431. Kaliella ? burrailensis, Godioin-Austen, Mol. Ind. i, 1883, p. 70, 

 pi. 15, figs. 5, 5 a, 5 b (shell). 



Shell minutely perforate, lenticular, thin, transversely obliquely 

 ribbed and decussated by rather irregular striation above, below 

 radiately and more strongly but very irregularly concentrically 

 ribbed, pale horny ; spire low, conoidal, sides convex, sutui-e very 

 shallow, apex slightly prominent ; whorls 5|, flat above, the last 

 keeled, convex beneath, not so prominent as the spire ; aperture 

 subvertical, angulately lunate, narrow ; peristome thin, columellar 

 margin oblique. 



Diam. 5, whole height 2*6 mm. 



Hab. Burrail Eange, Naga Hills. 



Distinguished by minute perforation from the umbilicate 

 K. Icezamahensis and lailangkotensis, also by sculpture and other 

 characters. 



432. Kaliella ? ruga, Godvnn-Austen, Mol. Ind. i, 1883, p. 70, pi. 15, 

 tig. 4 (shell). 



Shell perforate, sublenticular, transversely ribbed and decussated 

 by impressed lines above and below, pale horny ; spire low, 

 conoid, suture impressed ; whorls 5, convex, the last sharply 

 angulate, tumid below, more swollen than the spire is above the 

 keel ; a small pitted mark behind the lower margin of peristome, 

 showing inside the aperture as a minute plait, not always con- 

 spicuous, as in Sesara helicifera ; aperture subvertical, angularly 

 lunate ; peristome thin, columellar margin very oblique.

[433. Kaliella? dikrangensis, Godwin-Austen, Mol. Lid. i, 1883, 

 p. 72, pi. 16, fig. 3 (shell). 



Original description: — Shell globosely conoid, keeled, imper- 

 forate, much rounded below ; sculpture very microscopic, transverse 

 regular costulation, the finest I have seen ; colour pale amber ; 

 spire pyramidal, sides nearly flat, apex well rounded, suture 

 moderately impressed ; whorls 6, closely wound ; aperture nar- 

 rowly quadrate ; columellar margin strong, perpendicular, with a 

 slight protuberance on the inner margin. 



Major diam. 1-G, height 1-1 mm. 



Hah. Dikrang Valley, Dafla Hills {Godwin- Austen). 



This shell, of which I only possess one example, is similar in
