forest. Dead shells may be sometimes seen in hundreds in the clearings 

 after the cut jungle has been fired, when all the surface vegetable mould 

 is burnt and the ground deeply heated ; in this way many local forms of 

 landshells are destroyed off large areas as the country becomes cleared, and 

 many of the more local species no doubt have thus died out. 



Altc^tjs inflatus, n. sp., Plate III, Fig. 1. 



Shell depressedly turbinate, solid, pale ochreous horny, moderately umbi- 

 licated, smooth, finely sculptured on the swollen portion of the last whorl 

 adjacent to the sutural tube. Spire conoid, apex blunt ; suture impressed. 

 "Whorls 4|^, the last very much swollen for the size of the shell. Constriction 

 smooth, very short. Sutural tube moderate. Aperture oblique, circular ; 

 peristome double, solid, united, and reflected. Operculum concave, black, 

 its position far forward at the very ed^gQ of the aperture.

Hohitat. — I first noticed this shell in the collection of Mr. F. Stoliczka, 

 who kindly allowed me to take it for figuring ; it had been found in Assam, 

 but its exact locality was unknown. In the winter of 1872-73 I was fortu- 

 nate to find it myself in the Naga Hills under Japvo Peak and again at 

 Yemi, Phunggum, and Gaziphimi at the head of the Lanier River on the 

 main water- shed. 



This shell in many respects assimilates to A. conicus, mihi, but is more 

 openly umbilicated ; in another direction it has the character of the sub-genus 

 Dioryx viz. in form of mouth, the short constriction, and position of oper- 

 culum close to the edge of the aperture. 



ALTCJ3US STEiGATTJS, n. sp., Plate III, Fig. 2. 



Shell pale corneous or amber, finely and evenly costuiated throughout. 

 Spire depressed, apex blunt and darker coloured. Suture moderate. Whorls 

 3|^, the last very little swollen, slightly constricted, with a single low ridge 

 close behind the aperture, the constriction smooth and very finely striated. 

 Sutural tube very short. Aperture slightly oblique, circular ; peristome 

 single, simple, continuous, moderately thickened. Operculum ?

This is another species of the short-sutural-tubed section of AhjccBUS^ 

 of which A. Khasiacus (vide PI. Ill, Fig. 4, J. A. S. Bengal, Vol. XL, 

 Pt. II, 1871) is a good type. The general and distinct costulation from 

 constriction to apex, particularly the form of constriction and mouth, mark 

 it as a good species. It is more openly umbilicated than A. Khasiacus,
