loss common northward. It is the most common species sonth of Cape 

 Cod, in moderate depths (18 to 30 fathoms), where it is nsually unac- 

 companied by any other species, and occurs of large size and typical 

 form. We took it off Gay Head, Martha's Vineyard, 18 to 29 fathoms, 

 in 1871, 1880, 1881 ; off Block Island, 20 to 28 fathoms, 1874, 1880 ; east- 

 ern end of Long- Island Sound, 1874; Massachusetts Bay, 8 to 29 ftith- 

 oms, 1873, 1877, 1878, 1879 ; Cape Cod Bay, and off' Cape Cod, 15 to 34 

 fathoms, 1879 ; Casco Bay, 1873 ; Eastport, Me., and Bay of Fundy, 10 

 to 50 fathoms, 1870, 1872 ; Halifax harbor, 20 fathoms, and off" Halifax 

 120 miles, 190 fathoms, 1877. Messrs. Smith and Harger, on the " Bache," 

 in 1872, took it at various localities on George's and Le Have Banks, 

 in 25 to GO fathoms. Oft" Martha's Vineyard, 104 miles, 3C8 fathoms,

 This species is found from off' Martha's Vineyard to Labrador! It is 

 not uncommon in Eastport harbor and the Bay of Fundy, where I 

 dredged it in 1864, 18G5, 1868, 1870, in 15 to 80 fathoms. By the U. S. 

 Fish Com. it has been dredged in Halifax harbor in 20 to 25 fathoms, 

 1877 ; George's Bank, 45 fathoms, 1872 -, Gulf of Maine, at Cashe's Ledge, 

 30 to 40 fathoms, 1874; off' Cape Ann, 38 to 40 fathoms, 1874; Casco 

 Bay, 1873 ; Massachusetts Bay, 31 to 48 fathoms, 1877, 1879 ; off' Cape 

 Cod, 30 to 122 fathoms, 1879; off Chatham, Mass., 16 fathoms, 1881. 



Off Martha's Vineyard, 255 fathoms, 1881. It appears to occur on 

 the coast of Greenland. 



Whether it can be identified accuratelj' with any European species is 

 doubtful. Many writers have considered it identical with B. pyramid- 

 alis (Strom). But the shell figured under that name by Prof. G. O. Sars 

 appears to be quite different.

This shell extends from off Martha's Vineyard, in 126 and 312 fathoms 

 (stations 877, 947), north to Nova Scotia and Labrador; and probably
