258 A. FE. Verrill— Mollusca of the New England Coast. 
Length, 3°"; greatest diameter, ‘8"". Some specimens are more

Verrill, Amer. Journ. Sci., xxii, p. 306, 1881; xxiv, p. 365, 1882; these Transac-

The animal of this shell, in alcohol, has a small and short anal 
tube, surrounded by small papille, and a very much larger incurrent 
orifice, occupying a ventral position and surrounded by numerous 
long and large tentacle-like papill ; the orifice for the foot is small; 
the edge of the mantle is bordered by very small papillae. There is 
a slender, translucent byssus. The hinge-ligament is strengthened 
by a distinct ossicle, placed lengthwise, more or less ovate in form, 
with the smaller end next to the hinge-teeth, and somewhat trun- 
cated. 
Additional specimens were taken at station i093, in 349 fathoms, 
1882 (two living), and at station 2079, in 75 fathoms, 1883 (one 
large dead shell).

A direct comparison of fossil specimens from the Miocene of Vir- 
ginia with a large series of recent specimens from various localities 
along our coast, both northern and southern, shows that the fossil
