TJie Marine Mollusca of Bombay. 23 



p. 235 sqq., 1859), which was supplied by Mr. Sylvanus 

 Hanley, F.L.S., and one of the marine Gasteropoda only, by 

 the late Mr. A. W. Langdon {Joiirn. of Conch., Vol. I., p. 71 

 sqq., 1874). The principal contributors since those dates 

 towards the elucidation of the Fauna have been Messrs. 

 G. and H. Nevill, whose results have been mainly published 

 in XhQ Jonrn. Asiatic Soc. Bengal. 



Mr, Hanley's catalogue is much fuller than that of 

 Langdon, which latter does not include the Pelecypoda. 



Of the 265 Gasteropoda, 32 occur in our Bombay list, 

 and of the 130 Pelecypoda, 21. 



Too much weight should not, however, be given to these 

 proportionate figures, as in the Ceylon catalogue the smaller 

 genera were hardly taken count of, and, naturally, this 

 island being several degrees nearer the Equator than 

 Bombay, a more varied selection of tropical forms is to be 

 expected. For instance, 47 to 50 Conns are there reported, 

 26 Cyprcra, 9 Mnrex, and 1 1 Oliva. 



Considering that Bombay is one of the most cosmo- 

 politan centres in the world, it seems somewhat strange 

 that, as yet, no list of the Marine Mollusca has been issued. 

 Such a list, we believe, was some years ago contemplated by 

 the Rev, S. B. Fairbank, an American clergyman, who 

 collected largely at this port, but we have been unable, 

 unfortunately, to communicate with this gentleman. If we 

 except such well-known names as Mr. W. T. Blanford, 

 F.R.S., his brother, Mr. Henry F. Blanford, F.R.S., the 

 late Dr. F. Stoliczka, and Mr. Geoffrey Nevill, late of the 

 Indian Museum, Calcutta, we cannot find that any collector 

 has turned his attention to these shores. And the same 

 remarks would apply to almost the whole coast of Hin- 

 dustan proper. Ceylon, the Andaman Islands, and the 

 Mergui Archipelago off the coast of Tenasserim, have been 

 more assiduously investigated, the latter by Dr. John 

 Anderson, superintendent of the Indian Museum, Calcutta,
