Shell of moderate size, regularly tapered, conical, thin, semi-trans- 

 parent, smooth, shining, consisting of about twelve closely coiled, flat- 

 tened whorls, with the suture indistinct, defined by a thread of dark, 

 chestnut-brown, above and below which there is an indefinite band of 

 yellowish-white, gradually shading, towards the center of the whorls 

 into light yellow or brown, sometimes mingled with purple. The nu- 

 cleus is small, consisting of about three regularly coiled whorls of a 

 light purple or amethystine color. Base prominent, angulated, with 

 a moderately large and deep umbilicus, margined by a dark chestnut- 

 brown thread. Aperture nearly quadrangular, the angles being formed 

 at the termination of the dark threads, defining the base and the um- 

 bilical region, somewhat produced at the anterior angle, forming an 

 indistinct notch. Outer lip thin, with a dark chestnut-brown edge^ 

 inner lip regularly curved, slightly reflected over the umbilicus, with a 

 somewhat thickened, dark chestnut-brown edge; just back of this there 

 runs across the base, from within the umbilicus to the sutural thread, 

 a thread or streak of the same dark chestnut- brown color, and through- 

 oat the entire length of the shell, with the exception of the nucleus, 

 similarly colored streaks occur, crossing the whorls at irregular intervals. 

 In specimens somewhat eroded, fine but distinct lines of growth cross the 

 whorls at pretty regular intervals, and even in fresh specimens indica- 

 tions of them are occasionally seen. Operculum horny, very thin, light 

 yellow.
