It appears that Mr. Gaskoin was not acquainted with Phi- 

 lippi's species, which had not then reached the Cumingiaii Collec- 

 tion ; as he pronounced M. Ileigen's specimen to be new, and sug- 

 gested the specitic name m the Alazatlan Catalfgue. It would have 

 avoided a double synonymy, could the name tceniata have been re- 

 tained for the Samarang shell, and Mr. Gaskoiu's for this. The 

 Cape St. Lucas shells vary as above inlicated.

 diagnosis may be thus completed • —
