Diagnosis.—Carina smooth, subcarinated, with the lower 
part of the valve unusually wide, and its upper part almost 
always bowed outwards. Scutum with the whole tergo- 
lateral portion bent almost at right angles to the remainder 
of the valve. Tergum with the upper carinal margin un- 
usually short, being about one-third the length of the lower 
carinal margin. 
Remarks.—Hitherto this species has been represented 
by the carina only. It is therefore an important addition 
to be able to add the scutum and tergum. The scutum and 
tergum doubtfully referred by Peron to this species came 
from the Cenomanian chalk, and are almost certainly refer- 
able to P. glaber. 
Distribution.—Middle Neocomian, Hilsconglomerat: Essen- 
on-the-Ruhr, Westphalia. 
Material.—Several valves of this species from the type- 
locality are in the Geological Department of the British 
Museum, and comprise eleven carine, registered I. 14081,
