INVERTEBRATE ANIMALS OF VINEYARD SOUND, ETC. 675 



Solen viridis Say. This species lias been recorded from the southern 

 coast of Xew England by several writers (Stonington, Connecticut, Lins- 

 ley ; Ehode Island, Conrad), but I have myself met with no authentic 

 New England specimens. It may, however, occur rarely and perhaps 

 accidentally. It is not uncommon on the outer beach at Great Egg 

 Harbor, New Jersey, and farther south, to Florida.

Cape Hatteras to Gulf of Saint Lawrence. Bare or local north of 

 Casco Bay. Xot observed in the Bay of Fundy. Common in Massa- 

 chusetts Bay; Vineyard Sound; Great Egg Harbor, Xew Jersey. 

 Comparatively rare in Long Island Sound, near Xew Haven ; Fire 

 Island Beach, Long Island (S. I. Smith). Coney Island, etc. (S. 

 Smith). Bimousld, Gulf of Saint Lawrence, common, (Bell). Banks off 

 Xova Scotia-(Willis). The earliest name for this genus appears to be 

 SiMqua Muhlfeldt, 1811. It was named Legumiiiaria'by Schumacher in 

 1817, and Machmra by Gould, in 184L The latter name is, moreover, 

 preoccupied by Maclicera Cuvier, 1832.

Caribbean Sea, West Indies, and Gulf of Mexico to Cape Cod. Simi- 

 lar if not identical species are found on the Pacific coast of Central 

 America, and on the west coast of Africa. Vineyard Sound and Buz- 

 zard's Bay, not uncommon ; Great Egg Harbor, Xew Jersey, abundant. 

 Fort Macon, Xorth Carolina, very common (Coues). Alabama (Mighels). 

 Fossil in the Post-Pliocene of Virginia, South Carolina, and Florida ; in I 

 the Pliocene of South Carolina ; and in the Miocene of Xorth and South 

 Carolina. 



The name, Siliquaria Schumacher, 1817, adopted for this genus by 

 several recent writers cannot be retained, because preoccupied by Bru- 

 giere, 1791, and by Lamarck (see Syst. des Anim., 1S01, p. 98) for a 

 genus of Vermetidce. 



This genus is widely different from the restricted genus SoUcurtus
