238 PAUXULUS. 



An inspection of specimens from several localities, and of 

 the published figures, gives one the impression that a number 

 of local races might be recognized to advantage, the shape of 

 the spire, the size and color offering differential features ; yet 

 Mr. Burnup, a careful student of African Pupillidae, believes 

 that the varietal names kurrii and pottebergensis "seem 

 scarcely worth perpetuating, as all intermediate forms, as well 

 as other forms with attributes of equal varietal value, exist. " 

 In any case, this is a question for naturalists on the ground, 

 who should begin by securing topotypes of the old species 

 collected by Dr. Krauss. 



(a) A color- variety having the summit, a band below the 

 suture, and the base ochre-colored has been collected at Buf- 

 felsfontein, Cape Point, where shells of uniform pale flesh- 

 color and grayish white are also found. This appears to be 

 typical capensis. Examples received from Mr. Connolly are 

 drawn in figs. 1, 2 and 3. They measure, length 7.7, diam. 3.3 

 mm., 10 whorls ; 7.1 x 3.5 mm., 9 whorls ; 9 x 3.5 mm., 10% 

 whorls. 



(&) Specimens collected by Mr. Jas. Crawford at Port 

 Elizabeth (pi. 39, fig. 4) are all small, from length 6, diam. 

 2.7 mm., 9 whorls, to 5 x 2.6 mm., 8% whorls ; being therefore 

 about the size of pottebergensis. 



(c) Another form, the exact locality not known, meas- 

 ures, length 9.4, diam. 4.5 mm., 8% whorls (pi. 39, fig. 7). 

 It has the large size and tapering spire of var. ovularis (fig. 5) 

 and the probably identical form described as fonticola (fig. 9). 



Figures 1-4, 7, are drawn to the same scale. Fig. 6 is copied 

 from the original figure of capensis. 



Translations of the original descriptions of forms subordi- 

 nated to F. capensis follow. 



Pupa ovularis Kurr, Kuester. PL 39, fig. 5. Sinistrally 

 coiled. The shell shows similarity in conformation with Buli- 

 mus ventricosus, but has an altogether peculiar aperture. It 

 is bluntly conic, somewhat convex, thin-walled, narrowed 

 below, finely striate with matt luster, yellowish brown, the 

 apex whitish; the 9 whorls are rather oblique, very low, 

 almost fiat, joined by a simple, thread-like suture, the last 

 suddenly contracted, prolonged below, with a narrow umbil-
