TJic Marine Mollusca of Bombay. 19 



species, known to have their metropoHs in the Philippine 

 Islands, or even in Japan and S. E. Australia, show, when 

 found to occur here; and, secondly, because several 

 interesting forms are endemic, or nearly so. 



Such are — 



Cyllene fuscata (Ad.), 



ZizypJiimcs scobinatiis (Ad.), 



Fairbankia Bonibayajia (W. Blanf ), 



Nerita oryzarum (Recluz), 



Comis lentiginosus (Reeve), 

 and, so far as is known at present, the new species to be 

 described at the present opportunity. 



A very few would appear to be outljing forms, almost, if not 

 quite, identical with British or Mediterranean species, e.g : 



CalyptrcBa Sinensis (L.) van 



Area lactea (L.) var. 



Cylichna cylindracca (Pennant). 



Amongst the specimens found on the open sea shore are 

 the following brackish or fresh water shells. These, for the 

 most part, we do not include in our Catalogue, since they 

 should be classed more with the Fluviatile Mollusca than 

 with Marine, as 



Neritina crepidularia (Lam.). 



Potamides {Tympaiiotonos) fluviatilis (P. & M.). 



Telescopiuvi fusciim (Schum.). 



LynmcEa pingiiis (Dohrn). 



Melania tuberculata (Moll.). 



Auricula J iidcB (Linn.). 



Cassidula nucleus (Mart.). 



Ampullaria nux (Reeve). 



„ dolioides (Reeve). 



Of these, the two first mentioned are especially abundant. 

 The following twenty shells, described as more or less 

 endemic in Bombay, we have not, so far, been able to find
