638 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



Vineyard Sound, 3 to 10 fathoms ; near New Haven. Sew Bedford, 

 Mass., and Charleston, S. O. (Stimpson). Staten Island ; Greenport 

 and Huntington, Long Island, low water to 3 fathoms, (S. Smith). 

 Beaufort, N. C. (Coues). Fossil in the Post-Pliocene of South Carolina. 

 PlEurotoma bicarinatum Couthouy. Plate XXI", fig. 106. (p. 418.)

Stonington, Conn. (Linsley). Vineyard Sound, 6 to 12 fathoms, rare ; 

 Massachusetts Bay; Bay of Fundy. 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 73°, 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 occurs 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. S. 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 distinct from the European, and adopted the name 

 undulatum for it. 

 Neptunea curta Verrill.
