Diagnosis. — Carina smooth, subcarinated, witli the lower 

 part ot the valve unusually wide, and its upper [lart almost 

 always bowed outwards. Scutum with the whole tergo- 

 lateral portion bent almost at right angles to the remainder 

 of tlie valve. Tergura 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 a(kl the scutum and tergum. The scutum and 

 tergnm doubtfully referred by Peron to this species carae 

 from the Cenomanian chalk, and are almost certainly refer- 

 able to P.glaber. 



Distrihution. — !MiddIeNeocomian,IIilsconglomerat:Esscn- 

 on-t he-Ruhr, Westphalia. 



Muttrial. — Several valves of this species from the type- 

 locality are in the Geological Department of the British 

 Museum, and comprise eleven carinic, regis^tercd 1. 11U31,
