PUPOIDES, WEST AFRICA. 139 



nit id-id us P., all of which I could compare in my collection, 

 the present species is the most cylindric of all, being longer 

 and more cylindric than B. canspectus Hutt., and its whorls 

 increase so slowly that the three last differ but little in height ' ' 

 (Bttg.). 



"B. canspectus Hutton", mentioned by Boettger, is appar- 

 ently a label error for ccenopictus, as Hutton did not describe 

 any conspectus. 



Possibly the specimens reported from Jansonville are the 

 same as those which I have referred to ccenopictus. Boettger 's 

 original figures are copied by photography in pi. 14, figs. 

 10, 11. 



A series from Swakop Valley in the S. "W. African Protec- 

 torate, sent by Mr. Burnup, show a somewhat less cylindric 

 form than Boettger 's figures, though they are more so than 

 P. ccenopictus. They differ very little from the narrower 

 examples of P. senegalensis. One measures : length 5.4, diam. 

 2.6mm. (pi. 17, fig. 8). 



23. PUPOIDES MINUSCULUS (Mousson). PL 14, fig. 5. 



Shell minute, rimate-perforate, elongate-ovate, without 

 gloss, brownish-corneous. Spire convexly conic, regular, the 

 summit somewhat obtuse; suture moderately impressed. 

 Whorls 5, quite convex, the last % the length, oval, rotund, 

 little ascending, a little compressed about the rimation. 

 Aperture nearly vertical, lunate-oval; peristome acute, white, 

 narrowly reflected, margins little approaching, joined by a 

 thin layer which has a grain above at the insertion; right 

 margin less, basal more curved ; columellar spreading, the 

 columella deep within. Length 3, diam. 1.8 mm. Ratio of 

 whorls 2:1; ratio aperture 3: 2 (Mousson). 



South Africa. Ovampoland: Ku-Ganab, southeast of On- 

 donga (Schinz) ; Hoeis (Hermann) ; Sodanna (Passarge). 

 Bechuanaland : Meno a kwena, fossil (Passarge).
