Foraminifera and Ostracoda. 231 



The occurrence of this species in the Cretaceous of South Africa 

 is extremely noteworthy, for up to the present it had been known 

 only from the Gault of Folkestone, where it was first discovered by 

 Reuss, and found later by Rupert Jones and the writer. At Folke- 

 stone P. carpcnteri occurred both in the Lower and Upper Gault.

This is one of the depauperated varieties of the group of P. clcgans 

 which seems to be restricted to the Mesozoic formations — the Jurassic 

 and Cretaceous. It has been found in the " Ornatus " clays of 

 Russia (Callovian), the basal beds of the Albian in North Germany, 

 the Cretaceous marls of the Upper Bavarian Alps, the Gault of 

 Folkestone, England, and the Navesink marls (Upper Cretaceous) 

 of New Jersey, America. P. reticulata is represented by small but 

 otherwise typical specimens in the Cretaceous of East Pondoland, 

 and in the washings is quite common.

Specific Character. — Test discoidal, gently convex on the superior 

 face, whorls slightly terraced ; inferior surface strongly convex. 

 Peripheral edge and sutures limbate on the upper side ; sutural 

 margins of chambers on the lower surface greatly thickened and 

 having a stellate arrangement, the rays thickest at the umbilicus. 

 Outer whorl with about eight chambers. Both surfaces ornamented 

 with fine circular or polygonal pittings. Peripheral edge fairly
