plate represented in fig. 11, is therefore probably of 

 little importance, and I propose to regard it merely as a 

 specific cliaracter, naming tlie East Greenland species Ästero-

 well-defined known species of the same genus by its feeble> 

 coarse ornamentation, its comparatively short and dip trunk, 

 and its relatively small median ventral plate.
