and slightly flexuous on the last whorl ; spire turreted, with 

 very obtuse apex and excavated suture ; whorls six, scarcely 

 convex, the last one rounded at base ; aperture vertical, sub- 

 quadrilateral, with a much thickened white peristome ; col u ID ell a 

 broadly reflected, thickened, white, curved, forming an acute 

 tooth, with a well developed incised notch at its base.

"This species closely resembles Glessula peyuensis, Blanford, 

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

 it can also be easily distinguished by the characteristic, crowded, 

 well-developed, nearly perpendicular, longitudinal striation, vary- 

 ing slightly in direction on each whorl, much as in many species 

 of Pomatias. The columella also is peculiar." (Nevill.) 



When first publishing the name Glessula blanfordiana, Nevill 

 only added very few words of description and gave no dimen- 

 sions. This referred to the type from Ponsee, in Yunnan, 

 collected by Anderson. Althougli he does not expressly state 

 this, it may be presumed that the Bhamo specimens were also 

 collected by Anderson. He subsequently, in 1881, gave a full 

 description which has here been copied. Although the type is 

 stated by Nevill to be in the Indian Museum, the species is not 

 included in his ' Hand List of Mollusca in the Indian Museum.'
