MOLLFSCA OF INDIA. 175 



shown on the basal side ; colour very pale ochre ; spire moderately 

 high, sides flat ; suture shallow. Whorls 5, sides flatly convex ; 

 aperture not complete, probably quadrate ; peristome thin ; colu- 

 mella broken. 



Size : maj. diam. 3-8, alt. axis 2 mm. 



The form of this shell is very like that of K. nagaensis, figured 

 on Plate II. fig. 11 of this work. I give a drawing of the sculpture 

 of the type shell from the Anghami Naga Hills, which shows how 

 very different it is in this character (Plate CUT. fig. 10). 



Kaliella richilaensis, n. sp. (Plate CIII. figs. 2, 2b.) 



Localitif. Eichila Peak, Bhutan frontier, 10,370 feet {W. Robert). 



Shell globosely conoid, very rounded below, very narrowly umbili- 

 cated : sculpture, transverse distant costulation, rather fine, not 

 regular (fig. 2 b) ; colour pale sienna-brown ; spire moderately high, 

 sides flat ; apex blunt ; suture impressed ; whorls 5, keeled on the 

 last, but with no cariuation, flatly convex ; aperture narrowly 

 lunate ; peristome thin ; columellar margin nearly perpendicular, 

 reflected near the umbilicus. 



Size : maj. diam, 3-3, alt. axis 1-8 mm. 



Somewhat of the form of K. nagaensis : it is, however, a smaller 

 shell and the sculpture is not so fine and regular as in that species. 



Kaliella richilaensis, n. sp., var. (Plato CIII. fig. 2 a.) 



Locality. Richila Peak, Bhutan frontier, 10,370 feet. 



Shell globosely conoid, not umbilioated, covered with a strong 

 epidermis ; sculpture very regular fine costulation ; colour strong 

 sienna tint ; spire moderately high, conoid, apex rounded ; suture 

 shallow ; whorls 5, rather flatly convex ; aperture narrowly lunate ; 

 peristome thin ; columellar margin subvertical, but very slightly 

 reflected. 



Size : maj. diam. 3-6, alt. axis 2*2 mm. 



Kaliella sikkimensis, (Plate CIII. fig. 4.) 



Kaliella sikhimensis, Nevill MS., Land & Freshw. Moll. Ind. pt. ii. 

 p. 22, pi. V. fig. 9. 



Locality. Shell now figured is from the Eisett chu Valley, South 

 Sikkim ( W. Robert). 



Shell globosely conoid, scarcely perforate : sculpture very fine, 

 close, regular, transverse striation ; colour pale sienna-brown ; spire 

 conical, less than the major diameter, apex blunt, sides convex ; 

 suture moderately impressed ; whorls 6, rather convex, closely 

 wound ; aperture narrowly lunate, vertical ; peristome thin, colu- 

 mellar margin oblique and but slightly reflected. 



Size : maj. diam. 1-9, alt. axis 1-fi mm. 



This pretty little shell, of which the type described by me is in
