Introduction   This investigation is intentioned Åío obtain the ecologic criteria of the Recentforaminiferal fauRa in the Kii Strait foy the basis of paleoecologic research in thePaleo-Setouchi Group (The Neogenic strata that havedeposited in tlae various basinsin Kinl<i area). The Kii Strait is situated in the vicinity of Lat. 380N, Long. 1350E.   The materials used for tliis work were collected by T. HABE and J. IToiGAwA.326 Kiyoshi SAwAIThe survey began on the 28th October and finished on the 4th November 1955, forthe purpose of making a research in the Åíhanatology and ecology of Mollusca.

Ekman-Lenz's Bottom Sampler wasemployed.    About 30cc. of surface material of each locality was screened with the 200 meskstandard sieve.    The populations of Foraminifera in the residues were counted. In order to getthe' outline of the fauna of this region, the distribution chart was made at first.    The percentage densities of species were shown on Table 2.Deposits of Foraminiferal Tests in the Kii Strait, Japan 327                    Distribution of foraminiferal tests    The composition of foraminiferal tests in this area is different from the otherbays or shallow seas in that the various elements take places together at almost allstations. The mixed fauna is divisible into the following 4 groups: pelagic forms,arenaceous forms, calcareotts imperÅíorate forms and ca!careous perforate forms.                       Pelagic foraminiferal forms    The distribution of the pelagic forms shows nearly the same tendency as thoseof the other bays in Japan.    The pelagic forms are !imited te the transitional zone between the bay and opensea waters. The fo!}owing 4 species are recogniged : Globigerina bulloides D'ORBiGNy,G. eggeri BHuMBLER, G infiata D'ORBiGNy and G. sp.. These species co;npose onlya small portion (59oi) of the population.    Gepera!ly speaking, the nurr}ber of pelagic forms increases toward the open seaarea. The greatest number of the tests of this species is found at the station 44.                     Arenaceous foraminiferal fornas    The distribution of the arenaceous forms is not iike the cases of Ago bay, Osakabay, and Hiuchi-Nada.    These forms occur almost over the whole area; the fo!!owing 5 species aredom2nant : Ammobaculites foliaceus (BRADy), accompanied wkh Yerneuilina advena(CusHM.AN), HaPioPhragmoides canariensis (D'ORBIGNy), Trochammina giobigerini-Soyva'xs (PARKER and JoNEs), and TeXtUtaria agglutinans D'ORmGNy.    Usually these forms are good indicators of the strong embayment character.However, the arenaceous forms altogether are only 79o! of the total in population.    Generally the number of arenaceus forms increases toward the interior part ofthe Strait.    This group is regarded to represent the embayment water.                     Imaperforate forarainÅíeral forms    This group occurs a!most everywhere in the area though !ew percentage (4.59oi)!n population and it is cornposed of only one famiiy, Miliolidae. The foilowing 5species are dominant species : Quineueloculina vttlgaris D'ORBiGNy, Q. lamarckia"aD'ORBiGNy, Massilina atveoliformis (MiLLETT), Sigmoilina arenaria (BRADy) andSck.lu?nbergesina alveolifor•mis (Bi ADy).    The number of this fauna increases toward the interior part of the Strait ingeneral. The greatest number is found in the vicinity of the Awaji Island.This group         Perforate foraminiferal formsis found at almost ali the stations, except those in the shore of Shikoku.s.328 Kiyosiii SAWAI   Table 2.

The dominant species (11) are as follows: Bolivina rob"sta (BRADy), NonionjaPontca AsANo, EIPI•tidium advenum (CusHMAN), Rotalia. beccari•i (LiNNAEus),Rotalia PaPiglosa BRADy, Cibicides refttggens (MoNTFoRT), Yirgulina sclicreibersianaCzJzEK, Robulus calear (LiNNAEus), Cibicides lobatulus (WA.i<LER and JAcoB),EIPk.idiu}u fax barbarense (NicoL), and Bulimina marginata D'ORBiGNy. These$pecies altogether are 8496 of the total in population. This group is the representa-tive of the foraminiferal composition of tliis area. Bolivina robusta (Brady) lspredominant, with a high precentage (169oi) in population; the greatest number ofthe tests of this species is found at the statioR 16.
