38 PALEONTOLOGY OF NEW JERSEY. 
beak. Among the specimens of the species examined there is no evidence 
preserved showing the exact length of this part; but the evidence furnished 
is in favor of a short beak, as the rapid thinning of the cast at this part 
would not favor the opposite opinion. How much reason there may be for 
the assertion that the New Jersey form is identical with Tuomey’s 7. Rich- 
ardsonii 1 can not say, as I have not seen Dr. Tuomey’s type specimens, 
which were never figured; but there are casts of three or four species before 
me from New Jersey, some of which accord with his description more 
nearly in the “angle” of the volution being ‘‘rounded” than does this one. 
I would, therefore, rather retain this under Mr. Conrad’s name than refer it 
haphazard to that one. It is distinguished from all the other New Jersey 
species by the shorter form and greater angulation of the volution. 
Formation and locality: In the Lower Marl beds at Upper Freehold, 
New Jersey, from collections made by the State Geological Survey.

Shell of small size, pyriform in outline or subequal above and below 
the point of greatest diameter; volutions about three, very ventricose and 
rapidly increasing in size, full and rounded above and in the middle, but 
rapidly contracted below, forming a short, pointed beak, even in the cast; 
spire low-conical, sutures very marked in the cast; aperture large, semicir- 
cular on the outer margin and forming nearly or quite two-thirds of the 
entire length of the shell; columellar cavity very narrow, indicating a slen- 
der, straight beak; surface marked by closely arranged, spiral ridges, placed 
at nearly equal distances and numbering twelve or more on the body volu- 
tion; also by vertical lines, which, although faintly marked, appear to have 
been nearly the same distance apart as the spiral ridges or much more 
closely arranged, as seen on different individuals.
