There seems little, if any, reason to doubt the justice of 

 Boettger's discrimination in placing P. ovampoensis, M. & P., 

 in the synonymy of this species, as Ancey 's description 

 conveys a faithful image of the shell known to South-African 

 collectors as P. ovampoensis ; but it must not be lost sight of 

 that 1| mm., Ancey's width dimension, seems excessive, Iram. 

 being the greatest width that I have observed with a height 

 corresponding to that of Ancey's type, though in one very 

 large specimen in my collection from Johannesburg {McPean), 

 whose height is 2'5 mm., the width almost equals Ancey's 

 measurement, being I'll mm. 



The figure chosen by Melv. & Pons, to represent their 

 species in the Survey is that of the Urate var. from Rusten- 

 berg (McBean), which shows more sculpture than the normal 

 form, but agrees in other respects. The shell figured 

 measures 2'25 mm. high and 1 mm. wide. 



5. Pupa dysorata, M. & P. 



The emended description given in the Survey has 

 become somewhat involved, owing apparently to two causes, 

 viz., firstly, to the authois having included intradentata as a 

 var. of this species (with which 1 cannot agree) and their 

 desire to differentiate the typical form, in its description, 

 from its supposed var. j and, secondly, to their having mis- 

 understood the position of the "deep-seated postlabial* tooth " 

 of intradentata, treating it as a columellar process instead of 

 one situate "in the gullet." In addition to this, my measure- 

 ment of the type, kindly lent to me by Mr. E. R. Sykes, is 



* Perhaps the common expression '' labial," used to express pertaining 

 to any part of the peristome or lip, is confusing, and lahral would be 

 better when the position wished to be indicated pertains to the labrum.
