FAUXULUS. 239 



ical crevice. The aperture is higher than wide, relatively 

 small, rounded. On the parietal wall there are two high, nar- 

 row folds, a third on the coluniella, and three smaller ones 

 deep in the palate. Peristome is sharp-edged, ends separated, 

 hardly thickened. Interior flesh-colored, folds and peristome 

 white. Alt. 6y 2 , breadth 2 lines. Zoetendals Valley, in the 

 Zwellendam District of Cape Colony, on plants, collected by 

 Dr. Krauss (Kuester). 



Pupa ovularis Kurr, KUESTER, Syst. Conch. Cab., Pupa, p. 

 10, pi. 1, f. 16-18; not P. ovularis Lamarck. -- Pupa kurrii 

 Krauss, PPEIFFER, Symbolae, ii, 1842, p. 54; Monographia, ii, 

 331. 



Pfeiffer re-named this form, being under the impression 

 that the name was preoccupied by Pupa ovularis Lamarck. 

 This was not the case, since the earlier ovularis was originally 

 described as a Bulimus. Pfeiffer 's description differs from 

 Kuester 's by attributing two teeth to the palatal wall, instead 

 of three. Kuester 's individual was probably abnormal or un- 

 usual by having an interpalatal plica developed. 



Figs. 5, 7 and 9 agree in the tapering spire, and probably 

 belong to one race, which will be called F. c. ovularis. 



Pupa fonticola Deshayes. PL 39, fig. 9. The shell is ob- 

 long-conic, cyliudroid, acute at the apex, sinistral, gray- 

 bluish, the base having a brown band ; obsoletely and obliquely 

 striate ; spire acuminate, a little convex ; whorls 11, narrow, 

 at first flat, the rest very slightly convex, the last whorl very 

 short, the base convex, rimate and perforate. Aperture small, 

 semilunar, contracted laterally, brownish within, 5-toothed : 

 three subequal teeth on the superior wall, two parallel in the 

 left margin, one deeper, lamellar. Length 10, diam. 5^ mm.

 fluv., ii, 1851, p. 220, pi. 156, f. 26-28. 



The very distinct and narrow brown band at the periphery 

 of the last whorl is chiefly visible in the back view given by 

 Deshayes. The spire tapers more acutely above than in speci- 

 mens of capensis seen, being similar to ovularis in this re- 

 spect. That M. Verreaux found it in the water was doubtless 

 accidental.
