Sprcies and Varieties of 'Paiia. 413 



high on tlie body-wlioil. Tlie labrum is strongly lobetl above 

 the middle and bayed immediately below ; on the lower part 

 of this lobe the peristome is slightly thickened, almost to the 

 extent of forming an eleventh plait, between which and the 

 foliated extension of the lower parietal plait is formed a 

 partly covered channel to the interior. 



Height 3-77, width 2'13 mm. 



Hah. Darfjle (Burnup), also Inhluzani Mountain, Kar- 

 kloof, and Mid-lllovo, all in Natal. 



Tlie colour of the shell in life is often whitish grey. 



As a contribution towards the elucidation of this intricate 

 group, Mr. J. R. le B. Tomlin has kindly sent me a shell, 

 received by him many years ago from either Mr. Ancey or 

 Miss Glanville as representing Ancey's species. It is not 

 likely to be a co-type, as Ancey only mentions the one 

 locality, East London, and Mr. Tomlin's shell comes from 

 Albany : moreover, it does not agree in detail with Ancey's 

 description ; I can therefore only consider it a second variety. 

 I am indebted to Mr. W. L. Radford for a further example, 

 agreeing in all essentials with Mr. Tomlin's shell, which he 

 collected for me at East London. As, therefore, my only 

 two specimens come from different localities, a geographical, 

 varietal name seems inexpedient; I therefore propose to 

 associate it with Mr. Tomlin's name : — 



Var. tomUni, new var. (PI. X. fig. 7.) 



Shell like var. darglensis, but larger and more conical, with 

 peristome less effusively expanded, callus not extending so 

 high on the body- whorl, and aperture not so much closed by 

 plaits. The lobe and sinus of the labrum are less developed 

 and the thickening of the peristome on the lower part of the 

 lobe "almost forming an eleventh plait" is entirely absent, 

 its place being taken by the first labial plait. The lower 

 parietal plait is shorter and its foliated extension to ttie peri- 

 stome much less effuse, leaving the sutural canal more open. 

 In place of the two inrunning plaits on the base of the peri- 

 stome there is only one, about equidistant between the lowest 

 labral and lowest columellar plait. The colour of the 

 varietal type is almost wiiite, that of the co-type pale brown. 



Height (type of var.) 4-0, width 2*11 mm. 

 „ (iiadford^'s specimen) 4*17, width 2*27. 



Bab. Albany (Tomlin), East London (Radford), both in 

 the Cape Province. 



In comparing these varieties with Ancey's description it 

 must be borne in mind that probably what that author treats
