38 PALEONTOLOGY OF HEW JEliSBY. 



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 rajoid 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 forai is identical with Tuomey's T. BicJi- 

 ardsonn I 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 abotit 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.
