MOLLUSCA. 



The following list of Marine mollusca, which I have 

 collected in the Grulf of Manaar, includes (1) those which 

 were collected on the beach, all shells which were worn and 

 bore evidence of having been rolled in from a distance being 

 rejected, and only those which appeared to be fresh being 

 retained ; (2) those which were obtained by dredging, and 

 straining the contents of the dredge through sieves ; (3) those 

 which were collected on the coral reefs on clear days or at 

 low tide ; (4) those which were brought up from the pearl 

 banks and other places by native divers ; (5) those which 

 were obtained by examining the sweepings from the kottus 

 during the pearl fishery; (6) those which were found 

 attached to Algce and Gorgonice, or obtained by breaking up 

 coral blocks with a crowbar, and extracting the shells which 

 were buried in holes bored by the animals during life.
