For want of a better, I have named this shell after the Demon 
Tirut, to whom the Khasias so constantly sacrifice and propitiate 
with offerings.

slightly and finely hairy when fresh; colour pale horny brown;

A single specimen only obtained by Mr. A. Chennell, of the Topo- 
graphical Department, who brought in a number of shells when 
surveying the above hills, for which I am deeply indebted to him 
and other members of the Topographical Survey who assisted in 
surveying the Assam hill-country. 
Herrx ? (——?) etomerosa, n.sp. (Plate XIV. fig. 9.) 
Locality. Dikrang valley, Dafla Hills (H. H. G.-A.). 
Shell globular, subperforate ; sculpture indistinct, very close longi- 
tudinal striz; colour dull olivaceous ; spire conoid, rounded above, 
sides convex; suture shallow ; whorls 6, the last very tumid; aper- 
ture narrowly lunate, contracted slightly on the outer margin, a 
well-marked callus on the body-whorl; peristome strong for size 
and somewhat thickened below into an indistinct tooth, columellar 
margin oblique. 
Size: major diam. 1:3 mm., alt. axis 0°-7 mm. 
x 0-05 inch, ,, 0:03 inch. 
This very minute pretty shaped shell is unlike any thing I have 
found in India; and I place it in the Helicidie, for its true relation- 
ship is very uncertain.
