African Non-marine MoUusca, 1^59 



Hab. S. Rhodesia, Kliami (Tnrton) ; Bulawayo (in S. 

 African Museum) ; Lusanyama District (Quekett). 



Larger than any species liitlierto described from South 

 Africa, and not very closely resembliiif^ any known to me 

 from further north, being a rather smaller form, with com- 

 paratively longer whorls, than S. odona, Brug., and. its 

 allies. I have much pleasure in naming this South i\frican 

 land-shell after its discoverer, Colonel W. 11. Turton, as a 

 tribute to tlie great work accomplished by him in regard to 

 the mnrine fauna of the subcontinent. 



Suhulina viridula, sp. n. (PL I. fig. 25.) 



Shell of fair size, elongate-turriform, imperforate, thin, 

 rather silky, transparent, dark olivaceous. Spire produced, 

 slightly attenuate from the 6th whorl, apex narrowly 

 rounded. Whorls 10, almost flat, regularly increasing, the 

 first 2 smooth, remainder sculptured with well-defined, close, 

 regular, nearly straight, vertical, transverse strise, very faint 

 on the 3rd whorl and gradually increasing in strength ; 

 suture but little oblique, crenulate from the base of the 

 3rd whorl onward. Aperture subovate, peristome simple, 

 acute ; outer lip straight and almost vertical in profile ; 

 columella concave, sharply and abruptly truncate at base. 



Long. 18-0, lat. 4*2 ; apert., alt. 4*1, lat. 2*0 ; last whorl 

 67 mm. 



Hab. Uganda, Kigezi,6000ft.; Belgian Congo, Mukanda, 

 near Lake Kivu {Kemp). 



A pretty species of rather unusual colour, clearly differing 

 in apical sculpture from S. ylyptoceyhala, Pilsbry. 



Subulina entebbana^ Pollonera, 1907. 



1907. Suhulina octona, Cbem., var. entehbana^ PoUon, Boll. Mus. Torino, 



No. 5G8, p. 2. 

 1913. Subulina victories, Ivob. Rev. Suisse Zool. xxi. p. 73. 



Examples of this species were collected by Kemp at 

 Jinja, Entebbe and Kampala, and distributed by Preston 

 under the name of the first-mentioned locality. They appear 

 to agree in every respect with S. victorice, Kobelt, described 

 Irom the Busoga District, in which Jinja is situated, and 

 with S. octona entebbana, PoUon., and establish synonymy 

 between them. Pollonera^s name has precedence, and 

 appears worthy of specific rank ; the shell is far more 

 strongly sculptured than that of S, odona.
