 logue of the species of Amnicohi, Vivlpara, Bithi/nia, VaJvata, and Amptd-

 woodcuts, and contains the synonymy corrected from all the accessible types. 

 Dr. Stimpson is at present engaged in dissecting the moUuscs ; but none of 

 his investigations have yet been published. The following is a resume of the 

 West Coast species, from a proof kindly furnished by the author.
