Massachusetts Bay to Labrador. Casco Bay, 6 to 50 fathoms; com- 
monin the Bay of Fundy from low-water mark to 80 fathoms. Linsley 
reports it, as /. corneus, from fish-stomachs at Stonington, Connecticut. 
In the Yale Museum are dead sbells of this species, which have been 
occupied by HLupaguri, found on Fire Island Beach, on the south side of 
Long Island, by Mr. S. L. Smith. It probably inhabits the deep water 
off Block Island. 
The dentition of this species is decidedly buccinoid. The central 
plates are transversely oblong, deeply concave above, with the lateral 
angles produced; below armed with three small, nearly equal, short teeth, 
the central one largest, beyond which, on each side, it is concave, the outer 
angles being a little prominent. The lateral plates are large, with an 
outer, very strong, curved tooth, and two much smaller, slightly curved 
ones near the inner end, the innermost being slightly the largest. 
The dentition agrees very closely with that of NV. antiqua, the type 
both of the genus Neptunea, Bolton, 1798, and Chrysodomus, Swainson, 
1840, but it is very different from that of Sipho Berniciensis (S. Island- 
icus Trosch.), which Troschel refers to the Faciolarida. The latter is 
evidently the type of a genus (Sipho) very distinct from Neptunea; but 
among the European species, gracilis, propingua, buccinata, and the true 
Islandica (as described by Jeffreys) are closely related to curta, and be- 
long to the genus Neptunea, in the family Buccinide.

Deep water off New London and Stonington, Connecticut, northward to 
the Gulfof Saint Lawrence. Eastof Block Island, 29 fathoms, sandy mud ; 
off Buzzard’s Bay, 25 fathoms; off Gay Head, 19 fathoms, mud, abun- 
dant and large; off Edgarton, 18 to 20 fathoms; Casco Bay, 10 to 40 
fathoms, common; Eastport, Maine, and Bay of Fundy, low water to 
100 fathoms (A. I. V.).. Near Saint George’s Bank, 40 to 150 fathoms ; 
east of Saint George’s Bank, 430 fathoms ; and off Halifax (S. I. Smith). 
The odontophore in this species is long and slender ; the dentition is 
bueccinoid. The middle plate is small, transversely oblong, concave 
above, below convex, with one very small central tooth ; lateral plates 
relatively large and strong, with a large, curved outer tooth, and a 
smaller bifid inner tooth, widely separated from the outer one. 
The peculiarities in the dentition of this species, in connection with 
the singular wooly or velvety epidermis, indicate that this species 
should form the type of a sub-genus, or perhaps evena distinct genus. 
For the group I would propose the name Neptunella.
