ON MOLLUSCA OF THE WEST COAST OF NORTH AMERICA. 5/O 



is given without authority; and the locality is probably erroneous. Various 

 other shells are scattered in the national collection, assigned either generally 

 to the West Coast or to special localities, which it has not been considered 

 needful to tabulate without confirmation.

 European authors not consulted in preparing the first Report. 



In the < Histoire Naturelle des Coquilles,' by L. A. G. Bosc, Paris, 1830, 

 the following species, not previously quoted, are assigned to the West Coast, 

 but without authority :

The following West Coast shells are named and figured by Dr. Gray in 

 ' Griffith's Edition of Cuvier's Animal Kingdom,' London, 1834. In some 

 instances there are also a few words of description :

In Woodward's most valuable ' Manual of the Mollusca,' London, 1851-6, 

 the following species are quoted as from " California " :

 Californian or W. Mexican coasts. Resembles P. caha~\. 



In the very valuable handbook of bivalves, ' Recent Shells, by S. Hanley, 

 London, 1842-56,' will be found either quoted or original diagnoses of all 

 West Coast species known to the learned, patient, and minutely exact com- 

 piler. As the locality-marks are simply transcripts, they are not here repeated, 

 especially as " California " is used for both the temperate and the tropical 

 faunas. The following synonyms will be serviceable to the student :
