A rather short thick species, with a very blunt ape.K, 

 differing from all others of its size in the entire lack of any 

 attempt at perforation. The fact that the smallest specimi-n 

 measured above contains eggs supports the idea that the 

 larger ones are at least almost mature. 



14. Euonyma varia, sp. n. (PI. VI. figs. 5, G, 7.) 



Shell elongate, narrow, turriform, rimate, pale yellowish 

 olivaceous, thin, moderately glossy and transparent. Si)ire 

 produced, acute, apex narrowly rounded. Wiiorls 10^, 

 slightly convex, more so just below the suture; gradually 

 and regularly increasing; the first two smooth, remainder 

 covered with numberless very fine, faint, regular, curved, 

 close-set striw, imparting a slight silky gloss to the shell. 

 Suture somewhat impressed. Aperture ovate, bluntly rounded 

 at base. Peristome thin, simple. Outer lip a little swollen 

 and then incurved, rather sharply arched forward to about 

 1^ mm. l)elow the suture, and then noticeably receding in an 

 almost straight line to the base. Columella nearly straight, 

 margin narrowly triangularly reflexcd. Callus none.

A widely distributed species, to be found in many museum 

 and private collections. Extreme forms differ very con- 

 siderably in contour. The type, from Pienaais Poort, is 

 about intermediate, with an eveidy tapering spire and mode- 

 rate apex. In a more slender form from Zwart Kop the 

 apical whorls are finor and narrower, giving a more tapering 

 and often slightly crook-'d appearance to the spire ; in a 

 coarser form the apex is blunter and the spire approaches 

 K. turriforinis in contour. The gloss and transparency is
