 Cerithium Emersonii C. B. Adams, op. cit., p. 284, Plate 4, fig. 10, 1838 ; Gould,

Cape Cod to South Carolina. Vineyard Sound and Buzzard's Bay, 3

 species as identical with Ceritliium metula Loven, 1846, on the authority 

 of Danielssen. This appears to be an erroneous identification.

Turritella erosa Couthouy, reconled, with a mark of doubt, by Lin- 

 ley, as from the stonuich of a cod, olf Stonington, Conn., was perhaps
