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 " CaUfomia " is used for both the temperate and the tropical 

 faunas. The following synonyms will be serviceable to the student ; —
