAMA7J figure.s as L. hians in
1927, appears to be closer to L . unguis (LINNAEUS)8 J in' having a nearly straight·

Lingula is an interesting genus from both a biological and palae()ntological standpoint and from a view-point of geology, i~s presence in strata or stratum
serve to h elp in alalysing the past conditions. Further, the approximate depthof sedi~enation of tb e strata or stratum yielding the Lingula can be als.o estimatedan d, t.he conditions of dllposition may also be judged. Owing to having- such impOrtant bearing on geology it seems worthwhile to give further r emarks in concern.
W . H. A . .PENSELER2 ) bas " shown, Ringula, is a paleic indicator of some value
Fir.s t, it is a clima ~e -indicator, since at present the genus i~ confined to tEopicaland warm-t\'l mperate seas.; second, it is- a habitat-indicator, since Recent lingulids
are characteristic of,. or dominants il,J , the shallow water (0-10 fathoms) Of estuarine
bays and delta'S on sanqy or muddy bottoms."_ _, C. SCHUCHERT"), has already given such interesting r emarks as," the greatest,
v-arriety of species of ligulids aDd discini.ds are fourid in shales and sandstones, and,furthermore, that the pJ:lysical evidence of the deposits in which sueh ~ccur is in,harmony with the character of the sediments and the present qistribution of thelittoral and shore living inarticulates." In later paragraph C. SCHUCHERT states,
that, Lingula is exposed on the tidal flats of Japan for honrs without injury , .. . _At high tide these' animals are cover~d with 3 to 4 feet of water. Their habitat
may be brackish or foul with decomposing organic matter, oven to such an ext ent
that all othe:r shell-fish may be ~illed off. N. YATSU, who has studied living
Lingula, tells us that on little estuaries in certain bays of floutheru ,Japan theirhabit.ats may be covered by sand and mud brought down by stream fresh ets, sothat all of the burro:ving sh ell fish will be desto ryed, but Ling'l./,la will still livein s~ch "'stinking places and the individuals tunnel them selves to the surface. The
burrows are from 2 to 12 inches loug, and the movements of the animals up anddown in the holes· are made by means of highly . con~tractile and r egenerative
peduncle.'?
Frolp. tne foregoing lines it may be noticed that Lingula is an indicator, of·t emperatm:e, habitat, depth and conditions of sedimentation. Accordingly, its value
in fo ssil state can not be n eglected, however, up to the present time it has been
given but ' little attention. To .the 'statemeuts of the for egoing ailthorities, one
more r em ark must -be added. Strictly speaking Ling'l.Lia4 ) may .be found in temperate seas whi.ch are llot very warm, but wben occurring, its in dividual and- specific~umber is a small one, being generally limit~d to a single species.

By

Hisakatsu YABE and Toshio SutUYAMA(Read and r eceived February 18th, 1939)

Mr. VV. HASIMOTO, ' coming back last autl,lmn from his one year g~ologicalworks in, the Philippine I slands, submitted us several interesting fossils for study.
Two of them have already been reported by us in' a pape~ entitled, " Two new
Interesting Tertiary Hydrozoa from the Philippine I~lands ", now in press; these'are Philippin actinia hasimotoi, which is a Sphaeractinid, aud Oi1 copom? laminata,
both new.
Another interesting fossil to which description the present article is devoted,
was collected by W. HASIllfOTO, from the river Hinalogan, a tributary of the river
Boac, Boac, Marinduque I sland, and found .in a block of limestone,. The limestone contains Oam e1:ina, Biplanispim, Discocyclina and Spi1 oclype'l.ts, and inconsequence, the geological age of the present fossil is, without doubt, Eocene.
. The fossil' is a cyclindrical body, externally annulated and internally provided
with a narrow cavity
which is apparently uninterrupted and circular in cross,section. The skeletal part around the cavity is relatively broad, consists of subparallel, upwardly convex lamellae arranged in a vertical series and converging tofor ~he outer and iJi ner borders of th() skeletal part; · the lamellae are perforated
and connected with one another successively by vertical or radial pillars which-are relatively stout and , straight. The interlamellar spaces or camerae are spaciousand often traversed by thin diaphragms.
.
The true nature of this curious fossil is , still in' question ;, its skeletal part issimilar to Oi1 copomfaveolata "WAAGEN and WENZEL1\ from th~ P ermian P1~oduct'Lts­
limestone of the SaLt ~ange, India, in which, however, the vertical elements are
more '.01' less lamellar and irregular, p.ever havin:g r egular, rod-like pillars as in
the ' prt:lsent fossiL . On the other hand, the central cavity 'of . the' latter strongly
reminds us of the cloaca of sponges; but there is no~ form in our aquaintance of
the Porifera with a similar skeletal structure.
It, looks somewhat like Amblysiphonella2l from the Permian of ~he Salt' Range,

