344 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [638] 
Vineyard Sound, 3 to 10 fathoms; near New Haven. New Bedford, 
Mass., and Charleston, 8. ©. (Stimpson). Staten Island; Greenport 
and Huntington, Long Island, low water to 3 fathoms, (S. Smith). 
Beaufort, N. ©. (Coues). Fossil in the Post-Pliocene of South Carolina. 
PLEUROTOMA BICARINATUM Couthouy. Plate X XI, fig.106. (p- 418.) °

Stonington, Conn. (Linsley). Vineyard Sound, 6 to 12 fathoms, rare ; 
Massachusetts Bay; Bay of Fandy. This is a rare and imperfectly 
known species. I have never had opportunities to examine the living 
animal. : 
The generic relations of this and the two preceding shells are still 
doubtful.

Mouth of Vineyard Sound and off Gay Head, 6 to 19 fathoms. Off 
New Jersey, north latitude 40°, west longitude 75°, in 32 fathoms, 
sandy bottom, (Captain Gedney). 
Near Stonington, Conn. (Linsley); Montauk Point, Long Island, 
and Little Gull Island (S. Smith). Not common south of Cape Cod, 
except on the outer islands and in deep water; common in Massachu- 
setts Bay; and very abundant on the coast of Maine, and northward to 
Greenland. On the European coast it oceurs from Iceland and the 
North Cape to France, and from low water to 650 fathoms. In the Bay 
of Fundy it is abundant from above low-water mark to 100 fathoms. 
As a fossil it is common in the Post-Pliocene deposits of Maine, Can- 
ada, Labrador, and Great Britain. Mr. Desor obtained it from the Post- 
Pliocene formation of Nantucket Island. 
The ordinary American specimens from shallow water differ consider- 
ably in form from the typical European specimens, but the species is 
quite variable on both coasts, and I have examined large specimens 
from Saint George’s Bank and La Have Bank, dredged by Mr. 8. I. 
Smith, which differ very little from the common European form, and it 
is easy to form series connecting these with our common shore speci- 
mens. I am, therefore, unable to agree with Dr. Stimpson, who con- 
sidered our shell distinet from the European, and adopted the name 
undulatum for it.
