Figures of Nondescript Shells; Table 2, PI. 43. 
Shell light brown, encircled on the body whorl by nine to fifteen 
revolving ribs, which are not flattened on the top, usually three of these 
ribs are visible on the spire whorls. (Tryon, Manual of Conchology.) 
Shell with posterior part of whorl rounded, making a smaller angle 
with the suture; often with more or less strong ribs above the first prom¬ 
inent rib. Ribs slender, more equal, less elevated, not flattened on top; 
interspaces not channeled, strongly grooved, often with quite prominent 
intercalated ribs. Aperture purple or livid; if partly white, the white is 
in the channels corresponding to the ribs, with the interspaces purple. 
Siphonal fasciole long and slender, usually nearly obsolete, sometimes 
quite so. Canal curved more or less strongly to the left of the aperture. 
Outer margin lighter than the throat. (Dali.) Length, 75-150 mm.

colored; the shell short-fusiform, periostracum inconspicuous; aperture 
shorter than the spire, the outer lip thickened and internally lirate; the