China, Japan, ud of .several other countries ou · one ·hand, and to Heliospongia 1) ,from the Oarboniferous of Konsas, North . America on the other. Amblysipho1iellapossesses the central hollow ' and many camerae in a vertical series around it, .but
4asno vertical pillars; further, the walls of camerae are minutely . perforatcdand
the pores are of . quite diffeFent natu'l'e from those . of the _present fossil. The
skeletal part of H eliospongia is reticulated, and certain species of the genus issomewhat similar to the present ODe in this respect; but the vertical" elements areapparently different in nature- from the corresponding ones of ours.
lOne opinion is that the skeletal part of the presen t fossil may be interpreted
as being spicUlar, namely the spicules are well developed in one arm, being subparallel alid arranged radially, while much reduced in other arms ~hich interlocked with those of the adjacent spicules form common lamellae leaving numerous
round spaces or perforations, open; were the skele,t al elements really spicular, thenthey must be thought to have lost completely not only axial .canals but also their
entire material except fOT their outline. Actually, the original substances of theskeletal elements are fi)ntirely demolished by fossilization, being r eplaced by calcite
aDd their outline only is shown by a dark ' fring,
At any rate, there is no organism fa miliar to us which more or less approaches
the Philippine fossiL under consideration in external aspect and internal structure;
be a ~ponge or hydrozoa, it may rep~esent a ' new type and is thought worthy ofdescription under a new generic name 1I1a1,indttqtwia.

Postscript..

Soon after naving sent the proceding ' note to the editor, it was found that
Mlle D. IE MAITRE!) described several year s a go a very peculi~r fossil with themicrostructure similar to that of the Philippine form, from the Liass"ic of Morocco,
northwest Africa. It was assigned by her to the spongiomorphid germs St?'omatomo?"pha and named S. califo?'niw J. P. SMITH val'. co l~~mna?"is . l is elongate
nodular or mu shroon -like body consists ,of numerous subparallel lamellae whichappear vermiculated on the surface and are connected to one another by verticalpillars; it bears no calices.
There is some doubt about the generic position of the . Moroocan fossil; werethe' concentric lamelae provided with regul ar perforation s (see h er figure 7 on
. Plate VII) instead of being vermiculated, its r esemblance to the Philippine form
may be very close.
On the other hand, the generic ide'ntity of this fossil and . Vc?·ticillitcs budaensis WELLS2J from the lower part of the Bl1da limestone of Texas is almost beyond
doubt, both agreeing e~ch other not only in gener al form and inte'rnal stl'l~cture"
but also in size of various structl\ ral elements.' WELLS brought his fossil tmder
the genus Ve?"ticillites DEFRANCE, which ha'3 VC?"ticillites c?"etacetLs DEFR.~NCE. froni t h e Danian of France as its genotype. Vie 'have no specimens at h and of"this European species nor of .the other congeneric forms and are ac qu.ainted onlywith STEINMANN'S original description of the genotype which runs as follows: "Das
Inner e del' Segmente wird von einem lockeren Gewebe erfiillt, dessen Elem ente
meist senkrecht zur OberfHiche del' Segmente ' orientlert sind. Die Dichte d es
Gewebes scheint einem ziemlich gr08sen Wech sel unterwoFfen zu 8ein." · If this- statem ent is r eli able, it is quite evident that the Philippine and American_forms
are generically distinct from V e?·ticillites, becatlse the inter laminar spaces of them
are tr. .a.versed.

