All the shells enumerated under No. 43, Nanina {Macrochlamys)

Locality. Lhota Naga Hills (W. Chennell). 



Shell subglobosely turbinate, glassj ; sculpture very smooth, 

 with a few longitudinal and very indistiuct microstrise, practically 

 none, only to be seen with high power and strong light ; colour

The generative organs were got out in a very perfect state and 

 mounted. The male organ is small in comparison to the other 

 organs, has the coiled csecum to which the retractor muscle is 

 attached, but with a very small kale-sac, in fact it hardlv seems iu 

 the full matured form. The'spermatheca on the other hand was 

 large and long and contained a perfect spermatophore, the flume 

 of which had long bitid spines (tig. \a) on one side, also near the 

 base of the capsule (fig. Ic), the last being much larger and stronger. 

 The head of the capsule (fig. Ih) is blunt, terminating iu a long 

 tube, the part formed within the vas deferens of the animal with 

 which this one wsisincoitu. The amatorial organ is long and large.
