Dr. von Martens lias not been sufficiently careful in the se- 

 lection of names for the above large number of new species. 

 Helix conulus is preoccupied, we believe, for a Taheitian 

 species, and Mr. E. S. Morse has used the name milium for a 

 minute species inhabiting the State of Maine.

The lithographic plates which illustrate the species described 

 in this work, are some of the finest we have ever seen. The 

 species are, many of them, noble shells, evidently in splendid 

 preservation. Those figured in this volume are principally 

 of the genera Lucina, Oardita, Unio, Leda, Pectuneulus, Area. 



It is curious how the American types of Unio are repre- 

 sented among these European fossils, along with some belong- 

 ing to the still-existing European forms. PI. 37, figs. 6, 7, 8, 

 9, 10, exhibits shells which are eminently characteristic of ex- 

 isting American groups. The resemblance is wonderful.
