I name this bird after Mr. Cleaver, in acknowledgment

XI .—Note on Dryotriorchis, a new Genus of Harrier Eagles 
from West Africa. By Captain G. E. Shelley. 
I received in one of my last consignments from the interior 
of Fantee an adult specimen of the Astur spectabilis of Schle- 
gel, which seems to indicate to me that we have hitherto been 
mistaken in referring this bird to the Goshawks, and that it 
is in fact an Aquiline form, with tarsi reticulated both before 
and behind. Mr. Sharpe has examined the bird with me, 
and agrees that it cannot be placed in any existing genus. 
I therefore propose to make a new one for its reception as 
follows:— 
Dryotriorchis, gen. nov.* 
Type D. spectabilis (Schl.) : Astur spectabilis, Schl. Ned.
