I obtained a single specimen of this small Eagle in Borneo. 

 It had seized a pigeon, which it was devouring when I shot it. 

 Wing 13 inches, the point 4 inches ; tail 7'5 inches ; tarsus 

 2*5 inches ; middle toe 1*625 inch, inner toe 1 inch,

Supra fuscus, subtus albo-rufescens ; alis rotundatis brevibus ; 

 Cauda trifasciatd ; digitis parvis. 



Above brown, the head paler, with a black occipital crest, white- 

 tipped ; wings rounded, the fourth and fifth quills longest ; tail 

 rather long, smoky-brown, with three blackish bands, one at the 

 extremity and two towards the base ; beneath white, tinged with 

 rufous ; a dark patch over the eyes and lores. Total length 

 19 inches; wing 11 inches, the tip 2 inches; tail 8'5 inches;

 inch. The middle toe is feathered nearly to the first joint. 



Hab. Borneo. 



I possess a single imperfect specimen of this bird, which 

 diflfers so much in its proportions and size from the other species 

 that I am compelled to consider it distinct.
