This species closely resembles T. macroptychia, but is 

 slightly smaller, with less conic spire and the whorls are not 

 as closely coiled. The name appears in Ancey's collection 

 and in specimens sent out by Baldwin, now in the Cooke col- 

 lection. With Ancey's type of T. macroptychia were three 

 of this 'Species. 



In an immature specimen with 4% whorls, the last whorl in 

 much narrower and tapers more towards the base than in 

 macroptychia and the columellar folds are not as strongly de- 

 veloped. The first embryonic whorl is very minutely and 

 faintly spirally striate. The parietal lamella is 0.21 mm. in 

 height. The upper columellar fold is 0.09, the lower 0.18 mm. 

 in height (fig. 10).

 a strong lens minutely striate, thin, diaphanous. Spire 

 ovately conic, apex somewhat obtuse. Suture simple, im-' 

 pressed. Whorls 5%, convex, increasing regularly and slowly, 

 the last broadly ovate, tapering towards the base. Aperture

 mella moderate, hardly oblique. Columella narrowly triangu- 

 lar, slightly tumid above, furnished with two very acute and
