270 Major M. Connolly on 



Hab. Cape Colony, Mountain Drive, Grahamstown 

 (Farquhar). 



A comparatively slender form, the spire being more pro- 

 duced, with straighter sides, than in most of the foregoing. 



9. Curvella majubana, sp. n. (PI. VI. fig. 13.) 



Shell conic-ovate, narrowly umbilicate, thin, glossy, trans- 

 parent, pale olivaceous. Spire produced, evenly tapering, 

 apex rather acute. Whorls 6, regularly and somewhat 

 rapidly increasing, slightly convex, the first two smooth, 

 remainder beautifully sculptured with very fine, clear, close 

 stria?, following the curve of the outer lip. Suture simple, of 

 moderate depth. Aperture ovate, rounded at the base. 

 Peristome simple, acute. Outer lip slightly curved outward 

 and about equally arcuate forward. Columella straight, 

 margin narrowly triangularly reflexed over (nearly concealing) 

 the umbilicus. 



Shell 9"6 x 3*4, aperture 3'5 x 1*6, last whorl 5*3 mm. 



Hab. Natal, Amajuba, in an ants' nest {Connolly). 



A pretty shell, the most graceful of yet known South- 

 African Curvella?, and easily distinguished by the symmetry 

 of its form and acuteness of its apex. Its nearest ally is the 

 East-African C. associata, E. A. Smith, from which it differs 

 chiefly in its finer apex and fainter sculpture. In dead 

 specimens the shell is often clouded with yellowish white. 

 Adult shells usually show trace of a white callus. 



10. Curvella saundersce, sp. n. (PL VI. fig. 14.) 



Shell conic-ovate, rimate, olivaceous, thin, glossy, trans- 

 parent. Spire produced, evenly tapering ; apex rounded. 

 Whorls 5^, rather rapidly increasing, slightly convex, the 

 first two smooth, remainder extremely faintly marked with 

 close curved striae, barely visible to the naked eye. Suture 

 rather shallow. Aperture ovate, bluntly rounded at base. 

 Peristome simple, acute. Outer lip slightly curved outward 

 and arcuate forward. Columella straight, margin narrowly 

 triangularly reflexed. Callus none. Shell 7*6 x 3*4, aperture 

 3'2x 1*5, last whorl 4 - 9 mm. 



Hab. ZuLULAND, Eshowe {Lady Saunders). 



A nearly smooth graceful species, whose nearest alliance is 

 with C. majubana } from which it is separated by its blunter 

 apex and fainter striation.
