ON MOLLUSCA OP THE WEST COAST OF NORTH AMERICA. 205 



of similar differences on the flora and distribution of land shells in the same 

 latitudes. The work therefore is extremely disappointing from its very ex- 

 cellence, as it shows how prepared the author was to fill up the gaps which 

 are to us the most perplexing ; but which his early death has left to be sup- 

 plied by other, we fear less trustworthy hands. 



Several valuable donations of shells, with the localities added by Mr. Hinds, 

 are preserved in the British Museum. The new species described are as 

 follow, so far as relates to the fauna of West N. America. The pages and 

 numbers, with the plates and figures, refer to the Zool. Sulph. ; but the 

 references are also added to the Proc. Zool. Soc. and the Ann. Nat. Hist.
