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

 pi. 15, figs. 5,5a,5b (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, suture 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. 



Hob. Burrail Eange, Naga Hills. 



Distinguished by minute perforation from the umbilicate 

 K. kezamahensis and lailangkotensis, also by sculpture and other 

 characters. 



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

 fig. 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 lielicifera ; aperture subvertical, angularly 

 lunate ; peristome thin, columellar margin very oblique.

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

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



Original description: Shell globosely conoid, keeled, imper- 

 f orate, 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. 1-6, height 1*1 mm. 



Hob. Dikrang Valley, Dana Hills (Godwin- Austen). 



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

 form and comes nearest to K. ? nongsteinensis (Jainta Hills), but
