Specimens of this species are recorded as having been dredged on the Le 

 Have Bank, N.S., in 45 fathoms, on the U.S. Fish Commission SS. Bache 

 in 1872, by Professor S. I. Smith and Mr. O. Harger. Other records for B. 

 cyaneum on the coast of Nova Scotia are as follows : " Off Cape Sable, N.S., 

 in 82 to 91 fathoms, fine compact sand, where it was common, and off 

 Halifax, in 100 fathoms " ; dredged by the SS. Speedwell, of the U.S. Fish 

 Commis'sion, in the summer of 1877. "It has often been brought in from 

 the banks off Nova Scotia " (Verrill, 1882; in Catalogue of Marine Mol- 

 lusca added to the Fauna of New England, etc , — in Trans. Conn. Acad. 

 Arts and Sc, vol. v, pp. 492 and 493). 



Sir J. W. Dawson records the occurrence of recent specimens, that he 

 identifies with this species, at Little Metis, Tadoussac, and Murray Bay ; 

 and Dall says that a living specimen of B. cyaneum was found on Labrador's 

 Reef, near Fort Chimo, Ungava Bay, by L. M. Turner in 1883. 



Sir J. W. Dawson says that B. cyaneum is abundant fossil in the Pleisto- 

 cene deposits at Riviere du Loup. 



In reference to the specific name of this shell, Professor Verrill makes the 

 following remarks. "Morcb, in adopting Grcenlandicum for this species, 

 simply took up a part of the polynomial name used by Chemnitz, which has 

 no claims to priority under the ordinary rules of binomial nomenclature- 

 "Stimpson, therefore, very properly rejected that name, as applied to this 

 species, and adopted the first distinctive binomial name given to it. 

 Jeffreys has followed Morch in using B. Gra^nlancllcum, and various other 

 European writers have followed the same usage, apparently without 

 sufficient reason. This has given rise to much confusion, because Grcen- 

 landicum has been extensively used for a very different species by Hancock, 

 Reeve, Stimpson, and other writers" (VerrilU, 1882; op. cit. p. 494).
