MOLLUSCA OF INDIA. INF 
in form; and I possess three specimens from Upper Burmah out of 
the Indian collection. Nevill says, ‘‘ This species was found abun- 
dantly at Bhamo and in the second defile of the Irawady. The spe- 
cimens are quite undistinguishable from others in the Museum from 
Mergui (typical locality). [ think it doubtful if Godwin-Austen’s 
NV. atricolor from the Shisha valley will prove really distinct.” The 
closely wound whorls, their greater number, and the flattened form 
of M. resplendens are very distinct characters, and these two forms 
cannot be confused. ‘ Shisha valley ” (/. ¢.) is an error of copying or 
printing; there is no such place.

More globose and tumid than the typical specimens from Munipur 
and the Naga Hills. 
MAcROCHLAMYS ATRICOLOR. 
Locality. Toruputu Peak, Dafla Hills. (Plate XXIV. fig. 4.) 
Shell, umbilicus very narrow, almost concealed, subglobosely 
conoid ; sculpture smooth, glassy surface, with indistinct longitudinal 
lines on last whorl, not apparent on the apical portion ; colour pale 
olivaceous brown ; spire moderately high, apex blunt; suture well 
defined ; whorls 5, convex, the last well rounded and rather ven- 
tricose ; aperture moderately thin, subvertical; peristome broadly 
lunate, horizontal at base, slightly sinuate and oblique near 
columellar, 
Size: maj. diam. 19-0, min. 16°8 ; alt. axis 8-4, body-whorl 6-4 mm. 
Very similar to specimens from Munipur. 
MacrocH1LaMyYs CAcHARICA, n. sp. (Plate XXVII. fig. 2. 
Locality. Munipur Hills. 
Shell subperforate, very depressedly conoid and flat on the base, 
thin, glassy ; sculpture none save transverse strive of growth; colour 
pale sienna-brown ; spire flatly conoid, apex subacute; suture 
moderately impressed; whorls 5, regularly increasing; aperture 
subvertical; peristome thin, sinuate below; columellar margin 
weak, oblique, non-reflected.

This shell may be distinguished from JV, atricolor of same size by 
its flatter base and less rounded apex. 
The animal is, as regards its outward form, exactly as in MW. atri- 
color ; but the generative organs (Plate XX VII. fig. 2c) are modified. 
The male organ is like that of M. indica with a longer kalc-sac, and 
the spermatheca is short and club-shaped with a rounded terminal 
portion. There is, however, no amatorial organ, and I have exa- 
mined four specimens. Another instance of its absence in certain 
species is exemplified in Durgella, a point that has been noticed 
by Stoliczka. The jaw (Plate XXVII. fig. 2a) is slightly convex 
on the upper margin, still more so on the cutting-edge, with a large
