absorbs tlie inaterial from the inner ends of the lamellaBj and 

 adds it to the outer ends ; for the youngest of the shells, con- 

 sisting of no more than three whorls, and measuring only half 

 a millimetre in greatest diametei", is furnished with a complete 

 set of lamellte; yet in the adult none of the folds, or at least 

 none of those on the outer wall, extends inwards more than 

 *04 mm. from the peristome. 



The specimen from Kingwilliamstown is slightly larger than 

 the t3"pe, and is the largest shell of the species that I have 

 seen, measuring 0'79 mm. in height and 1'32 in width. It' 

 belongs to the collections of the South African Museum, Cape 

 Town. 



Endodonta [Endodonta (Afrodonta)] inhluzaniensis 

 n. sp. PI. XXIV, figs. 14-17. 



Shell minute, depressed conic-oval with convex spire 

 slightly raised, deeply and moderately widely umbilicate, 

 pale horn-colour, thin, translucent, dull; whorls 4, narrow, 

 convex, the last rounded at the periphery, deeply impressed 

 at the sutures, closely microscopically lirate, except the lirst 

 li, which are smooth ; aperture nearly erect, crescentic, with 

 a distinct callus connecting the ends of the thin peristome, 

 which is slightly thickened towards the columellar margin. 

 The aperture contains two strong whitish in-running lamellae 

 or folds as follows: one on the basal wall, rather short, set 

 back a little from the peristome; and one on the outer wall, 

 longer a»d set further back. 



Height 0-86, width 1*44 mm. 



Hab. — Inhluzani Mountain, Natal (Burnup). 



Only four specimens of this species have yet been found, 

 and all were dead. The pale colour and dulness of the type 

 are probably due to the influence of the weather, for one 

 specimen, rather smaller than the type, is darker and shows 

 the silky lustre of the other species described in this paper. 

 The internal folds of the type can be seen through the shell 

 (as shown in figs. 16 and 17) only by wetting it, but in the
