In the type specimen of this species (pi. 24, fig. 14, copied 



from Kuester) the last whorl ascended a little farther than in 



that drawn in pi. 24, figs. 15-17, from the Nerbudda valley 



(Indian Museum). The latter is also smaller, alt. 2.65, diam. 



3.2 mm. 



The shell is perforate, very compactly coiled, regular in 

 shape as far as the last half-whorl, where the whorl becomes 

 straightened and ascends. The peristome is slightly thickened 

 within and a little expanded. The nearly straight parietal 

 margin stands free of the penult whorl, and barely detached 

 from the last whorl. The plane of the peristome stands at an 

 angle of about 40 with the axis of the shell. The surface is 

 smooth, some very faint growth-lines being visible under the 

 lens. There is also a microscopic granulation, such as most 

 Pupge show under sufficient magnification. The apex appears 

 to have only an extremely minute and indistinct granulation.
