sandy bottoms, off Cape Cod and south of Martha’s Vineyard, while 
our littoral variety seems to have its counterpart on the northern 
coasts of Norway and Finmark,. : 
B. Donovani, hitherto not known south of the Grand Bank, Stimp- 
son and many others have regarded as a valid species. Jeffreys 
(Annals and Mag. Nat. Hist., 1880) considers it a variety of B. gla- 
ciale Linné, but he refers Gould’s shell to B. Grénlandicum = B. 
ceyaneum. Metis, R. St. Lawrence! (coll. Dawson.) 
According to Dr. Stimpson, Gould had included, in his collection, 
three distinct species under the name ot B. ciliatum, one of which 
is the true eddiatwm (Fabr.), but his description and the figure (in 
ed. I) apply more particularly to B. Gouldii V. The new figure, 
in ed, II, represents a different form. 
Two northern species, not previously supposed to occur so far 
south, have been dredged by us, living, in considerable numbers, in 
the New England region, viz: B. cyanewmn and B. tenue. 
All these species were described in detail by Dr. Wm. Stimpson, 
in his Review of the Northern Buccinums,* in 1865. 
The following additional species, apparently undescribed, occurred 
in deep water off Martha’s Vineyard. 
Buccinum Sandersoni Verrill, sp. nov. 
PLATE LVIII, Figure 9. 
Shell elongated, brownish, translucent, rather thin and delicate, 
with a high spire; well-impressed suture; strongly convex, obliquely 
ribbed and strongly spirally sculptured whorls; a large smooth, 
mammillary nucleus; a small aperture; and a short, nearly straight 
columella. 
Whorls, in our largest example, seven, a little flattened below the 
suture, strongly convex in the middle; the penultimate whorl with 
about 18, broadly convex, curved ribs or undulations, strongly 
excurved at the middle of the whorl; on the body-whorl the ribs are 
less prominent and fade out below the middle; on the three upper 
whorls they are absent. ‘The spiral sculpture, on the lower whorls, 
consists of prominent, narrow, rounded cinguli, unequal in size and 
separated by narrow grooves; usually there are three or four smaller 
and lower cinguli, between two of the larger ones, and sometimes a 
narrow groove appears on the larger ridges, dividing them into two;
