86 LAURIA. 



PupiLLA PUPULA (Desh.). Vol. 26, p. 214. 



Colonel A. J. Peile writes me that he suspects that Desh- 

 ayes' figures referred to this species were drawn by an artist's 

 error from Lauria bourboneiisis, not from the specimen 

 Deshayes described. Deshayes himself noticed that his figures 

 imperfectly represented his species. My figures in vol. 26, 

 pi. 17, figs. 12, 13 are the true P. pupula.

 crest. Columellar wall ornamented with a very small lamella.

Pupilla VEprevieri Pallary, Journ. de Conchyl. vol. 71, 

 March, 1928, p. 245, pi. 3, f. 36-38. 



Pallary remarks that this species, common at Laghouat, is 

 perhaps approached by P. muscorum and u-mMlicata, but 

 differs by the more numerous whorls in examples of equal 

 size and the more cylindrie form. It has much the appear- 

 ance of the Pleistocene form of Orcula of the northern Sahara, 

 from which it scarcely differs except by being of half the size. 



Laurlv zonata (Bttg.). Vol. 27, p. 79. 



Boettger's Pupa zonata, 1883, is a homonym of Pupa zonata 

 Gassies, 1869, and may be changed to Lauria albina Bttg., a 

 name given to a greenish-white mutation. If the usual banded 

 form requires a name it may be called forma zonifera. 



Laurlv wouramboulchiensis Connolly. PI. 18, fig. 9. 



Shell very small, ovate, rimate, rather solid and opaque, 

 which may be due to weathering, glossy, pale brown, with 

 darker oblique stripes on the striae. Spire moderately pro-
