‘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-
