"Shell small, rather short and wide, with a short, subacute 

 spire and almost 6 whorls; color ferruginous brown, faintly spiral- 

 ly zoned and lighter on the siphonal fasiole, pillar and throat 

 whitish, outer lip between the white of the throat and the margin 

 showing narrow spiral brown lines on a yellowish ground, whorls 

 with a tendency to a white, narrow peripheral line most evident 

 on the summits of the ribs; whorls excavated behind, somewhat 

 rounded before the periphery, the margin at the suture strongly 

 appressed with the whorl in front of it somewhat constricted; 

 suture distinct, hardly undulated, the spiral thread in front of it 

 slightly minutely imbricated; axially directed sculpture of finely 

 wrinkled silky incremental lines and (on the last whorl) 9 round- 

 ed ribs with rather wider interspaces, the ribs are obsolete near 

 the suture, on the early whorls, and on the base; spiral sculpture 

 of numerous flat strap-like threads with the interspaces much 

 narrower and sharply reticulated by the incremental sculpture 

 which rises in the interspaces nearly to the level of the tops of 

 the threads; the nucleus (lost) is small, the first 2 or 3 whorls 

 are more coarsely reticulate than the later ones; aperture elon-
