*The species marked with an asterisk, seventeen in number, have never before been 

 reported from a locality so far north. 



t Mangelia levidensis (teste J. G. Cooper) has not previously been detected at a point so 

 far south ; it has heretofore been credited to " Straits of Fuca, W. T." vide Geo. Survey Cat. 

 1867, by J. G. C. 



t Tapes staminea and vars. were obtained at low water by digging from twelve to twenty 

 inches deep, and together with Macoma secta and M. nasuta, were found in the same holes. 



The Chitons above enumerated, have been compared with specimens recently (March, 

 1868) received labeled, from Dr. Carpenter of Montreal. 



No. 39, Acmsea scabra; elevated dark colored specimens of this species with the charac- 

 teristic sculpture sharply and well defined, were obtained in considerable numbers. Subse- 

 quently at Monterey I found occasional specimens displaying nearly the same elevation 

 and of the same color as those from Bodega.
