the orange-scarlet tippet beautifully developed and no doubt 

 capable of being erected to form a conspicuous ruff round 

 the head, when the bird is showing off to the females. There 

 seems to be no possible reason for regarding this very 

 distinct bird as a subspecies of X. aureus Linn., from the 

 Arfak Mountains. The latter has a much stouter bill ; the 

 cheeks, chin, and throat black ; the mantle more orange ; 

 the lesser wing-coverts black and the inner secondaries 

 devoid of black tips, only the first five being rather narrowly 

 marked with black at the extremity. 



A second adult male (No. 1339), which had probably 

 recently assumed adult plumage, has blackish spots on the 

 lores and just below the ears; the thighs are also blackish 

 instead of yellow. The third adult male (No. 1338), which 

 has been given to the Tring Museum, has the inner webs 

 of the innermost secondaries black along the terminal half ; 

 this is probably a mark of immaturity. 



The adult female (No. 1247) has the upperparts, in- 

 cluding the top and sides of the head, brown tinged with 

 olive, the throat whitish and the underparts pale yellow, the 

 feathers of the chest being margined with brownish. The 

 wings are brown like the back ; the shafts and inner webs 

 of the quills viewed from below are bright yellow. Wing 

 135 mm. 



A young male, apparently in second plumage (No. 1353), 

 resembles the adult female, but the chest-feathers are 

 brownish, not yellow edged with brown ; and among the 

 feathers of the mantle there are a few orange-red plumes 

 making their appearance and probably heralding the third 

 plumage. 



Two males (Nos. 1337 & 1352) apparently coming out of 

 the third year's plumage, resemble the adult male as regards 

 the head, tippet, and underparts, but the back, rump, upper 

 tail-coverts, and wings are still in the plumage of the third 

 year, being brown strongly washed with olive on the back 

 and on the webs of the secondaries. 



This splendid Bower-Bird is new to the British Museum. 



The specimens figured are S No. 1325 and ? No. 1247.
