MOLLUSCA OF INDIA. 89 
apice obtuso ; anfractibus 53 arcte convolutis, convexiusculis, ultimo 
ad peripheriam rotundato, subtus convexo ; apertura vie obliqua, late 
lunari, peristomate recto, acuto, margine columellart anguste reflexo. 
«« Diam. major vix 5, minor 4, axis 3 mill. 
“‘ Habitat ad Rangoon, satis copiose. 
“A minute shell, with a more conoid spire and more closely 
wound whorls than H. causia. It is altogether deficient in the 
spiral strie which distinguish that species.” 
Fine, longitudinally striate sculpture ; globosely conoid. 
MAcROcHLAMYS UMBRATICOLA, 0D. sp. (Plate XIV. figs. 4, 4a.) 
Locality. Hengdan Peak, North Cachar Hills (H. H. G-A.). 
Shell, perforation concealed, globosely conoid; sculpture very 
minute, regular, longitudinal striz ; colour pale olive-brown ; spire 
low; whorls 43; aperture ovately lunate, suboblique ; peristome 
rather thickened, very slightly reflected. 
Size: major diam. 0°17 inch, alt. axis 0°08 inch. 
é 4-3 mm., af 2-2 mm. 
This shell was very abundant among the dead leaves in the forest 
around the above-mentioned peak; I also got single specimens in 
the Jatinga valley and Kopamedza Peak, 8376 ft., in the Naga Hills.

Nanina (Microcystis), Nevill’s Hand-list, p. 37. no. 156. 
Locality. Moulmain (Stoliczka). 
Shell perforate, rounded below, glassy ; sculpture, regular longi- 
tudinal fine ribbing throughout, crossed by evenly disposed lines of 
growth, but not decussate ; colour umber-brown ; spire conoid, apex 
rounded; whorls 4, much rounded ; aperture lunate. 
Size : major diam. 0-09 inch, alt. axis 0°05 inch. 
Fe 2:3 mm., Pe 1-3 mm. 
Original description :—“ Testa perforata, depresso-globosa, oblique 
striatula, sub epidermide cornea albida ; spira conoideo-convexa, apice 
obtuso, sutura impressa ; anfractibus 43 sensim crescentibus, convext- 
usculis, ultimo rotundato, subtus convexo ; apertura obliqua, rotun- 
dato-lunari, peristomate recto, acuto, margine columellari reflexo, sub- 
oblique descendente, basalt arcuato. 
“Diam. major 2, minor 13, axis 11 mill. 
**‘ Habitat ad Phie Than, raro. 
“ Allied to H. molecula, but, besides its much smaller size, it is 
more globose. The single specimen received is much weathered. 
It is probably translucent and polished when fresh. The spire is 
less conoid, and the whorls not so closely wound as in H. bullula, 
Hutton, of the Western Himalaya.” . 
Nevill gives (J. ¢. p. 37) Parisnath and Darjiling as localities 
where this shell has been found. These specimens should be again 
closely compared with typical examples.
