GASTEROPODA OF THE EOCENE MARLS. 239 
This shell differs from J. prisca Con., found associated with it, m its 
shorter and more ventricose form, shorter spire, and in the possession of two 
distinct columellar folds, instead of only one as in that species. The spiral 
lines are also somewhat more distant on the only specimens seen. The 
specimens agree very closely with Mr. Conrad’s figure cited above, differ- 
ing only in the very slightly greater elevation of the spire in the casts 
This, however, would naturally occur in the cast, although the number of 
volutions is usually less, as they are generally slightly longer. Mr. Con- 
rad’s specimen was doubtfully from Alabama, and preserved the shell sub- 
stance.

I have not seen this shell, nor any representative of it, so give Mr. 
Lea’s description below, and copy his figure. The description is as follows: 
“Shell cylindrical, truncate above, smooth; substance of the shell 
somewhat thick; spire short and truncate;- suture impressed; columella with 
one fold; whorls four; mouth narrow, about four-fifths the length of the 
shell; outer lip simple; length nearly 0.2, breadth 0.1, of aninch.” The local- 
ity assigned to the specimen is “Deal, New Jersey.” In Mr. Conrad’s list 
he gives it as from ‘“‘Claiborne,” Alabama, but I presume Mr. Lea under- 
stood full as well whence he obtained it, though no shells in that condition 
have been obtained from Deal so far as I know.
