Solen viridis Say. This species has been recorded from the soutbern 
coast of New England by several writers (Stonington, Connecticut, Lins- 
ley; Rhode Island, Conrad), but L 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. Rare or local north of 
Casco Bay. Not observed in the Bay of Fundy. Common in Massa- 
chusetts Bay; Vineyard Sound; Great Egg Harbor, New Jersey, 
Comparatively rare in Long Island Sound, near New Haven; Fire 
Island Beach, Long Island (S. I. Smith). Coney Island, ete. (S. 
Smith). Rimouski, Gulf of Saint Lawrence, common, (Bell). Banks off 
Nova Scotia (Willis). The earliest name for this genus appears to be 
Stiliqua Mublfeldt, 1811. It was named Leguminaria by Schumacher in 
1817, and Machera by Gould, in 1841. The latter name is, moreover, 
preoccupied by Maechera 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, New Jersey, abundant. 
Fort Macon, North Carolina, very common (Coues). Alabama (Mighels). 
Fossil in the Post-Pliocene of Virginia, South Carolina, and Florida; in 
the Pliocene of South Carolina; and in the Miocene of North 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., 1801, p. 98) for a 
genus of Vermetide. 
This genus is widely different from the restricted genus Solecurtus
