the South- African Stenogyrinse. 255 



Not a Subulina, I place it provisionally in Euonyma on 

 account of its kinship to linearis, from which it is apparently 

 separable by its shorter aperture. 



Euonyma pietersburqensis (Preston), var. lev is (nov.). 

 (PI. VI. fig. 8.) 



Shell elongate, narrow, turriform, sublimate, thin, glossy, 

 transparent, pale olivaceous. Spire produced, acute, slowly 

 and evenly tapering ; apex rounded. Whorls 9^, gradually 

 increasing; slightly convex ; the first two smooth, the very 

 fine curved striae on the remainder being scarcely visible 

 without a lens. Aperture short, almost oblong, rather flat- 

 tened at the base. Peristome simple, acute. Outer lip 

 nearly straight, very slightly arched forward and a little 

 retracted towards the base. Columella straight, margin 

 extremely narrowly reflexed, almost entirely adnate. Callus 

 none. 



Shell 12-4x3-0, aperture 3-1 X 1*3, last whorl 4'9 mm. 



Hab. Teansvaal, Warmbaths, Pienaar's Poort, Pietpot- 

 gietersrust (Connolly) ; Zoutpansberg (Cregoe). 



Smoother and more polished than typical E. pietersburg- 

 ensis, but running into it through large series. Hardly so 

 slender a form as E. crystallina, M. & P., with comparatively 

 shorter broader aperture. More glossy and less markedly 

 striate than E. linearis, Krs. 



E. pietersbicrgensis and the smoother var. levis agi*ee rather 

 nearly with both the original figure and description of 

 E. linearis ; as, however, they certainly do not agree with 

 the Stockholm cotype of the latter, they must for the present 

 be considered distinct. 



3. Euonyma crystallina (Melv. & Pons.).

 1906. Euonyma crystallina, M. & P., Pilsbry, Man. of Conch, xviii. 



p. 45, pi. x. fig. 81. 



Hab. Very widely distributed over Zululand, Natal, and 

 the Eastern Province, Cape Colony. 



A slender little shell, very near the narrow bordei--line 

 between Opeas and Euonyma. Far smoother and more highly 

 polished than E. linearis, with rather less convex whorls and 

 more regularly tapering spire.
