66 LAURIA. 



keel behind the basal lip, generally defined by an impressed 

 line. Peristome is rather broadly reflected, flattened, thick- 

 ened within, narrowed at the sinulus. Angular lamella some- 

 what triangular as seen from below, a callus spreading from 

 it toward and joining the lip-insertion. Its inward extension 

 is very short (pi. 8, fig. 15). The columella is simple (or 

 sometimes shows a faint prominence deep within). 



Length 3.25, diam. 1.6 mm. ; 6 whorls.

The short keel pinched up at the base (fig. 15) is a con- 

 spicuous feature of this shell, though somewhat variable in 

 prominence. The rather wide lip and especially the very- 

 short angular lamella are characteristic. Other species of the 

 region have the angular lamella continued much further in- 

 ward. 



No very young shells are at hand, but one of nearly 5 

 whorls shows a well-marked though low lamella on the pari- 

 etal wall, an extremely minute, deeply immersed columellar, 

 and two minute tubercular basal folds, situated as in dadion 

 but much smaller. Several specimens somewhat larger show 

 no baso-palatals, no columellar and only a very slight thread 

 on the parietal wall. 



In one adult Cape Town specimen (pi. 8, fig. 12) the an- 

 gular lamella is reduced to a little callous pad joined to the 

 lip insertion. 



This species is certainly very similar to L. cylindracea, 

 which many years ago was reported from the Cape (as Pupa 

 umbilicata Drap., by Gibbons, Journ. of Conch., ii, 1879, p. 

 282, "abundant in garden hedges about Cape Town"). Fur- 

 ther series of the immature stages should be examined, as the 

 few seen show teeth far smaller than the European species.
