Locality. Nag-Tiba ridge near Mussoorie, N.W. Himalaya. 
Shell very depressedly conoid, thin, polished, flat on base, concave 
round umbilicus; sculpture longitudinal, linear, wide apart, not 
very regular, ribbon-like, minute transverse lines of growth (Plate 
XXI. fig. 3); colour dark horny brown, pale ochre near aperture ; 
spire flatly convex, apex rounded; suture shallow, adpressed ; 
whorls 8, closely wound, sides above flat, round on the last : aper- 
ture narrowly lunate, oblique; peristome thin, straight, slightly 
sinuate below, scarcely reflected at umbilicus and descending very 
obliquely ; umbilicus almost hidden. 
Size: maj. diam. 15-5, min. 140; alt. axis 6°8, body-whorl 5:0 inch.

Some specimens are considerably larger than this. Abundant under 
stones and fallen trees at 7000-8000 it. 
Animal. Very pale grey ; tentacles grey, extremity of foot glan- 
dular. 
Original description :—“ Testa discoidea, purpureo-brunnea, politi, 
leviter concentrice et radiatim striata, striis radiates remotis, illis con- 
fertissime dispositis ; spira vie elevata, anfractibus sepiem (apice 
omissa) arcte convolutis ; apertura lunata, labro striga, tncrassata 
interna distante munitum. 
«¢ Diam. 0-65 (B.). 
‘© Animal as in the genus; the colour a dark verdigris-green. 
“This beautiful species is found in great abundance in the forest 
of Mahdssé, beneath fallen timber, and in the hollow trunks of 
decaying trees; it is also plentiful at Fagu and Nagkunda at 
9000 ft., and has been met with at Hattu at 10,656 ft. All these 
places have a greater elevation than Simla, where it has not yet 
been discovered” (H.). 
‘The closely packed whorls, showing a larger number in asmaller 
diameter, at once distinguished this species from all the darker- 
coloured and more depressed varices of NV. vitrinoides i Ba): 
I have just obtained spirit-specimens from Mr. Theobald, collected 
by him at Murree, and the shell now finds a generic resting-place. 
The animal has a very small right shell-lobe and a small left shell- 
lobe, the left dorsal lobe being very distinctly divided into two 
separate lobes. This will be described in more detail. Regarding 
the genus Bensonia referred to, Pfeiffer evidently regarded labiata
