KALIELLA. 269 



Original description: — Shell globosely couoid, very narrowly 

 umbilicated, rounded below; sculphire very fine, regular trans- 

 verse ribbing; colour umber-brown; spire less than breadth, 

 apex blunt ; suture well impressed ; whorls 5.|, rather closely 

 Avound, sides convex ; aperture lunate, suboblique ; peristome 

 thin, scarcely reflected, columellar margin suboblique. 



Size : maj. diam. 2-1, alt. axis 1*4 mm. 



Compared with A'. IJwtaensis, this shell is smaller and the 

 whorls much more convex ; with typical Jtaturo, it is larger, but 

 the whorls do not increase in the same way and in the same 

 proportion ; and the same may be said of the very similar shell 

 from the Sikhim frontier, \\hich differs in having a larger body- 

 whorl and larger aperture ; they all, in fact, merge into one 

 another.]

Shell perforate, convexly conoid, subturbinate, ver}' finely 

 costulately striated under the microscope, the sculpture generally 

 obsolete, below marked with curved radiating stria^, horny brown ; 

 spire conoid, sides convex, apex obtuse, suture impressed ; whorls 5, 

 convex, last broader, rounded at periphery and below ; aperture 

 semicii'cularly ovate, subvertical; peristome thin, columellar margin 

 vertical and reflected. 



Diam. 2, height 1'5 mm. 



Hah. Manipur. 



This has a deeper suture and a broader last whorl than the 

 species of the K. nana section generally.

Locality. Richila Peak, 10,370 feet, on Darjihng-Bhutan 

 frontier ( W. Eoheri), also Eisett chu Valley and Damsang. 



Original description : — Shell globosely conoid, umbilicated ; 

 sculpture very minute, transverse ribbing, only visible under high 

 power, smooth to eye and not so regular on the last whorl as it 

 is on the rest of the whorls ; colour pale ochre ; spire, sides 

 slightly convex, apex rounded, suture well impressed ; whorls 5, 

 very convex ; aperture semilunate ; ])eristome thin, columellar 

 mai'gin suboblique and slightly reflected. 



Size : maj. diam. 2"25, alt. axis 3 '30 mm. 



It is interesting to find this minute shell in the Eastern 

 Himalaya, so extremely close in form to that I found in Munipur, 

 the sculpture on the last whorl not being so regular as in the 

 type ; it is similar above.]
