4*8 HELICID^l. 



This species is the type of PfeifFer's sub-genus Oxytes. From 

 a drawing of Dr. Stoliczka's, the animal resembles JV. ligu- 

 lata and N. JiaugJitoni as to the furrowed body and distinct 

 pedal row. It differs, however (resembling that of N. orobia), by 

 the larger, more excavated gland, pointedly oval-shaped, and 

 extending to the sole of .-the foot.
