INVERTEBRATE ANIMALS OF VINEYARD SOUND, ETC. 683 



Cyprina IslandicA Lamarck. Plate XXVIII, fig. 201. (p. 508.) 



Animaux sans Vert., ed. ii, vol. vi, p. 290 ; Gould, Invert., ed. i, p. 82 ; ed. ii, p. 443. 

 Venus Islandica Linne, 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, 

 sanely 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 (S.Smith). Fossil in the Post-Pliocene of Scan-I 

 dinavia, Scotland, England, Sicily, and other parts of Europe. Ini 

 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. 



Oardium pinnulatum Conrad. Plate XXIX, fig. 209. (p. 505.) 



Journal Acad. Nat. Sciences, Philadelphia, ser. i. vol. vi, p. 260, Plate 11, fig. 3,

Long Island Sound to Southern Labrador. Near New Haven, Connec- 

 ticut, rare ; Buzzard's Bay and Vineyard Sound, 4 to 12 fathoms, common j 

 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). 



Fossil in the Post-Pliocene of New Brunswick.

 rad, op. cit., vol. vi, p. 259, Plate 10, figs. 5,6,7; Gould, Invert., ed. i, p. 91; 

 Liocardium Mortoni Stimpson, Check-List, p. 2, 1860; Gould, Invert., ed. ii, p. 

 143, fig. 453. 



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 Gronlandica Stimpson ; Gould, . 

 Invert., ed. ii,p. 144, fig. 454). This species was recorded as from Stouing- 

 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. E. V.).
