Shell turrited-conical, smooth, shining, flesh-colwed, painted 

 with spiral pale lines articulated with purple ; whorls little convex, 

 separated by deep sutures, the last two-fifths the whole length, 

 obtusely angular ; aperture patulous, higher than wide, violaceous 

 inside, iridescent and smooth ; columella short, arcuate, terminat- 

 ing in a strong tooth. (Philippi.) 



The shell is steeple-shaped, smooth and shining, thin, much like 

 Tr. virgulatus in contour but very different in coloration. It con- 

 sists of 7 to 8 whorls, slightly convex, separated by a deep suture; the 

 last is over two-fifths the total length, and at the beginning is in- 

 distinctly angular ; the base is strongly elevated ; the aperture is 

 somewhat widened, higher than broad, rounded, the columella very 

 short, curved, ending in a strong tooth. Upon a flesh-colored ground 

 there are (on the upper surface) 5 whitish and purple-red articulated 

 spiral lines, half as wide as their inter-spaces ; on the base there are 

 nine or ten similar lines. The very smooth shining throat gives 

 blue-violet reflections. Alt. 13, diam. 9 mill.
