504 ^Ii"- ^I- Connolly on 



Hab. Kenya, Mt. Kenya, 6000-8000 feet {Kemp). 

 Distinguishable from any of its nearest allies by its flatter 

 wliorls and Hner, fainter, regular sculpture. 



Streptostele oributes, sp. n. (PI. XIV. fig. 8.) 



Shell comparatively large, elongate-tnrriform, subriraate, 

 thin, silky, nearly transparent, pale olivaceous. Spire pro- 

 duced, sides slightly convex at 7th whorl, apex acute. 

 Whorls 9i, flattish, regularly increasing, the first 2^ very 

 densely niicroscopically punctate, the next very faintly trans- 

 versely striate, remainder sculptured Avith clear, tine, close, 

 regular, slightly curved, vertical striae ; suture crenulate, 

 nearly horizontal. Aperture irregular!}^ subovate, peristome 

 slightly thickened, with trace of expansion at the rounded 

 base; outer lip hardly curved outward, scarcely advancing 

 in profile and then receding slightly to the base; columella 

 slightly concave, margin thickened so as to produce a minute 

 rima; callus and dentition none. 



Long. 12-2, lat. 3-5; apert., alt. 2-8, lat. 1-8 ; last whorl 

 4"7 mm. 



Hab. Kenya, between the Igeuibi Hills and Nyeri 

 {Kemp). 



Probably adult and, as shown by the measurements, a 

 more obese form than most of the genus. 



Streptostele elongata, sp. n. (PI. XIV. fig. 10.) 



Shell comparatively large, subrimate, much elongate- 

 fusiform, solidified and semibleached in the type, but 

 normally thin, nearly ti'ansparent, pale olivaceous. Spire 

 produced, the first 8 whorls gradually tapering, thence 

 almost parallel to the base ; apex acute. Whorls JO, rather 

 flat, very gradually increasing, the first 2 faintly micro- 

 scopically malleate, remainder sculptured with very fine and 

 close, regular, almost straight, very slightly oblique, trans- 

 verse strife, which are very faint on the 3rd, less so on 

 the 4th, and stronger on the later whorls ; suture but 

 little oljlique, simple. Aperture ovate, peristome slightly 

 tliickened, with very slight basal expansion; outer lip curved 

 outward, vertical in profile for nearly 1 mm., then receding 

 noticeably to the base; columella straight and erect, 

 triangularly thickened with slight, almost adnate, reflexion, 

 giving the ap[)earance of a minute rima : callus thick ; 

 dentition none.
