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. hella 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 TracJiytriton 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 tliree specimens marked as types in Mr. Grabb's collection, 

 one has a rather larger body volution than the others, and does not show 

 the cohimellar 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.
