TellUna eupareia and Tellina atJwoa, of Ravenel arc list-names of 

 species found h}' him on Sullivans Island, Charleston Harbor, South 

 Carolina, and printed without tioure or description in the catalogue of 

 his collection, 1875. They have no standing and are unidentifiable, 

 but have been cited in the literature. Another Ravenelian name, 

 TcJlina omo'ia^ is cited by him as a synonym of T<Mina tenuis Saj^, by 

 which Tellina tenera Say was probably meant. 



SPECIES OF THE PACIFIC COAST OF NORTH AMERICA. 



Genus TELLINA Linnaeus. 



TELLINA CUMINGII Hanley, 1844.

Lower California to Tumbez, Peru. 



TELLINA (MERISCA) LAMELLATA Carpenter, 1857.

 so polished internally as to obscure the pallial line.

This is the Pacific coast analogue of Tellina Untea Conrad of the 

 Atlantic coast from which it differs in minor details, especiall}^ in being
