Aperture elongate-oval? Parietal wall covered by a moderately thick 

 callus; columella with two folds, of which the posterior, which is a 

 little anterior to the insertion of the columella, is much stronger than 

 the anterior, which is also much more oblique ; the outer lip is frac- 

 tured in the type and shows internal lirations. 



The type, U.S.N.M. No. 561602, was collected by Mr. Locklin at 

 the Pliocene deposits of North St. Petersburg, Fla. It has the nucleus 

 and 7 postnuclear whorls and measures: Length 5.1 mm., diameter 

 1.8 mm.
