Shell small, short elliptical in outline, with a short pointed spire and 
proportionally long body volution; volutions probably about four, ventri- 
cose, largest above the middle and attenuate below; aperture large, elongate 
elliptical, widest above the middle and narrow below. Columella moder- 
ately strong, marked by two distinct and distant plications below the middle 
of the aperture; surface of the shell so far as can be seen on the inside of 
the cast of the outer volution in one of the type specimens, marked by a 
few spiral ridges and by distant vertical plications or folds, but which are 
not transmitted to the internal cast in any of the individuals seen. 
This shell has been of the type of V. bella Gabb, which it very much 
resembles, but is proportionally shorter and has a larger body volution. The 
casts may be very readily mistaken for those of Trachytriton atlanticus herein 
described, but can be distinguished by the expansion of the outer volution 
near the aperture, and by the lip extending backward upon the next volution 
in that one, which this never does, and also by the existence in this of the 
columellar folds, where the condition of preservation is such as to reveal 
them. Of the three specimens marked as types in Mr. Gabb’s collection, 
one has a rather larger body volution than the others, and does not show 
the columellar folds, while the columella itself is very slender, so that I am 
somewhat in doubt of its specific identity with the others. 
Formation and locality: In the blackish layers of the Lower Green 
Marls in New Jersey. Mr. Gabb does not mention the locality of this 
species, but from the character of the casts I think probably they came from 
Crosswicks Creek, near New Egypt, New Jersey.
