"Defrancia Woodiana, Moller, from Greenland, has been considered as 

 identical with Bela harjndaria (Couthouy) by several authors. Moller's 

 description is of no value. I have seen no Greenland examples of B. 

 Itarpularia, and as it becomes decidedly rarer to the northward, on our coast, 

 its occurrence at Greenland seems to me doubtful. It becomes comparatively 

 rare in the Bay of Fundy and off Nova Scotia, where it is mostly replaced 

 by B. cancellata, B. scalaris, and other more arctic forms. A somewhat 

 similar shell, which I have identified as B. Woodiana, occurs on the coast of 

 Greenland, from whence I have specimens, and on the coast of Nova Scotia ; 

 this is probably the Greenland shell that has been taken for B. harpidaria 

 by various writers." The shells described and figured by Prof. G. 0. Sars 

 as B. harpularia and its variety, rosea, do not appear to me to be identical 

 with the true B. harpularia. " His shell has a different aperture, the 

 whorls are more decidedly and squarely shouldered, and the ribs fewer and 

 more distant. It is possibly the shell mentioned above as probably B. 

 Woodiana'' (Verrill, 1882; op. cit., pp. 474 & 475.)

i^ccording to Professor Verrill " this species ranges from Long Island 

 Sound to Nova Scotia, but is less common northward. It becomes compara- 

 tively rare in the Bay of Fundy and off Nova Scotia, where it is mostly 

 replaced by B. cancellata, B. scalaris and other more arctic forms." Pro- 

 fessor Veriill also says that it has been taken by the U. S. Fish Commission 

 at Eastport, Me., and in the Bay of Fundy, in from 10 to 50 fathoms in 

 1870 and 1872; at Halifax harbour, N.S., in 20 fathoms, and off Halifax, 

 190 fathoms, in 1877 ; and by Smith and Harger, on the Bache in 1872, on 

 the Le Have Bank, N.S. As already stated, the specimens dredged off 

 Grande Greve and formerly referred to B, scalaris by the writer, have been
