AFRICAN NESOPUP/E. 359 



ture shaped about as in griqualandica, with 6 nearly white 

 teeth. Angular lamella strong, slightly curved, joining the 

 outer lip. Parietal lamella high, oblique, penetrating to the 

 dorsal side. Columellar lamella deeply placed, strong, pene- 

 trating to the dorsal side, where it is somewhat enlarged and 

 deflected, then passing into a low callus obliquely ascending 

 the axis. The upper palatal fold is strong, curved, emerging 

 to the peristome, entering deeply. Lower palatal very high, 

 Jong, somewhat immersed. Basal fold very low and small, 

 on the basal end of the columella. The peristome is pale, 

 well expanded and a little thickened, incurved and thicker 

 in the middle of the outer margin. 



Length 1.6 to 1.65, diam. 0.9 mm.; 5 whorls.

While related to N. griqualandica, this species differs in 

 numerous particulars. The spire is somewhat longer; the 

 last whorl is far less impressed behind the lip ; the angular 

 lamella curves less; the lower palatal fold emerges much 

 further, and is as prominent in a face view as the upper. 

 Finally, the basal fold is even smaller than in griqualandica, 

 and is upon the columella. In the other species it, stands 

 deep within the base, in a face view being in front of the 

 deeply immersed lower palatal fold. 



The Abyssinian N. bisitlcata has not been directly com- 

 pared with this species. By the description and figure it 

 differs by being somewhat larger with no basal or subcolu- 

 mellar tubercle, and the teeth do not appear to be as large as 

 in farquhari.

The umbilicate shell is ovate-conic, scarcely glossy, very 

 finely and obliquely costate longitudinally (visible under a 

 lens), brown. The conic spire has an obtuse apex. The 5 

 convex whorls are separated by an impressed suture, the last 

 whorl forming a third of the total length, is narrowed towards 

 the base, with angular neck, and has two deep furrows. The
