250 A. E. Verrill— Mollusca of the New England Coast. 
Bela Sarsii Verrill. 
Verrill, these Transactions, vol. v, p. 484, 1881. 
Bush, Proc. U. S. Nat. Mus., vol. vi, p. 237, pl. 9, fig. 8, 1883. 
Miss Bush has recorded this species from Labrador, at Forteau 
Bay, L’anse au Loup, in 10 to 20 fathoms, and from Murray Bay, 
mouth of the St. Lawrence River. 
These specimens agree well with those from the Norwegian coast. 
This species is closely allied to B. impressa Mirch, from Spitz- 
bergen. 
Pleurotomella bandella (Dall). 
Pleurotoma (Mangitia) bandella Dall, op. cit., p. 59, 1881. 
Pleurotomella Diomedec Verrill, this volume, p. 152, 1884. 
PLATE XXXI, FIGURES 5, 5a. 
After the earlier pages of this article had been printed I had an 
opportunity to compare our species of Pleurotomide 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. Diomedew 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. 
PLATE XXIX, FIGURES 16, lL6a. 
Animal translucent white, with flake-white specks on the foot and 
other parts. Foot short, truncate, or obtusely rounded in front, with 
the angles little or not at all prominent. Tentacles rather long, 
very slender, with conspicuous black eyes close to the ends, the tips 
extending slightly beyond the eyes, as small papillae. Head small. 
No operculum. 
Found living in Buzzard’s Bay, at Quisset, Mass., in 3-5 fathoms, 
Sept. 4, 1882.
