the manus ; no other found on the manus. From the fact 

 that, in the last and most carefully examined specimen, 

 some of the median under coverts seemed to be lacking also 

 on the proximal part of the cubitus, it is possible that the 

 row may frequently be incomplete in that portion ; these

 manus ; overlap contrary, as well as could be made out. 



Astur sp., probably A. tousseneli. One specimen ex- 

 amined, No. 5785. 



Major under coverts forming a complete row ; overlap

Kaupifalco monogrammicas. One specimen examined, 

 No. 5628.
