 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.

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



Serripes Groiilandicm Beck (Aphrodite Gronlandica Stimpson ; Gould, 

 Invert., ed. ii, p. 144, fig. 454). This species wasrecorded as from Storiing- 

 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, Maine, 8 to 30 fathoms, rare, (A. E. V.).
