T. elongato-ovata, acumiuata, solidiuscula, laevis, fulvida, albido strigata; 

 spira clevata, peracuta, anfr. septem ultimo trientes duos long, vix aequante : 

 aper tura tricntem long, adequans, subovata ; labro albo antice revoluto, sub-

 with unequal longitudinal strigae of white shading into each other, 

 white at suture ; spire acute, elongated ; whorls seven, moderately 

 convex, the last not quite two thirds the length of the shell ; aper- 

 ture less than half the length of the shell, obliquely subovate, lip soon 

 becoming revolute, broadly so in front, rising, a little narrowed, by 

 a somewhat abrupt curve upon the columella, and expanding again 

 as it rises, until the two extremities of the lip nearly meet ; the 

 columellar portion stands off* from the body whorl, displaying a large 

 umbilical fissure ; lip white, with a brown submargin at the point of

 much larger and thicker.

Shell minute, delicate, thin, elongated, laterally compressed, so 

 that the two sides are parallel ; dorsal aspect a long, narrow oval ; 

 lateral aspect low triangular ; apex at about the anterior third, 

 acute, antrorse ; surface with delicate lines of growth, and a few
