 six shouldered whorls; suture distinct, anal fasciole obscure, undu- 

 lated by the ends of the ribs, spirally striated; axial sculpture of (on 

 the last whorl 14 or 15) rounded ribs with wider interspaces, promi- 

 nent at the shoulder, crossing the whorls at the spire, obsolete on the 

 base; spiral sculpture of numerous narrow channeled grooves with 

 wider flattish interspaces, not nodulating the summits of the ribs; 

 on the spire the interspaces are more cordlike, six or seven between 

 the shoulder and the succeeding suture; aperture simple, inner lip 

 erased, canal short, straight. Height of shell, 10.5 ; of last whorl, 7 ;

 cords with narrower interspaces; on the last whorl the ribs are ob- 

 solete and the spiral sculpture feebler, flatter, and with occasional 

 intercalary smaller threads; anal fasciole and sulcus obscure, aper-
