sculpture is almost obliterated by the beginning of the for- 

 mation of a callus. A second example of this shell, found at 

 Table Mountain (Natal), at a distance of about 50 miles 

 from Umbogintwini, and at an altitude of fully 2,000 feet 

 above the sea (while the last named locality is little above 

 sea-level), has the callus, which is almost pure white, in a 

 more advanced state of development, and the labrum more 

 triangularly reflexed, and is 23 mm. long by 7 mm. broad. 

 It also has the thin labrum slightly damaged (Burnup}.

Shell acutely turrited, slender, pellucid, whitish-corneous,

 nearly equal, gradually gradate towards the apex; apex 

 somewhat papillar. Aperture ovate ; peristome simple, acute.

"A remarkably delicate, shining, pellucid shell, differing 

 from all the species of the genus hitherto described, though 

 its characters are simple enough 7 ' (M. & P.). 



Two specimens are before me, the larger being figured, pi. 

 10, figs. 73, 74. The shell tapers 'almost straightly, but is 

 just perceptibly contracted near the obtuse, rounded sum- 

 mit. It is very glossy, pale greenish-yellow, corneous, and 

 shows only very weak wrinkles of growth. The upper whorl 

 is smooth, hemispherical; the third whorl is 2 mm. in diam. 

 The whorls increase very slowly, and the last is short. Aper- 

 ture oblique, ovate, the columella concave, its edge reflexed 

 and adnate. Length 32.7, diam. 7.8, length of aperture 6.5 

 mm. ; whorls 12.

 Shell fusiform, tapering above, thin, a little shining, rather 



smooth, pale olive- greenish. Whorls 9, the first two mamil-