On Some Fo~si~ Species of Cancellqria from Japan
By

Kotora M. Hatai and Syoz,o NISIYAMA(Read October 18th 1938; received April 5th, 1939).-(Abstract)'The number of species of Oancella?'ia frolll Sikoku, KYURYU, T aiwan (Fqrmosa)and J apan proper is .not very g reat. The valid species ?f the genus, are the follow~
ing few, namely: -rc. hu 1c~tshnana NOMURA and RATAI

C. kobayashi·i (YOKOYAMA)
C. 'l'nac1'osp-im ADAMS a nd R EEVE
C. p l·istil;.a (YOKOYAMA)
C. 1'eeV ectna lat-i costa LOBBECK
C. ty osene-ns-is, new species
C. tho?liasiana CR<iSSE

C. k~woclai MAKIYAMA
C. n'o cl,ttlife·ra, SOWERBY
C. 1'eevectna CROSSE
C. s pengleriana DESHAYES
C. ta·iw anei~sis NOM.URA

As the ';"riter s have not had the opport1Jnity of st.udy specimen s of O. lim cLttda
YOKOYAMA, it is h er e r egarded as valid. The species which have been assigned to
the genus Oancella1'ia, but most probably represent some oth er genus, are t4~ fol-lowing few, namely:C. longisp·il·Ctta YOKOYAMA
C. t abata,i YOKOYAMA

C. lischlce·i YOKOYA il'IA

C: 'I'n~tl'aya'l'nai YOKOYAMA .

These species h ave be.en omitted from th.e present ,a rticle for reasons stated in
the original article, and ,also to b e r eject ed from the genus, are, the followi ng few,
namely:C. b ocag eana CROSSE and D EBEAUX of YOKOYAMA, C. c1"ispCtta SOWERBY of YOKOYAMA,"C. noclul-ifQ1''I'n-is .SOWERBY" of OTUKA, C. oz awai OTUKA, a manuscri pt name, C. aspel'e lla LAM . vai·. 1'eeveana CR.. of YOKOYAMA.

.

The fir8t two sp ecies are recognized by J , MAKIYA'MA as synonymous with his
O. lctl1'odai, The third on,e IS not found in tho works G. B. SOWERBY, and was probably not even described by him, alth9ugh Y. OTUKA m entions such a species.
T h e fourth one is a manuscript name, while the fifth appears to be a younK formof a sp ecies dealt with in the original article.
Thus restricted, it is· found that the rosults, although at first expected to turnout similar to the 'p reviously studied fossil species of Dosinia from Japan. show
considerab le differences. The differences may 1;>e explained by th e facts that, 1, thepresent seas of Jap~I). as well as in the youuger T ertiary f'ormations, the individualsof Oancella1'ia is apparently considerably less than that of Do'Sinia, 2, the distribution i n fossil state of this gastropod genus is much leES than Dosinia, 3, more
attention has been given to the genus DosinicL, and 4, further st~{dies in r egard to
this gastropod genus is n ecessaay. Similarity between the two genera are foundin such features as, 1, sp ecies with a long geological range in time have a wide

