Eastern coast of the United States; northward to Vineyard Sound ; 
southward to Florida, andthe Gulfof Mexico; not abundant north of 
Cape Hatteras. In Vineyard Sound and Long Island Sound, found 
sparingly in shallow water among ecl-grass. New Bedford (Adams). 
Lloyd's Harbor, Huntington, and Northport, 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 the latter locality I have also 
collected among eel-grass, in shallow water, the variety described by 
Dr. Perkins as .V. 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 frequent occurrence, and the 
typical form also occurred in Vineyard Sound, with the variety.
