Shell solid, oval, Avith conical, acute spire and obese body-whorl. 

 Surface spirally grooved throughout with impressed spirals, the

 above and below. White, with c/ose vertical chocolate stripes, occa- 

 sionally broken into tessellation in places, and interrupted by two 

 narrow white spiral bands. Aperture narrow above, the outer lip 

 thin, interior of aperture very heavily calloused. Columella having 

 a strong, bifid spiral fold, with a single small parietal fold above it,

In this species the spiral grooves are deeper and more evenly 

 spaced than in the next ; the color-pattern, even when most inter- 

 rupted, consists of solid, dark stripes or checkers; and the parietal 

 fold is single and deep-seated. 



Mr. Smith considers Reeve's T. coccinata a variety, and S. affinis 

 A. Ad., he regards as a small form of this species.
