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

 very obtuse apex and excavated suture ; wliorls six, scarcely 

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

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

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

"This species closely resembles Glessula peguensis, 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 striatiou, vary- 

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

 oiPomatias. The columella also is peculiar."' {Nevill.) 



When first publishing the name Glessula hlanfoi'diana, IXevill 

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

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

 collected by Anderson. Although 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 Lidian Museum.'
