OBSERVATIONS. 



Inhabits the southern coast. iSc/j/. It is common on 

 the coast of Rhode Island, and I found it fossil in the 

 same localities as the preceding species. Except in 

 its smaller size and rounded anterior margin, it ap- 

 pears not to differ from JV. nucleus, and is probably 

 identical with JV. obliqua of Say, described as a fossil 

 in Silliman^s Journal^ vol. II. p. 40.
