 the thoracic pleura are blunt, but this feature is hardly a generic 

 criterion.

Raymond suggested that this species might go into Athabascia, 

 ( = Clavaspidclla) , but it will be observed that, except for the exten- 

 sion of the pleural furrows to the margin of the pygidium, it has no 

 feature in common with ClavaspidcUa.
