33. C. OVAMPOENSIS (Melvill & Ponsonby). PL 3, fig. 52. 



Shell small, acicular, white, very thin, the apex obtuse. 

 Whorls 4, the last produced; columella truncate at the base. 

 Aperture oblong, the lip simple. Length 3, width 1 mm. 

 (M. & P. ). 



South Africa: Ovampoland (E. L. Layard). 



Oionella ovampoensis M. & P., Ann. and Mag. Nat. Hist. 6th 

 Ser., ix, p. 91, pi. 6, f. 1 (January, 1892). A very elegant, 

 pure white, four-whorled shell, with very obtuse apex, a little 

 recalling the Cacilianella acicula (Mull.) of Europe and the 

 British Isles. (Mel. & Pons.). 



31. C. MUNZINGERI (Jickeli). PL 3, fig. 53. 



Shell imperforate, subulate, thin, glossy, hyaline, whitish, 

 longitudinally striated under the lens. Whorls 8, subinflated, 

 separated by a rather deep oblique suture, the last whorl 

 descending, one-fourth the total length. Aperture oblique, 

 vertically piriform; columella arcuate, very obliquely truncate; 

 lip acute, thin. Length 9.5, diam. 1.75, aperture 2 x 1.33 mm. 

 (Jick. ). 



Abyssinia: Beniamer, banks of the Falkat and in Habab, 

 descending from Nakfa; in the earth at roots of plants. (Jickeli).

Bourguignat has referred this species to Subulina, whether 

 correctly or not I do not know. His figures of the form taken 

 by Raffray show the sutures much less oblique than in Jickeli' s 

 figures. 



35. C. SOLEILLETI Bourguignat. PL 3, fig. 51. 



Shell lanceolate-elongate, needle-like, diaphanous, very 

 fragile, whitish, polished; spire very long, a little obtuse at the 

 summit, whorls 6, regularly and rather rapidly increasing, the
