Cyprina Islandica Lamarck. Plate XXVIII, iig. 201. (p. 508.) 



Aiiimaux sans Vert., ed. ii, vol. vi, p. 290 ; Gould, luvcvfc., ed. i, p. 82 ; ed. ii, p. 443. 

 Venus Islandica Liune, Syst. Nat., ed. xii, p. li:U. 



Eastern end of Long Island to the Arctic Ocean ; on the nortliern 

 Enropean 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 fiithoms ; Bay of Fnndy, G to 90 fath- 

 oms ; Saint George's Bank, 45 fatlioms; and Gulf of Saint Lawrence. 

 Montauk, Long Island (S.Smith). Fossil in 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.

 (Cones). Fossil in the Post-Pliocene of South Carolina. 



Serripes Gronlandicus Beck [Aphrodite Groiilandica Stimpsou ; Gould, 

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

 ton, Connecticut, by Linsley, but has not 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, JMaine, 8 to ;;0 fathoms, rare, (A. E. V.).
