worn in the type, remainder painted with numerous narrow, 

 nearly vertical, rufous streaks, for the most part straight, 

 but occasionally irregular. Spire produced, side^ nearly 

 regular, apex acutely conic. Whorls 10, but little convex, 

 gradually and regularly increasing, the first 2 much worn 

 and malleate, the 3rd closely microscopically spirally striate, 

 4th similar to 3rd, but with faint transverse striae, w^hich 

 continue more strongly on the remaining whorls, on all of 

 which are occasional, irregularly spaced, rather distant, 

 deep, spiral grooves ; suture shallow. Aperture subovate, 

 peristome simple, acute; outer lip but little outcurved, 

 nearly vertical in profile ; columella rather long, very 

 slightly convex, narrowly obliquely truncate at base ; callus 

 not thick, but continuous up the columella and across the 

 paries. 



Long. 33-8, lat. 12'0 ; apert., alt. 97, lat.^5*4j last whorl 

 15*5 mm. 



Hab. Kenya, Kekumega ( Percival) , 



Perhaps nearest to H. elliotti (Smith) *, from which it 

 appears to differ in being a slightly more slender form, with 

 finer apex and rather shorter whorls.

The type of this species is, unfortunately, in such in- 

 different condition that, until topotypes come to hand, it is 

 inadvisable to attempt to differentiate from it a variety of 

 races which hail from many parts of Kenya Colony and 

 may, in some cases, represent distinct species. The extreme 

 form from Kekumega, illustrated by fig. 21, is obviously far 

 more obese than the type, but differs little from it in sculp- 

 ture and length of whorl, and, as intermediates occur, I 

 prefer to regard them all, for the present, as one species. 



Nothapalus ugandanus, sp. n. (PI. I. fig. 26.) 



Shell small, subfusiform, imperforate, thin, smooth, shin- 

 ing, transparent, normally pale olivaceous. Spire produced, 

 sides rather convex, apex narrowly rounded. Whorls 6, not 

 very convex, rather rapidly increasing, the first 2 practically 

 smooth, remainder engraved with rather close, but irregular, 

 shallow transverse grooves, usually bent backward just below
