mira. These specimens are apparently the same as those com- 

 mented on by Mr. Ancey and those described by Heude as 

 Stenogyra fuchsiana, and differ from mira in the larger apex, 

 perforate axis, larger aperture, etc. 



Heude 's type (pi. 2, figs. 21, 22) measured 27x9 mm., with 

 8 whorls, and was from Pao-k'ing-fu, in southern Hunan, col- 

 lected by Fuchs. 



6&. Var. megeanus Ancey differs from the type by the 

 smaller size, shorter form and number of whorls. Length 25, 

 diam. 8, alt. aperture 7 mm., whorls 9 (Ancey).

7. T. PERMIRUS (Ancey). PI. 2, figs. 15, 16, 17. 



Shell solid, imperforate, elongate-turrite, with an oily gloss. 

 Spire regularly conic-tapering, the apex obtuse. "Whorls 10, 

 regularly increasing, parted by an impressed suture, the first 

 smooth, the rest ornamented by obsolete striae more distinct 

 at the suture. Last whorl hardly ascending, tapering below. 

 Aperture distinctly oblique, irregularly oval, narrowed at 

 both ends, angular above. Columella thick, a little arcuate, 

 then twisted-plicate, nearly vertically truncate, and forming 

 an angle with the base. Lip thickened, obtuse, subpatulous, 

 the margins remote, joined by a strong and adnate callus. 

 Color greenish-corneous, the apex a little paler, peristome 

 white. Length 32, diam. 10, aperture 10 mm. high, 7 wide

This species especially approaches 8. mira Gredler of 

 Hunan, but the aperture is more ample, the columella less 

 arcuate, less abruptly truncate, etc. (Anc.).

Differs from the type by its more strongly longitudinally 

 striate or even plicate surface.
