[<;r.:'>] INVERTEBRATE ANIMALS OF VINEYARD SOUND, ETC. 



Sound j Buzzard's Bay. Very abundant north of Massachusetts I 

 in Casco Bay, Bay of Fundy, Labrador, etc. Staten Island and Long 

 Island (S. Smith). 



Fossil in the Post-Pliocene of northern Great Britain and Scandi- 

 navia. 



Lacuna neritoidea Gould.

This species is a very doubtful inhabitant of this region, having been 

 recorded by no one except Linsley, 1845, who reports it from Long 

 Island Sound (Oyster Kiver and Long Beach, Stratford, Connecticut). 

 I have never been able to find it in the same region, nor has any one else 

 had better success. Linsley's specimens may have been incorrectly 

 named. It occurs in Massachusetts Bay ; at Cape Elizabeth, Casco Bay ; 

 Grand Menan Island, etc. ; northward to Greenland $ and on the northern 

 shore of Europe.

The tentacles in this species are rather short, scarcely exceeding the 

 breadth of the head, slightly tapering, blunt ; the eyes are on low prom- 

 inences on the outer side of the bases of the tentacles ; rostrum large, 

 stout, transversely wrinkled, longer than the tentacles, tapering some- 

 what, but divided at the end by a deep emargination into two rounded 

 lobes, which are often somewhat expanded. Foot short and broad, sub- 

 truncate anteriorly, with the angles broad and but little produced, pos- 

 terior end broadly rounded. 



New Jersey to Nova Scotia and Gulf of Saint Lawrence. Abundant 

 along the brackish and muddy shores of Long Island Sound, Buzzard's 

 Bay, Vineyard Sound, Massachusetts Bay, Casco Bay, and Bay of 

 Fundy. 



It is not confined to brackish waters, but often occurs also on the 

 ocean shores, under stones between tides.
