Youny male in moult. The first plumage has evidently been 

 brown, with broad ferruginous edges to all the feathers ; tail 

 ashy brown, with four black bands, five on the outer feather. 

 The under surface is rufous, like the adult, with remains of 

 the broad black streaks on the chest belonging to the first 

 plumage. Thighs nearly uniform rufous, with slight remains 

 of brown mottling. Total length 9 inches, culmeu 0'4, wing 

 5'7, tail 4, tarsus lv5. 



Since describing this species, I have been able to compare 

 it with specimens of A. manillensis in the Tweeddale collec- 

 tion, and I find that it is quite distinct and easily recog- 

 nizable by its rufous thighs. 



[This species seems to be confined to the more open country 

 of Kina Balu, i. e. the Dusun clearings. I saw it from 1000 

 feet to 4000 feet, but it appears to be extremely rare. In 

 fact I only managed to procure two specimens on my first 

 expedition, and in 1888, during my second visit, I only saw 

 three birds, none of which I was able to procure. I was 

 witness to a plucky fight between one of these Sparrow- 

 Hawks and a Spilornis, when the former attacked the Eagle 

 with fury and drove him right out of the tree. 



On the 30th of March, 1888, a native brought me two 

 eggs, evidently of this Hawk, which had been seen by me 

 about the locality where the nest was found. One egg 

 is of the typical Sparrow-IIawk type. Length 1*45, diam.
