The Geologic Significance of the Recent
Mollusca fr01n the Vicinity ofIsinomaki, Rikuzen.

SITIHEINOMURA and KOTORA HATAIContribution from th e Instit.ute of Geo logy >lnd Pnlaeonto:ogy,
Toboku Imperial Universit,y, Sendai; J apan
[Received July 18th" 1936; read September 26th., 1936]

The ~he Hs compri sing tho present note wei'e collected fromthe fand beach of Nagahama, stretching bet'n-een I sinomaki at thewest to 'Waianoha at the cast, and bounded by the Kitakami -g?wa,
a. large river at the former and by the inlet to Mangoku-ura at
the latter; the length of the beach is about two and a half 1ulles
with a maximum breadth of about seven hundred yard .. or more.
This beach is free from muddy material s and rocky shores
and consists of E'and only. According to the sea chart No. 72,
publish ed by the Hydrog raphic Departmont of the Imperial Japanese Navy, the adjacent sea is a very shallow one and with. avcry gently sloping sea bottom. Sand continues to a depthoi'some 30-35 m eters before grading into muddy material at, a distanceof about two miles from thA 1:' h ore line. Beyond the dnpth of35- 40 meters the sea- bottom becomes rocky. Since no small river
empty into this sand beach , and since it is free from muddy or
rocky materials, the shell faun a is a small one. The geographic
distribution of Bamea dilcLtata., RaetcL magn~fiw, Vol se ll a hanleyi~
Epitoniu?1'/. aC~lrni?wt'urn and Ling1LZa llng~Li s h aye been extend ed
by the present c·oHection. The total number of species collected
are given below; those marked an asterik indicate the abundant
forms and those with two asteriks ver y few individt:al number.

m ollusca ' or fr a'3h-water 8h o11s is aL'0 a Jiotqwor thy; fcature of th epresent small collection . .
The, r ock-inb.abiting speci es wer e all collected fr011'1 about 300
meteT;; or slightly more from tb.e eastern part of the beach where~re found r ock y shores of their original habitat.
Prevailing windand currents seem to be responsible for their pre8ence on the Eandbeach wher e they do not normally live. There are some mud-loving~peci es in th e collec tion, but tb.eir numb.:r is a small one, beingr epre8ented by ei th er a single i80lated valve, or by a few individuals, showing tb.at tb.e sand enviroDmeot was unfavorable. The
frosh -water and land shells 8eem to have been carried .down to
the sea by the Ki takami-gawa and brought tq the beach by theagency of currents.
The varied fauna foun d on this beach is valuable in explaining
or g iving as examples the fo llowing 8tatement by TWENlIOFEL.
According to TWENHOFEJ}>, "In 'allY cons ider~tion of the en vironments of organisms, fonr phases of the individual organic
history . mu:;t be considered. The8e are the environments, in wb.ich
the organi sms lived, the el1viromnents in ,,'hicb. they died, theenvironments in whicb. the dend boelie,' a nd appenr1ages end ured
afte r death, and the environments in which the plieservable r emains
were entombed."Thus 'iVe find that th o p resenco of r ock -inha biting f'pocies str ewll<;>]) the sa nd beach apart from th eir original ha bitat is a good
example. Consequently, t he first phase of tho rock-inhabiting
species was t he rocky-shore about 300 or sligh tly more m eter :;apart from t b.eir point of discovery, th e 8econd phase wa,' probably
th e shallow water adjacent t.o tb.e rocky-sb.or es, and the third pha.e
is where they were found. Absumin g that the fourth phase would
b fou nd, it would probably bQ in the sand beach or at a placenear by.
Such examples are frequently m ot with a nd brought to ourattention when collecting r ecen t sh ells from the strand line. It
also seems that m.ore attention, than hitherto given, should bv
directed along such facts. K nowledge of such phenomena areimportant in interpr eting the conditions under which the fossils

