" Tliere was one solitary specimen in my collection of this 

 species from north of the Burrail, and 6 specimens, but smaller 

 in size (4'5 millim. in height of spire), from the peak of IShiroit'ui'ar, 

 in the Lahupa-Xaga Hills, north of Munipur. Mr. Aldridge's 

 collection contains a large number, and 1 have selected the type 

 out of these. 



" On the boss of trap rock near the village of Phunggam 

 I found a number of a small variety, 4*5 millim. in height of spire, 

 but differing in no respect, except in size, from the typical species, 

 only that they are all of a pale sea-green tint. 



" The same form occurred on Kopamedza Peak, with this 

 difference, that the constriction wiis more to the right, directly 

 over the outer margin of the peristome. Prom Prowi, specimens 

 were still smaller in size, 3"S millim." {^Godwin- Austen.)
