 above and below. White, with close vertical chocolate stripes, occa- 

 sionally broken into tessellation in places, and interrupted by tw< 

 narrow white spiral bands. Aperture narrow above, the outer li] 

 thin, interior of aperture very heavily calloused. Columella havinj 

 a strong, bifid spiral fold, with a single smo,ll parietal fold above ii

In this species the spiral grooves are deeper and more evenl; 

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

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

 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.
