This species resembles Strepsidura tippana Con.,^ a species 

 which was afterwards placed by the same author in his genus 

 Hercorhynchus.^ The New Jersey shell differs from this form, 

 however, in the absence oi spiral markings.

Description. — Shell subglo'bose, with a short anterior beak, 

 spire moderately elevated, volutions six or more in number. The 

 dimensions of a large, somewhat imperfect and distorted internal 

 cast are: total height, 45 mm.; greatest width after correcting 

 for the distortion, about 37 mm. Volutions of the spire marked 

 by rather broad, vertical nodes which reach nearly from suture 

 tO' suture, their greatest prominence being somewhat above the 

 mid-height; body volution marked by similar nodes which are 

 continued anteriorly, dying out about two-thirds of the distance 

 from the suture to the anterior extremity, these nodes are 

 broad, separated by about equally broad depressions, and are 

 most prominent a little below the suture. Surface of the shell 

 marked throughout by moderately coarse, depressed, revolving 

 ribs, the distance from center to center of the larger ones upon. 

 the example whose dimensions are given above being about 

 2 mm. 



Remarks.— Th.ia species has not been met with commonly in 

 the New Jersey collections. The specimen here illustrated and
