Eastern coast of the United States ; northward to Cape Cod and Nan-

 ceedings Boston Soc. Nat. History, vol. xiii, p. 117, figure, 1869 (variety). 

 Eastern coast of the United States ; northward to Vineyard Sound ; 

 southward to Florida, and the Gulf of Mexico ; not abundant north of 

 Cape Hatteras. In Vineyard Sound and Long Island Sound, found 

 sparingly in shallow water among eel-grass. New Bedford (Adams). 

 Lloyd's Harbor, Huntington, and Nortbport, Long Island (S. Smith) ,• 

 Egmont Key, Florida (Jewett). It has been found in the Pliocene and 

 Post-Pliocene of South Carolina. 



Some of Say's original specimens were from South Carolina, others 

 from Great Egg Harbor, New Jersey. At tbe latter locality I have also 

 collected among eel-grass, in shallow water, the variety described by 

 Dr. Perkins as If. fretensis, which is the most common form in all the 

 more northern localities. Specimens intermediate between these and the 

 ordinary southern forms are, however, of frecpient occurrence, and the 

 typical form also occurred in Vineyard Sound, with the variety.
