512 Ml-. M. Connolly on 



Long. GO, lat. 1-9; apert., alt. 1'6, lat. 08 ; last wliorl 

 2*7 mm. 



Hab. Uganda, Mt. Elgon (JVoodhouse). 



Streptostele {Rajff'raya) aiiriformis, sp. n. 

 (PI. XIV. fig. 7.) 



Shell very small, shortly acicular, rimate, rather thin, 

 smooth, translucent, milky-oli^'aceous. Spire produced, 

 sides nearly parallel from base to 5th whorl, and then 

 tapering slightly more rapidly to the narrowly rounded apex. 

 Whorls 7, convex, gradually increasing, the first 3 practically 

 smooth, remainder sculptured with very faint, close, straight, 

 vertical striae; suture subcrenulate, well defined. Aperture 

 quadrate, broadly rounded at base; peristome white, shining, 

 thickened and extremely narrowly reflexed ; outer lip 

 moderately outcurved, slightly sinuous at the angle at which, 

 after advancing very gradually a short distance in profile, it 

 recedes rather rapidly to the base; columella slightly oblique, 

 with a vertical groove towards its upper extremity, margin 

 narrowly reflexed, almost concealing the small rima; there 

 is a slight tendency towards a callus, but no dentition. 



Long. 4*7, lat. 16; apert., alt. 1'2, lat. 0"G; last whorl 

 2-2 mm. 



Hab. Kenya, Riimruti, Laikipia Plateau, 7000 ft. {Kemp). 



Streptostele [Rafrayd) cijl'mdrica, sp. n. 

 (PI. XIV. fig. -iL) 



Shell very small, acicular, rimate, thin, smooth, shining, 

 transparent, very pale olivaceous-vitreous. Spire produced, 

 sides slightly convex at the 4th whorl, apex rounded. 

 Whorls G|, almost flat, very gradually increasing, the first 

 2 smooth, remainder, under a strong lens, practically so, the 

 sculpture only being noticeable in the impressed, strongly 

 creuulate suture. Aperture piriform, peristome white, 

 shining, a little thickened and minutely reflexed ; outer lip 

 hardly curved outward, angulate very slightly forward and 

 then receding more rapidly to the base ; columella rather 

 concave, margin narrowly reflexed over the rima ; callus and 

 dentition none. 



Long. 4*1, lat. 1"3 ; apert., alt. 1"1, lat. 0*7; last whorl
