358 AFRICAN NESOPUP/E. 



Melvill and Ponsonby's original description and figure are 

 chiefly remarkable for what was omitted. The dimensions 

 are grossly inaccurate. In their second account two species 

 appear to have been in view, though in the main it relates to 

 the true griqualandicc. 



The shell is distinctly perforate, openly rimate, long-ovate, 

 the spire with convex outlines and very obtuse apex. Color 

 cinnamon, becoming a. little darker towards the base and 

 paler towards the apex. First 1% whorls smoothish (micro- 

 scopically irregularly granulose), the rest with straight, close, 

 somewhat oblique stria?; the latter part of the last whorl 

 having a broad median furrow running to the lip, convex 

 above and below it, with a shorter impression at the base. 

 The aperture is wider in the upper part, nearly closed by 6 

 teeth : the angular lamella is subvertical, large, entering 

 deeply, curving towards and joining the outer lip. Parietal 

 lamella very long and high, oblique, directed towards a point, 

 above the lower palatal fold. The columellar lamella is 

 rather deeply placed, not very high, and enters horizontally 

 to the dorsal side, where the end tapers and turns upward 

 but very slightly. The upper palatal fold emerges to the 

 peristome, and with the angular lamella defines a nearly 

 closed, oval sinulus ; it enters deeply, descending a little. 

 The lower palatal is a long fold, deeply immersed, only par- 

 tially visible in a front view. The basal fold is short, trans- 

 verse to the cavity, deeply placed but visible from in front. 

 The parietal callus is rather thin. 



Length 1.5, diam. 0.85 to 0.9 mm. ; 4Vo whorls. Pretoria. 



"Length 1.41, diam. 0.83 mm." (Burnup). 



"Length 1.6, diam. 0.99 mm." (Burnup. largest specimen). 



55. NESOPFPA FARQUHARI Pilsbry. PL 34, figs. 7, 8, 9. 



Shell perforate, openly rimate, long-ovate, walnut-brown, 

 somewhat glossy. Spire convexly conic, the apex obtuse ; 

 first 11/2 whorls smooth, the rest closely, somewhat obliquely 

 rib-striate, as in N. griqiialandicd ; the latter part of the last 

 whorl flattened and having a quite small and shallow im- 

 pression behind the lip, over the upper palatal fold. Aper-
