Ornithology of Borneo. 39 



This specimen appears to agree with Count Salvadori's de- 

 scription. Other specimens are in the Museum from Borneo, 

 but to which no title had been affixed by Mr. George Gray. 



32. Brachypodius immaculatus, sp. n. 



Brachypodius melanocephalus (Gm.) ; Salvad. /. c. p. 201 . 



a. " No. 43. 6 . Sibu. Iris cobalt-blue." 



This species is evidently rare in Borneo, as it has only 

 occurred once at Sarawak to the Marquis Doria. Count Sal- 

 vadori knows of no other instance of its capture, and refers 

 the Sarawak skin to B. melanocephalus. I find, on compa- 

 rison, that Mr. Everett's specimen agrees best with Sumatran 

 examples in the Museum ; and these I am induced to consider 

 distinct from the Malaccau species, i. e. the true B. melano- 

 cephalus, as none of the latter shows the outer tail-feathers 

 entirely yellow, as the Sumatran bird does. The Sibu skin 

 now sent is probably a young bird, as it has the back dull 

 olive-green ; but it has scarcely any trace of a dark shade on 

 the outer feather, and is nearly as bright yellow as the Su- 

 matran skins. I therefore propose to separate the latter as 

 a distinct species. 



Adult. General colour above yellowish green, more or less 

 inclining to olive, the lower back and rump mottled with 

 black, the bases to the feathers being of the latter colour, the 

 tips yellow ; upper tail-coverts bright lemon-yellow ; crown , 

 sides of head, and entire throat shining green, slightly washed 

 with purple under certain lights ; breast olive-green, gradually 

 shading off into bright yellow on the abdomen, flanks, and 

 under tail-coverts ; under wing-coverts pale yellow ; upper 

 wing-coverts olive- green, the greater series brighter and more 

 yellow; bastard wing, primary -coverts, and primaries dark 

 sepia-brown, very narrowly bordered with olive-green, the 

 secondaries blackish on the inner web, bright yellow on the 

 outer ; tail bright yellow, shading off about the middle of the 

 feather into olive-green, and thence into black, the latter 

 forming an irregular subterminal spot before a brilliant yel- 

 low tip, this dark shading becoming gradually imperceptible 

 on the outer feathers, which are consequently entirely yel-
