vertieal aperture is rounded and contracted by 5 folds: the 

 right one of the parietal wall is connected with the termina- 

 tion of the outer lip; the second is more deeply placed* 

 There is a high columellar lamella and two palatal folds, of 

 which the upper emerges to the peristome and unites there- 

 with, the second disappears before reaching it. The peri- 

 stome is moderately expanded and thickened within, the 

 right margin bent inward by the upper furrow which cor- 

 responds to the upper palatal fold. Length Ivg, diam. \ f

 maszen. and on the Keren Mts., Bogos. under rotten leaves, 

 wood and stones (Jickeli).

No Abyssinian specimens are at hand, and as Mr. Burnup 

 has observed. Jiekeli's figures do not agree in proportions 

 with his measurements. The latter indicate a shell propor- 

 tioned like the following form. 



56a. X. bisulcata rbodesiana n. subsp. PL 34, figs. 5, 6. 



The shell is more elongate and cylindric than in N. bisul- 

 cata according to Jickeli *s figures, the penult whorl equalling 

 the last in diameter. The whorls are strongly convex, the 

 striation less regular and not so strong as in 3T. griqualandica. 

 Latter part of the last whorl is a little flattened laterally 

 and close behind the outer lip there is a short furrow above 

 the middle. The teeth are much smaller than in griqualan- 

 dica and farquhari, the palatals especially being shorter. No 

 basal or subcolumellar fold is present. 



Length 1.85, diam. 1 mm,; 5 whorls. 



Rhodesia: Victoria Falls (Connolly). 



A specimen of this form was sent with N. griqualandica. 

 It differs so much in contour from Jiekeli's figures that, tak- 

 ing the locality and faunal zone into consideration, I am dis- 

 posed to give it subspecifie standing. A T . bisulcata is figured
