This part is similar to the one published in 1879, consisting of a 

 report of the many collections received since that time. Some 27 

 species of Cephalopoda are recorded, including six new species. The 

 Gastropoda are ix'presented by 35 species, 12 of which are new. 

 Scaphapoda two species, and Pelecypoda 48 species, 10 being new to 

 science. The synonymy and bibliography is given in full and the 

 illustrations are excellent. The work is a valuable contribution to 

 American palaeontology. — C. W. J.
