INVERTEBRATE ANIMALS OF VINEYARD SOUND, ETC. 655 



6 to 25 fathoms; Bay of Fundy, 4 to 20 fatboins. Fossil iu the Post- 

 Plioceue of Canada. This species is usually brownish or chestnut-color, 

 but is also frequently white. 



Bissoa ehurnea Stimpson, has been recorded (as Rissoella{f) ehurnea) 

 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 Massachnsetts 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, 1 have seen a shell closely resembling 

 Rissoa latior Stimpson, (M. and Adams, sp.), if not identical with it.

Shell white, short, 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 strisB of growth; a slightly impressed revolving line just below 

 the suture. Aperture large and broad. Length about .15 of an inch ; 

 breadth, .12.

 from off New Jersey, in 35 fathoms (Captain Geduey); and Saint George's 

 Bank, north latitude 41° 25', west longitude 65° 50', 3", in 60 fathoms, 

 (S. I. Smith).
