164 PALEONTOLOGY OF NEW JERSEY. 
the columellar lip are also somewhat remarkable, and would seem to ally 
the shell with the genus Cinulia Grey as nearly as with Solidwa. In facet, 
I have been strongly inclined to place it under that genus. The deflection 
of the upper margin of the outer half of the body whorl, by which a very 
much greater proportion of the preceding whorl is exposed on that side, is 
also a marked feature. 
Formation and locality: Dr. Morton gives only “‘New Jersey” as the 
locality. he specimens are from a brownish marl with green grains, and 
resembles that of the brown beds near Burlington and Mullica Hill, New 
Jersey, and I think are most probably from the former place. I have not 
seen any other specimens than the types, which are from the collection

Shell small, measuring only about half an inch in extreme length, form 
cylindrical, largest below, with nearly straight sides; spire deeply sunken 
in the cast; aperture large and the lip nearly straight on the sides, but 
gradually expanding below; columella curved; surface unknown. 
This small species is the only one yet found in the New Jersey Creta- 
ceous, and appears to be very rare, as the type specimen is the only one yet 
known, so far as I have been able to learn. Mr. Meek has recognized two 
species in the western Cretaceous, C. scitula and C. volvaria, the latter doubt- 
fully a Cylichna, and Dr. Shumard described three species from Texas, but 
none of them is nearly related to this one, in which the sides are so dis- 
tinctly flattened that it can not be well mistaken.
