MOLLUSCA FROM EQUATORIAL AFRICA. 197' 



Ennea kivuexsis, sp, n. (PI. XXXIV. fig. 3.) 



Shell differing from E. rtiargarita in its smaller size, rather 

 more cylindrical form, and generally thinner texture ; the trans- 

 verse sculpture is more marked, the penultimate whorl is pro- 

 portionately less gibbous, and the last whorl is comparatively 

 broader than is the case in that species. 



Alt. 10"5, diam. maj. 6*25 mm. 



Aperture : alt. 4*25, diam. 3 mm. 



Hah. Near Lake Kivu, Belgian Congo i^Rohin Kemp). 



Ennea innocens, sp. n. (PL XXXIII. fig. 11.) 



Shell scarcely rimate, rather large, cylindrically ovate, cream- 

 coloured, smooth, shining ; whorls 6, rather flat, the first three 

 regularly, the remainder rapidly, increasing in size, the last very 

 slightly ascending in front ; suture impressed ; columella vertically 

 descending, slightly bulging in the middle, nai-rowly outwardly 

 expanded ; labrum white, very narrowly reflexed and dilated 

 below ; aperture irregularly subquadrate, edentulate.

Aperture : alt. 5'25, diam. 3"25 mm.

 6000 feet {Rohin Kemp). 



Ennea elgonensis, sp. n. (PI. XXXIII. fig. 3.) 



Shell allied to E. innocens, but much smaller and with more 

 obtuse apex, though having the same number of whorls ; the 

 umbilical depression is proportionately broader, the columella 

 descends in a curve, the labrum is not dilated below, and the 

 aperture is ovate instead of being subquadrate as in E. innoce^is.

Aperture : alt. 4, diam. 2*75 mm.

. Ennea ingloria, sp. n. (PI. XXXIII. fig. 10.) 



Shell small, shortly cylindrical, thin, whitish ; whorls 6, 

 the first four regularly increasing, the fifth and sixth rather 

 rapidly increasing in length, but not in breadth, smooth but for 

 coarse growth -markings, the last two whorls convex ; suture 

 impressed, strongly crenellate below ; perforation very narrow ; 

 columella slightly oblique and outwardly expanded ; labrum nar- 

 rowly dilated below and reflexed ; aperture edentulate, subovate.