geographical distribution, conip~red with species having a shorter chronologicaldistribution, 2, the number of extinct species decreases as th e strata of their occurrence becomes young, 3, speci~s with ,a short geologica l range in time are
generally distributed in living ,tate, to Central Japan and to south, and, 4, thestratigraphical value of both Cancella1'ia aDd Dosinia can not be undervalued , ascan readily I be seen from their a, 'sociatod fauna ' as stated in the original article.
Age determination by mear\.· of Cancella1'i a alone is not a simple matter andu,nle, s two or more species are found from the , ame horizon, the age qan hardly
be detel'minted. However; if as man y as four species occur in the same beds, t.hepossiblity of age determination of the beds is much increased. Probably the most
reasonable method is t he r ecognition of the }ollowing four features, namely, 1,
species occurrin g in one stratigraphic sequence, but without overlapping of t h eir
vertical range, 2, t.he same, but with marked overlappin g of their vertical ranges,
3, appearing in succession but not in extermination, a) ~ Cl, 4, appc:- aring at the :::ametime but becoming extinct in succession. By fully considerin g the mothods just 'slated, the possibility of delermining th e geologica l age of th.e beds ' which yieldthi.s particular gastropod can not be neglected. However, it appears 'that the time
to discu, " t his problem in full, is not yet ripe. A nd further data are evidently
necessary to bring about conclusive ,remark s.
In regard to the eviroument of Cance lla1'ia, OUr knowledge is hardly worth
mentioni11g. However, it may be ,·tated that the bottom where Ca1~cella?'ia liveS
gene':rally consists of sand of various texture aud nature ; being common in pays or
enclosed water bodies wh ere the water current is not strong, rather than in the
open sea where wave action is considerable. The_ bathymetrical range is but aslight on e, and probably such a depth as 100 fathoms is never reached. The
majority of the records range between the. trand line to 30 fathoms, althougl?- there
IS one record 6f 63 fathoms.
As to the n umber of species, it appears that the Indo-Pacific zoological province may be enumerated in fi rst place for the Far East. In north temperatewaters t he number of species is much de-creased, in oth er words, it may be said
that ·the number of species is increased from north to south, and vice ver sa; _The above mentioned data i important in dicussing the depth- of depositionof the strata yeildingfossil Cancella1'ia', parti.cularly when the shallow wa~er sh ells
were not carried into deep \\Tater by sea waves and other agencies. And also to
be taken iuto consideration as data for such discussions is the state of preservations, especially the degree of woar.
Compar.ion of the distribution of the living ; pecies with those which occur as
fossil, is a geat aid in ,fii,'cussion of oceanic currents and migration of the past.
Together with the associated fo ssil fauna of CCLnce lla1'ia , we can know the general
physical conditions of the past .
The present work was prosecuted by a grant-in-ai.d recoived by the writer,from the Saito Ho-on kai Foundation in Sendai, to whom the writer s are endebted.

90. Fossil Cones of Balsam Fir from Send ai

.

By
\

SeidoENDO and Haruo OKUTSU(Read February 18 th; Received May 9 tb, 1938)

This report is based on many fossil cones of Abies discovered from Pliocene
deposits of several. loca,lities in the environs of 8endai. These are so well preservedin the outer and inner features to admit detailed comparison with the living cones.
The type specimen (Reg. No. 60-914) and several others are stol;ed in the Instituteof Geology and Palaeontology, T6hoku Imperial University, 8endai.
Abies cf. balsamea ' (LINNE) MILLER
Pl. 22 (12), Figs. 1- 6.
. Description: Cones large, 9.5 to 12.5 em long, and 3 to 3.8 cm wide, straight, cylindrical,
but slightly nal'l'owing upwards from the rqunc1ed base to rounded apex. 'Cone scales 4-5
in one cycle, closely imbricated, those of the middle portion about 2 cm long and 1.5-2 cm
broad.i outer margin entire and moderately curved, texture tbin and leathery. Bract scales
short and inclosed. Seminiferous scale embracing 2 seeds in hollow interior wall neal' base.
Seed with thin membranaceous wing, small, elongate, 0.4 to 0.5 cm long, a90ut 0.3 cm broad,inverted.

Remarks: These fossil cones closely ' resem ble those of the baisam fir (Ab'ies
balsamea (LIN~-r:E) MILLER) now living in the eastern North America. Other plants
with c<;mes more or less similar in aspect are Picea polita CARR., Abies fi?'ma 8IEB.
et Zucc., A. lacioca1'pa (HooK') NUTT., A . gmndis LINDL., A . cone;olo?' LINDL. et
GORD., and A. amabilis FORB.; the nrst two species mention ed above are now living·in J apan and the other s in North America. But the present cones are different
from those- of the above named ones, except A . balsamea, in the size of cone, shapeand arrangement of cone scales and concealed b1'act.
There are many records of fossil cones from the Cenozoic deposits of thevarious parts of the northern hemisphere which are similar at least in . external
aspect to the present one; to mention a few examp les : Abies SpI). recently describedby BROWN from the Miocene of Thunder Mountain, Idaho, Abies latica?'P~lS MACGINITIE2) from the Miocene of the Trout Creek beds of southern Oregon, Picea
