[655] INVERTEBRATE ANIMALS OF VINEYARD SOUND, ETC. 361 
6 to 25 fathoms; Bay of Fundy, 4to 20 fathoms. Fossil in the Post- 
Pliocene of Canada. This species is usually brownish or chestnut-color, 
but is also frequently white. 
Rissoa eburnea Stimpson, has been recorded (as Rissoella (?) eburnea) 
by Dr. G. H. Perkins, from Long Island Sound, near New Haven, but 
I have seen no undoubted shells of this species from any locality south 
of Massachusetts Bay. The shell referred to by Dr. Perkins was beach- 
worn, and may have been some other species. The figure given in the 
second edition of Gould’s Invertebrata (fig. 564, p. 297), does not rep- 
resent this species. See the figure in Stimpson’s Shells of New England, 
Plate 1, figs. 1, la. This shell appears to be a Jeffreysia. 
From Huntington, Long Island, I have seen a shell closely resembling 
Rissoa latior Stimpson, (M. and Adams, sp.), if not identical with it.

Long Island Sound to Greenland, Iceland, Spitzbergen, Scandinavia ; 
and northern and eastern coasts of Europe generally, to England and 
France. Near New Haven, Connecticut, common; Watch Hill, Rhode 
Island ; Cuttyhunk Island. Very common on allrocky shores in Massa- 
chusetts Bay, Casco Bay, and Bay of Fundy. Fossil in the Post-Pliocene 
of Scotland and Scandinavia. 
STYLIFER STIMPSONII Verrill. (p. 460.) 
American Journal of Science, vol. iii, pp. 210 and 283, 1872. 
Shell white, shorf, swollen, broad oval ; spire short, rapidly enlarging. 
Whorls four or five, the last one forming a large part of the shell; con- 
vex, rounded, with the suture impressed, surface smooth, or with very 
faint strie of growth; a slightly impressed revolving line just below 
the suture. Aperture large and broad. Length about .15 of an inch ; 
breadth, .12. 
Parasitic on the dorsal surface of Strongylocentrotus Drébachiensis, 
from off New Jersey, in 35 fathoms (Captain Gedney); and Saint George’s 
Bank, north latitude 41° 25’, west longitude 65° 50’, 3”, in 60 fathcms, 
(8. I. Smith).

Vineyard Sound to Beaufort, North Carolina. In Vineyard Sound it is 
not uncommon on Thyone Briareus, in 4 to 10 fathoms. Buzzard’s Bay 
(Stimpson).
