228 PEOCEEDINGS OF THE MALACOLOGICAL SOCIETY. 



.53. Tkochits (Lamprostoma) incrassatus, Lam. A common but 

 variable Eastern species. 



54. Tkochtjs (Lamprostoma) pijstulosus, Pbil. Seemingly a well- 

 marked shell, but Pilsbry (Man. Conch., ser. i, vol. xi, p. 30) with 

 some doubt allies it to T. calcaratus, Souv., from New Caledonia. 



55. Trochus (Tectus) obeliscus, Gmel. More widely known as 

 T. pyramis, Born (or Phil.). A very abundant species throughout the 

 Eastern tropical area. 



56. MoNODONTA LABio, L. Recorded from African, Indian, Chinese, 

 and Japanese coasts, and not uncommonly in most of the Polynesian 

 islands. 



57. Clanculus stigmatarius, A. Ad. 



58. Clancttlus tjnedo, A. Ad. This and the preceding species 

 occur together. We defer to Pilsbry's acute differentiation (Man. 

 Conch., ser. i, vol. x, pp. 69-71) as regards their distinctness. The 

 former has the wider distribution, the latter being almost confined to 

 the New Caledonian Archipelago. 



59. Patella testtjbinaria, L. A handsome Patella, which ranges 

 from the Philippines southward. 



60. Patella oculata, Meusch. Two examples. "We consider this 

 to be a somewhat obscure species. 



61. AcM^A (Patelloidea) saccharina, L. Fine examples. Not 

 uncommon throughout the Eastern area. 



62. SiPHONARiA ExiGTjA, Shy. A large species, marked by many, 

 radiating, white ribs. Its range is from the Philippines south- 

 westward. 



63. PLAcUiSrA PLACEN^TA, L. This, the Placenta orhicularis, Retz, is 

 especially frequent in Chinese waters. 



64. Meleagrina margaritieera, L. Distributed throughout the 

 Eastern region, in abundance. 



65. Amitsium pleuronectes, L. China is its headquarters. It is 

 the type of the genus Amusium, Bolten. 



66. Tellina eoliacea, L. Very fine examples of this beautiful 

 species, which is distributed from the Philippines south-westward. 



67. Mactea ANTiauATA, Spongier. Another fine mollusc, which has 

 its headquarters in the Philippines. 



68. Tapes Indica, Hanley. Not infrequent on the shores of India 

 proper (Abercrombie, Townsend, etc.). 



69. SiLiauA RADiATA, L. A beautiful and common species. The 

 Pelecypoda in the present collection are very insignificant in number 

 and interest, as compared with the Gastropoda.
