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, culmen 
04, wing 5‘7, tail 4, tarsus P75. 
Since describing this species I have been able to compare it with specimens of A. manillensis in the 
Tweeddale collection, and I find that it is quite distinct and easily recognizable 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 w r as 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 out of a 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 wdiere the nest was found. One egg is of the typical Sparrow-Hawk type. 
Length 1*45, diam. 1T6 in. Colour greenish white, with the usual reddish blotches towards the larger 
end. The second egg is nearly spotless. Length 1*5 diam. T2 in.] 
6. Spizaetus limnaetus (Horsf.). 
[In Labuan this species is resident and breeds on the island. A female with the under surface white, 
and striped with brown, w T as shot from the nest on the 15th of December. She wos paired with a black 
male, and the nest contained one large white egg, which has since been unfortunately broken. Another 
pair, from Tampassnk, with a nest and eggs, the male of which is nearly uniform chocolate-brown, while 
the female is light brown below, streaked with black.] 
7. Lophotriorchis kieneri (Geoffr.). 
? ad. Kina Balu, March 20, 1887. 
[This is a beautiful adult bird, and was the only one I saw in Borneo. Mr. Wallace had previously 
procured a specimen in Sarawak, but no one else seems to have met with it. I consider it to be probably 
only a visitor to Borneo during the N.E. monsoon, as, had it been a resident, I think I must have noticed 
it on other occasions. My single specimen was procured on my first expedition to Kina Balu at a height 
of about 1000 feet. Iris dark brown ; feet and cere pale chrome-yellow.] 
8. Neopus malayensis (T.). 
a. $ ad. Padas Biver, June 14, 1885. 
b. $ imm. Tampassuk, Feb. 15, 1886. 
[The male from the Padas had the iris hazel and the feet and cere king’s-yellow. The younger 
male has the soft parts exactly as in the old bird. Not seen on Kina Balu, but frequently observed on 
the large plains on the sea-coast, where I have seen it beating low over the liill-sides.] 
9. Spilornis bacha (Daud.). 
$ ad. Kina Balu, March 11. 
This is apparently the first real instance of the occurrence of the species in Borneo ; I have compared 
it with Javan specimens and find that they cannot be separated. 
[This Serpent-Eagle replaces the small Spilornis pallidus in the higher regions of Kina Balu. I did 
not meet with it below 3000 feet, and even at this altitude it w r as scarce. The crop of the specimen shot 
was full of lizards and snakes, and I noticed it frequently beating along the dried-up beds of rivers, 
where it could easily obtain the various rock-lizards on which it preys.] 
10. Spilornis pallidus, Walden. 
a. S ad- Benkoka, Maruda Bay, Oct. 2, 1885. 
b. S ad. Tampassuk, Feb. 26, 1886. 
[This species is more frequently met with in the jungle than in the open country. I do not remember 
observing it above 1000 feet on Kina Balu, but my specimens were destroyed by insects.]
