OiS^ SOUTH AFRICAN ENNE-E. 71 



species with E. arnoldi Stur., to which it bears a strong- 

 resemblance ; but the former is easily distinguished b}^ its 

 wider, less obstructed aperture, and the two teeth on the 

 columellar lip which are absent in Sturany's species. 



Ennea inhluzaniensis n. sj). PI. Y, figs. 53, 54, 55. 



Shell small, cylindro-elliptical, deeply rimate, thin, shining, 

 semi-transparent, apex rounded; w^horls 6^, slightly convex, 

 the first 2h smooth, the next 3.^ delicately transversely striate 

 immediately below the suture, with occasional stria? passing 

 partly or wholly across the whorl, and the last i-whorl more 

 strongly, regularly striate across its breadth, round the base, 

 and into the rimal depression ; suture moderately impressed ; 

 aperture erect, oblong, w^th Avhite peristome slightly 

 thickened and moderately expanded, the ends joined by a 

 distinct white callus, and furnished with the following pro- 

 cesses : A rather narrow, sharp, in-running parietal plait 

 arising a little above the suture and in front of the plane of 

 the peristome, a rather long, narrow, simple, sub-central 

 labral tooth, and a small, rounded, internal columellar plait. 

 There is also a slight, svib-central swelling on the columellar lij). 



Height 3'60, width 1*47 mm. 



Hab. — Inhluzani Hill, Dargle, Natal (Burnup). 



Among the forty-five specimens collected, scarcely any 

 deviation from the type, except in size, is observable. The 

 " columellar plait " of the description is merely the rounded 

 termination of the axial column Avithout contortion or 

 thickening. The labral tooth is more solid than is usual, the 

 excavation behind the lip being very shallow ; but the 

 position of the tooth is there very clearly shown by a con- 

 spicuous white spot. The swelling on the columellar lip is 

 scarcely thickened, the corresponding excavation being very 

 deep. 



In the study of this shell I feared, from Melvill and 

 Ponsonby's description and figure of Ennea juxtidens, 

 and from two very poor specimens, immature, calcined, and