on·ce·lived. Further, we hope to g ive further examples in the futuretogether with our views on other lines of interesting work or thatwhich may be applied to the fossil fauna within the scope of ourstudy. Without ' further studies on the various features of ther ecmit molluscan · fauna, a full inrtepre't ation of the fossil one is'110t to be expected and an attempt to do EO, cannot be regarded'
as reasonable.
I n order to bring A bont inter esting r esults from a fossi l fauna,tl, e fo llowlng pointfi 'sholl1d be g iven cOl1-'ideration, those points
are ; (1) t he kind of fauna common to the (a) tidal zone of sand v,
muddy" griwelly or rocky environment, (b) subtidal zone of such'
habitats, (c) and zon e'S of various depths of various h abitats or'environments, (2) the kind of falma common to the (a) open s'ea , (b) 'areas n ea r mouths of Jarge rivers, (c) estuari es, (d) bays, and (e)promontori es, (3) the kind of fauna common in habitats of high or
low sali~ity,· or, brackish water8, .stagnant waters, and etc., (4) the
kind of faun a common to rough water and that common to quiet
water, (5} the influence of oceanic currents, prevailing winds and" T uumni ". on the living and dead fauna, and: (G) the four phases
6f environment stated by TWENHoFEL. Also studies ar e neededalo])g the lines of the distance a dead shell may be carried, either
by oceanic current::-, prevailing winds or other agencies. Furtheri t is a1::o nece::mry to make observations on the distance a deadshell may be carried !rom the shore sea-,var ds, from tho sea landwards, froin the beach up on the land .

Shell-repair
AmoDg the numerous specimons of J"JIle?'ctrix ?1w?'et?'ix LINNAiws
collected from Nagahama beach, on e was found to have a sort ofshell-r epair line extending from behi.nd the beak to the poster o"ventral margin of the r ight valve.
This groove extending from the beak to th e postero-ventral
ma~gin is' about O,5mm. at the broadest point, and merely a line
at the beak; the concentric growth lines do not appear to tra.ns~
velise this groove, but 'b ecome very strcm g 'upon r eachi])g it andall a1:e 'directed upwards or dorsally on both sides of the groove,

if; not in the least indicated or found as traces ' on the inner sideof the 'hell.
I t is at present hard' to decide vdlother this may bo a case of
f'h ell-repair or a case of abnormality, Ho\l7ever, it is inter estin g'
to find such a sh ell in the collection. It may a lso be stated that,i t is gen eralIy regarded that shell s sho'wing traces of sh ell-r0pair::I re indicative of shallow water origin . ThuE', in fossil state t hi:'(l::ltum may be found to be of importance in dealing 'w ith thedc·p th of deposition of the strata yielding such inter esting foss: 113,

Recent Concretions
I n the collection from Nagahama was found a right valve bC'longing to jJ{e?'et?'ix m eretrix LINNAEUS, in the process of becoming::I concr etion, The valve if; not much WOl'll, the teeth on ly ::Ireslightly abraded. Sand grain s togeth er with fragm ents of sh ells
helonging to such genera as Tellina. , JlfytilttS, R aeta, UmbonitLm::Ind Co?'bic1tla are found ad·hering to the greater part of the innerf;urface and also to the sides of the exterior surface of th e sh ell.
Tho sand grains ar o comp::lctly cem ented to th e sh oll, g iving to·it an aspect of a true fossil.
This sh ell was fou~d on the strand line of Nagahama beach,
not far distant from the small town of ' Vatanoha.
Concretions, e::::pecially recent oneE', are in ter estin g ill fioveral
1'0l'lY'ct.S, and their charactoristics h ave been dealt with by TWENn OFELl),
The p rocess by which the present concretion had begu n• i ' h:1.rd to ::::ay, but it may be possible that decaying organic maUrr
may h ave been one of the causes,
However, it appears that the time r equired for the making ofa concretion not only differs according to the r esu ltin g size, but
al:::o to the kind of nuclei. I n the present case it appear s th atvery little time has elapsed to make th e concretion in the viewthat only the teeth have been abraded r egardless of th e fact that
other surfaces are expo~ed. Also the sand g rains cemented on
the sh ell are also sligh tly smoothed, probably by sand abrasion.
Anoth er concr etion ' specimen in the collection appears to havede,v eloped around the burrow tub s of certain mar ine annelids sucha,' those belonging to A?'enicola. At present ther o are several

