274 Panama Shells. VENERIDJB. 



Cuming from the Philippine Islands : but there must be some 

 error in this statement, for in Feb. 1835, Mr. Cuming had not 

 made his collections in the Philippine Islands, and Mr. Sowerby, 

 in the original description in Proc. Zool. Soc. at that time, gave 

 the station and locality as we have quoted below. Conse- 

 quently the name C. biradiata must stand as a synonym of 

 C. squalida, and the shells from the Philippine Islands should 

 be named and described as a distinct species.
