"Full grown shells collected in the Teesta Valley near 

 Darjiling, and in N. Canara, measure 44 mm. in length, and 

 have 14 whorls" (Beddome). G. baculina and G. pertenuis 

 are considered to be specifically inseparable from G. tenui- 

 spira by Col. Beddome, a conclusion supported by the speci- 

 mens before me. The presence of this trans-Gangetic snail 

 in the North Canara Hills is remarkable, if indeed, the Canara 

 shells are really of the same species.

 brown or corneous-fulvous, covered with a glossy cuticle. 

 Spire turrite, the apex rather obtuse. Whorls 13V2> slightly
