thunder or a tree falling, and often the firing of a gun will 

 cause it to cry out, making the forest resound with its power- 

 ful voice. The males make large arenas in the forest, which 

 embrace circles of a yard and a half in diameter, neatly 

 swept of all leaves and twigs. They roost in trees near 

 these spots. 



Native name " Burong Kruhi." 



Bare skin on the head cobalt-blue ; iris grey ; legs ver- 

 milion, the divisions of the scales being well marked and of 

 a paler colour.]

When Mr. Whitehead's specimens first arrived in 1887, I 

 took them to be hen birds of B. hyperythra described by 

 me from Mr. Treacher's Lawas collections in 1879. I 

 have ventured to describe them now as belonging to a new 

 species, as Mr. Whitehead feels convinced that they con- 

 stitute an adult pair of birds, and the difference in the colour 

 of the eyebrow between the Kina Balu specimens and B. hy- 

 perythra is well marked. 

 a, b. 6 2 ad. Kina Balu, March 3, 1887. 



[This Partridge frequents the thick bamboo-jungle on the 

 steep slopes of Kina Balu from 2000 to 4000 feet. It was 

 extremely difficult to obtain specimens owing to the impos- 

 sibility of getting about in the parts frequented by these 

 birds. Besides, no doubt, the rat-trapping Dusaus have had 

 something to do with their rarity. 



Iris greenish brown; bill black; skin round eye dull pink, 

 that on throat brighter; legs salmon-pink.]
