the glaciale group ; they have the usual number of fine secondary 

 grooves upon thern, but the middle groove is often somewhat deeper 

 than the others. Aperture about two-fifths as long as the shell, 

 and rounded. The columellar lip is more incurved above than in 

 B. glaciale, and projects below to the level of the most projecting 

 part of the outer lip. The outer lip is somewhat thickened and 

 reflected, patulous, and broadly sinuated above about half-way 

 between the suture and the juncture of the carina. The perios- 

 traca is very thin, and not ciliated in any of the specimens which 

 I have seen. 



The dimensions of a typical example from the Banks of New- 

 foundland are, length, 2.7; breadth, 1.4 inch. 



Of this species I have seen several fine examples from the Banks 

 of Newfoundland in the collection of Dr. A. A. Gould, from one 

 of which the excellent figure in the " Invertebrata of Massachusetts" 

 was drawn. There are specimens from the same locality in the 

 Museum of the Smithsonian Institution, presented by the late 

 Gen. J. G. Totten, U. S. A. Moerch mentions the species in his 

 Greenland list. 



The B. Donovani is a species of very recent origin, and has 

 not, I believe, been found anywhere in a fossil state. 



It differs from B. glaciale in its elongated form, more con- 

 vex whorls, more concave columellar lip, and more convex 

 spiral ridges. The uncarinated variety may be distinguished 

 from B. undatum by the character of the spiral grooving, the dis. 

 tinction between the primary and secondary grooves being far 

 more strongly marked than in that species. 



The Buccinum Donovani in Mr. Bell's lists of the Shells of the 

 Gulf of St. Lawrence * is the Fusus Kroyeri of Moeller.

Shell very short, almost globose, thick ; spire short, conic ; whorls 

 five or six, slightly convex ; body-whorl more or less angulated, with 

 a carina at the middle, sometimes very strong, sometimes obsolete
