362 AFRICAN NESOPUP^E. 



wall, a slightly projecting denticle very internally situate on 

 the upper portion of the columella, and a small, rather in- 

 distinct basal denticle situated well within, and rather on the 

 right-hand side of the shell. Alt. 2.25, diam. maj. 1 mm. 

 (Preston). 



Length 2.29, diam. 1.08 mm. (Burnup). 



Length 2.25, diam. 1.15 mm.; 514 whorls (Connolly coll.).

The initial I 1 /-* whorls appear smooth, but there is a very 

 close microscopic pitted-granose sculpture. The next whorl 

 has rather weak but coarse striation. On the following whorls 

 the surface appears punctate under a lens; when more mag- 

 nified it is seen to be very closely, irregularly pitted, the pits 

 very irregular in shape. There are also unequal, oblique 

 striae, conspicuous on the last whorl only immediately below 

 the suture, but noticeable on the penult and earlier whorls. 

 The striation is hardly strong enough to justify Preston's 

 term "plicate". The angular lamella is rather low, straight, 

 extending inward slightly beyond the anterior end of the 

 parietal lamella, diverging from the latter and nearly join- 

 ing the outer lip. The parietal lamella is high, oblique, and 

 enters rather deeply. The columellar lamella is deeply placed, 

 rather short, ascending very little as it enters. There is a 

 very low but fairly long lower palatal fold in a specimen in 

 Mr. Burnup 's collection (fig. 12), but none in the Connolly 

 shell (fig. 15). The peristome is thin, rather well expanded; 

 parietal callus very thin. 



The pitting, while similar to that of many Nesopupa?, is 

 unusually copious. By the characters of the teeth it is an 

 lits-ulipupa, standing close to N. barrackporensis and mala- 

 yana. Fig. 14 is from a drawing by Mr. Burnup ; fig. 15, 

 from a specimen lent by Major Connolly.

Differs from the Comoro Island type [of Pupa, minutalis 

 Morel.] by the larger shell, the last whorl more lengthened-
