GLESSULA, NON-PENINSULAR INDIA TO INDO-CHINA. 99 



Ponsee, Yunnan, type loc., and near Bhamo. 



Stenogyra (Glessula) blanfordiana G. NEVILL, J. A. S. B. 

 1877, p. 26; 1881, vol. 50, p. 138, pi. 5, f. 12. 



This species closely resembles Glessula peguensis Blanford, 

 but is less convex, that is, more slender, and a thicker texture ; 

 it can also be easily distinguished by the characteristic, 

 crowded, well-developed, nearly perpendicular, longitudinal 

 striation, varying slightly in direction on each whorl, much 

 as in many species of Pomatias. The columella also is 

 peculiar. Type in Indian Museum, Calcutta." (Nevill.) 



75. G. PEGUENSIS (Blanford). PI. 13, figs. 12. 



"Shell oblong-ovate, rather solid, dark reddish brown, 

 horny, marked with distinct and regular impressed lines. 

 Spire convexly conical; apex obtuse; suture impressed, sub- 

 crenulate. Whorls 6^2, slightly convex; the last ascending 

 a little towards the mouth, and exceeding % of the shell in 

 length. Aperture vertical, truncately semicircular; peris- 

 tome obtuse, slightly thickened; margins joined by a callus; 

 columella very much curved, projecting forward at the 

 base, subvertically truncated within the peristome. Length 

 7, diam. 3.5, length of aperture 2.75 mm." (W. T. Blanf.)

 THEOBALD & STOLICZKA, J. A. S. B. vol. 41, 1872, p. 334.- 

 S. (G.) peguensis NEVILL, Handlist, p. 171. 



The specimen figured exceeds Blanford 's measurements 

 slightly ; length 8.9, diam. 3.9, longest axis of aperture 3 mm., 

 whorls 6%. The apex is smooth ; the rest of the shell is 

 closely and rather deeply but irregularly striate, and very 

 glossy. 



"A pretty little species, darker in color than any of its 

 allies, except perhaps A. gemma Bens., and easily distin- 

 guished from all, by the columella being more arcuate, also by 

 its more acuminate spire and blunter apex, and its much 

 stronger sculpture." (Blanf.)
