 Bela Sarsii Veniii. 



Verrill, these Transactions, vol. v, p. 484, 1881. 



Bush, Proc. U. S. Nat. Mus., vol. vi, p. 237, pi. 9, fig. 8, 1883. 



Miss Bush has recorded this species from Labrador, at Forteau 

 Bay, L'anse a_u Loup, in 10 to 20 fathoms, and from Murray Bay, 

 mouth of the St. Lawrence River, 



These specimens agree well with those fi"om the Norwegian coast. 



This species is closely allied to £. hnjyressa Morch, from Spitz- 

 bersren. 



Pleurotomella bandella (Daii). 



Pleurotoma (Mangilia) bandella Dall, op. cit., p. 59, 1881.

After the earlier pages of this article had been printed I had an 

 opportunity to compare our species of Pleurotomidse with those 

 obtained by the Blake Expedition in the West Indian seas, and now 

 in the hands of Mr. Dall, who has described most of them, and who 

 kindly aided me in making the comparisons. 



The species described above as P. Diomedece appears, on com- 

 parison of the type-specimens, to be identical with P. bandella 

 Dall. The other species described by Mr. Dall all appear to be 

 distinct from those described by me, but our P. Emertoni (p. 154) 

 is identical with one of his undescribed species. 



Mangilia cerina (Kurtz and Stimpson) Verrill. 

 These Transactions, vol. v, p. 488, fig. 1, 1881.

 very slender, with conspicuous black eyes close to the ends, the tips 

 extending slightly beyond the eyes, as small papilhe. Head small.
