オーストラリア周辺-インド洋-西太平洋海域で記載された現生タマキガイ科二枚貝のリストである。各種毎に原記載の文献学的引用, 模式標本の種類, 保管場所, 標本番号, 模式産地を記録した。太字で示された種名は命名規約上適格であり, 細字で示された種名は不適格である。ただし, 不適格な種名はすべて無効であるが, 適格な種名が常に有効であるとは限らない。たとえば, Pectunculus angasi CROSSE, 1880はMelaxinaea novaguineensis (ANGAS, 1879)の新参客観シノニムであるからANGASの種名が無効とならない限り, 適格ではあるが有効とはならない。本リストでは, すでに日本産の種名目録(松隈, 1979)でとりあげた種については省略したが, その後新しい情報を得た若干の種は再掲した。オーストラリア及びニュージーランドの化石種については, すでにFLEMING (1966), DARRAGH (1970), KEYES (1972)の新生代化石種のリストがあるが, 白亜紀の化石については未だ整理されていない。インド洋周辺及び東南アジア諸国の化石種も又未整理であるが, これらは日本南部の現生種並びに化石種の検討に緊急に必要なものであり, 早急にとりまとめることが望まれる。

瀬戸内海糸崎沖の細の洲で得たシラオガイとアケガイおよび伊予郡下灘で得たマツカゼガイのマルスダレガイ科3種について染色体数と核型を調べた。3種の精巣は焔乾法によって, またマツカゼガイの卵は押しつぶし法によって処理した。シラオガイの染色体数は2n=38, アケガイ, マツカゼガイでは2n=38, n=19であった。シラオガイでは材料が少なく, またアケガイでは染色体が小さく, 核型分析は困難であったが, 両種は中部あるいは次中部付着型染色体からなることが観察された。マツカゼガイでは14対の中部付着型と5対の次中部付着型の染色体からなることが観察された。

The growth of young snail and fecundity of adult snail were studied as a part of studies on mass-breeding of Oncomelania hupensis hupensis in the laboratory. The results were summarized as follows : 1. The growth of young snail fed with diatoms was better than that fed with baby meal. 2. The young snail fed with baby meal grows slowly without death than that fed with diatoms. 3. The fecundity of adult snail was increased by the supply of L-tryptophane or dextrose. 4. The fecundity of adult snail was reduced under the rearing condition where the water level was periodically changed from low to high and vice versa.

Miocene gastropod, Phanerolepida expansilabrum (KURODA) was collected from the Early Middle Miocene Nantaisan Volcanic Breccia (OTSUKI, 1975) in Ibaraki Prefecture with its operculum in life position. The species is characterized by its shagreen sculpture and slender form. Since no associated molluscan species with P. expansilabrum from the formation, other phanerolepid species from the Japanese formations as Miocene Bessho, Oidawara, Morozaki, Chichibumachi, Pliocene Shinzato, Tomiya, Nobori formations are associated with bathyal forms. However, the present occurrence of the species with operculum suggests that the formation mainly composed of andestic pyroclastics might have been deposited at the bathyal bottom in associated with andesite volcanic activity. Operculum of Phanerolepida expansilabrum is of paucispiral type (TAKI, 1950) with calcareous shell of Turbo type (COX, 1960), and very resembles that of modern species, P. transenna (WATSON) but slightly differs from these species of Pliocene Shinzato Formation, P. rehderi MACNEIL which has slightly elongated one. The Shinzato specimens are collected in isolated form and its variation of the external morphology was already mentioned earlier. The trend of morphological features and external sculptures from the Miocene to Recent is shown by the slender and rough sculpture in Miocene and swollen and fine sculpture in Recent. However, the morphological change of operculum of this genus through the geological age should be examined in future by more good materials.