(Resume)Preliminary Report on Some Cretaceous
Plants from Karahuto
By

MiE'aburo SBIMAKURA
The structure of some Cretaceous plants collected from Karahuto (South
Saghalin) are studied under the microscope an d their afliuities are discussed.
The material comprise;
1. Cladophlebis jrigida (HEER).
Several pinnulae with well preserved vascular bundles.
2. ? Nilssonia sp.
A pm·t of parallel-veined leaf: it is more simply constructed than in Nilssonia or·iental·is described by STaPES.
3. Nipponophyllum sp.
A part of parallel-veined leaf with well deve loped palisade t issue, hypodermis,
endodermis, and . sclerenchyma, without resin canal. In structure it ·is n earer to
NipponophyZlum conlait'i jonne Sl'OPES et FUJII than to allY other gymnospermous
leaves such as Ginkgo biloba , A1'CHtCa7'ia Bidwilli, P odoca?'1)us Nagi, Co?'Claites spp.,
Nilssonia o?'ientalis, an~ DesmiophyZlum Solmsi, but the two are n ot the same in
species.
4. Bmchyphyllmn spp.
Two forms are found: olle is quite identi cal wiLh Yezonia vulga?'is S'roPEs et
F UJII (Brachyph yllum 1:ulgare), while the other is structurally n ew, and is some:what like B. crassum.
5. Geinitzia and C?·yptomeriopsis.
-(1 20 ) -

875
Three forms are found: the first form is identical with Cl'ypt omeriops~ ant·iglla STOPES et F u.TII; the second, represented by a curvecl acerousleaf, somewhat

resembles Geinitz'ia ReichenLacMi HOLLICK et JEFFREY in stl'Ucture ; the third isa poorly preserved bran ch with compressed linear leaves.
6. Piceophyllum sp.
Leaf of Picea sp. with two res in canals and a vascular b undle surrounded bywell ' developed end odermis.
.
7. Strobilites sp. (aff. miCI'OSpOl'ophonLs HOLLICK et JEFFREY).
Staminate strobile of taxodiacean or cupl'essacean plants.

On the Classification a nd Phylogenetic
Relation of Gen era of the Melobesiae
By
WATARUISHIJIMA(l'1,ead Nov. 30, 1935; I'eceivecl Sept. 8, 1936.)

At present OUr taxonomic knowledge of the Melobesiae is far
from satisfactory. Moreover, in our country, very little attention
h as hitherto been devoted to the r ecent forms of this g roup.
For a long time great diversity of opillion has prevailed as tothe classification of the Melobesiae. Of prime importance for thispurpose is the disposition of conceptacles according to M. FOSLIEand the microf' tructure and developmen t of r eproductive organ
according to HEYDLICH. The controver sy continued until Mme
Paul LEMOINE for the first time, in 1911, called attention to theanatomical distinction recogniza ble between various genera, which
has a very important bearing on the determination of fossil forms,
because they can hardly be expected always to have traces of
their r eproductive organs preserved. I n treating classification, ofcourse, we feel the rieed of studyin g th e shape, position and structure of concr·ptacles.
In 192.$, Mme LEMOINEt) established a new genu s JJ1esophyll~6m
fOT species h avin g the di stinctly stratifi d and zonate hypothallium
previously con sider ed by her to be characteristi c of the genus
L i thophyllum , combined with the many-orificed tetrasporangial soripreviously considered characteristic of the genus Lithothamnium.
The geological range of the genus 111esophytl~6m is Upper
Cretaceous to R ecent, its species hi.therto known being; ]J1. pa?'onC61,

New Species of Foraminifera from
Aki-gun, Tosa Province, Japan(Studies on the Fossil Foraminifera from. theNeogene of Japan, Part 7.)
By
KIYOSI

ASANO

Contributiou from the Institute of Geology and Palaeontology,
T6hoku Imperial University, Sendai, Japan.
(Read and received September 26 th ., 1936.)

It h as been known for many years that some of the Neogene
rocks of the coast of Aki-gun, Tosa ProvincE', Japan contain
ForanJ.inifera in large numbers though we have no information
published about the detai ls of the fauna'.
The present article comprises only descriptions of uew forms
of Neogen e and r ecent Foraminifera collected by Prof. H. YABE
and Mr. S. NOMURA from the dist.rict. General accounts of thefossil foraminifera and of the recent forms from the adjacent 'rosa
Bay will appeal' in my arti:cre':' enti.tled, "On Recent Foraminifera
found in TOEa Bay and F ossil Foraminifera from. th e Pliocene of
Aki-glllJ, Tosa Province, Japan ".
A t this place I wish to expreFs my sincer e thank to Prof.
H. Y ABE for kindly correcting this note before pll blication anda lso for the suggestions given me throughout t he course of study.
Acknowledgements ar e also due to him as well as MI'. S. NOi\ITm.A
for kindly submittin g their collection to my study.
