Solen viridis Say. This species has been recorded from the soutbern 

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

 ]ey : Ebode Island, Conrad), but 1 bave myself met with no autbentic 

 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. Eare or local north of 

 Casco Bay. Not observed in the Bay of Eundy. Common in Massa- 

 chusetts Bay 5 Vineyard Sound; Great Egg Harbor, New Jersey. 

 Comparatively rare in Long Island Sound, near New Haven 5 Fire 

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

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

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

 Siliqna Muhlfeldt, 1811. It was named Leguminaria by Schumacher in 

 1817, and Machcura by Gould, in 1841. The latter name is, moreover, 

 preoccupied by Maclicera Guvier, 1832.

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

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

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

 Fossil in the Post-Pliocene of Virginia, South Carolina, and Florida 5 in 

 the Pliocene of South Carolina ; and in the Miocene of ]Srorth and South 

 Carolina. 



Tlie name, SiUquaria Schumacher, 1817, adopted for this genus by 

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

 giere, 1791, and by Lamarck (see Syst. des Anira., 1801, p. 98) for a 

 genus of Vermetidcc. 



This genus is widely different from the restricted genus Solecurtus
