Cyprina IstanpicaA Lamarck. Plate XXVIII, fig. 201. (p. 508.) 
Animanux sans Vert., ed. ii, vol. vi, p. 290; Gould, Invert, ed. i, p. 82; ed. ii, p. 443. 
Venus Islandica Linné, Syst. Nat., ed. xii, p. 1131. 
Eastern end of Long Island to the Arctic Ocean; on the northern 
European coasts southward to England. Off Block Island, 29 fathoms, 
sandy mud; off Gay Head, Martha’s Vineyard, 19 fathoms, soft mud ; 
common in Casco Bay, 10 to 80 fathoms; Bay of Fundy, 6 to 90 fath- 
oms; Saint George’s Bank, 45 fathoms; and Gulf of Saint Lawrence. 
Montauk, Long Island (8. Smith). Fossilin the Post-Pliocene of Scan- 
dinavia, Scotland, England, Sicily, and other parts of Europe. In 
North America it appears not to have been found fossil hitherto, and it 
must, therefore, be rare in our northern Post-Pliocene or glacial de- 
posits, if not altogether absent.

ticut, rare ; Buzzard’s Bay and Vineyard Sound, £to12 fathoms, common ; 
very common in Massachusetts Bay, Casco Bay, Bay of Fundy, and 
Gulf of Saint Lawrence, 2 to 80 fathoms. Labrador, south of Straits of 
Belle Isle (Packard). Huntington, Gardiner’s and Peconic Bays, Long 
Island (S. Smith.) Off New London, Connecticut, (coll. T. M. Prudden).

Florida and northern shores of the Gulf of Mexico to Cape Cod; 
rare and local farther north. Common in Long Island Sound, Buzzard’s 
Bay, Vineyard Sound, and about Nantucket. Dartmouth Lakes, Hal- 
ifax, Nova Scotia (Willis, t. Gould). West Florida (Jewett). Fort Macon 
(Coues). Fossil in the Post-Pliocene of South Carolina. 
Serripes Gronlandicus Beck (Aphrodite Grénlandica Stimpson ; Gould, 
Invert., ed. ii, p. 144, fig. 454). This species wasrecorded as from Stoning- 
ton, Connecticut, by Linsley, but hasnot since been found south of Cape 
Cod, and must, therefore, be regarded as a doubtful inhabitant of our 
waters. It occurs from Massachusetts Bay to the Arctic Ocean, but is 
rare south of the Gulf of Saint Lawrence and Labrador. Casco Bay 
and Mount Desert, Maine, 8 to 30 fathoms, rare, (A. H. V.).
