Type. Proximal plates of pectoral appendage ; Geological Society 

 of London. 



An imperfectly known species, of moderate or large size. Tu- 

 bercles upon dermal plates nearly always confluent, though often 

 displaying indications of the original stellate bases. Proximal 

 segment of pectoral appendage long and slender. 



The so-called Bothriolepis giganteus is now regarded by Traquair 

 (in litt.) as the adult of this species.
