78 CHONDRINA. 



in a smooth, glossy protoconch, 9 convex whorls of regular 

 increase, separated by a not very deep suture, and regularly 

 sculptured with fine striae oblique from left to right, the 

 closeness of the striae emphasized on the lower whorls. Penult 

 whorl well rounded, last whorl ascending a little to the in- 

 sertion. Aperture very little oblique, a little reflected at the 

 outer margin, with two oblique internal lamellae which do not 

 reach the outer margin. Columella vertical, well rounded 

 at base and ornamented with a small denticle (angular 

 lamella) on its upper part. Finally the parietal wall carries 

 two internal folds of which the upper (parietal) is more 

 prominent than the median; these two lamellse opposite the 

 two palatal lamellae (Pallary). 



Length 7, greatest diam. 214, smaller diam. 2 mm.

 August, 1928, p. 13, fig. B. 



This species seems to be near Pupa rhodia Roth of Syria, 

 but our form has less convex whorls and the size is smaller. 

 No North African species is comparable (Pallary). 



Granopupa granum (Drap.). Vol. 24, p. 335. 



Pallary (Mem. I'lnst. d'Egypte XI, 1926, p. 40) thinks

 Granopupa granum.

Paul Ehrmann (Archiv f. Molluskenkunde, vol. 63, pp. 1- 

 28) believes that two species are commonly comprised under 

 the name avenacea. The true Pupa avenacea he believes to 

 be identical with P. cereana (" Miihlfeld " Kiister). For
