NiSAETUS ALBO-NiGEE, BL, young ■? 



From Malacca, and perfectly distinct from any of the other species of the group, though 

 approaching nearest to N. cristatellus in the young plumage, being, however, much smaller. 



This bird has the head crested as in N. cristatellus; the feathers forming the crest being 

 black, slightly edged with dirty white at the tips ; all the underparts white, washed with light 

 fulvous, darkest on the flanks and thigh-coverts ; upper parts brown, lightest on the head ; 

 two middle tail-feathers similarly brown, with three distinct broad black transverse bars, and a 

 fainter one near the base of the tail ; the outer rectrices lighter on their inner webs, and all the 

 feathers edged with dirty white at the tips ; under surface of the tail light, the black bands beino- 

 seen distinctly only through the two middle and the two outer tail-feathers: primaries deep 

 brown ; outer webs of the first black : wings graduated ; first quill three fourths the length of the 

 second, which is shorter than the third, while the fourth and fifth are nearly equal, though the 

 fifth is longest ; the underside of the wing is white near the flanks and shoulders, while the 

 lower part is barred with black : the tarsus is closely feathered to the base of the toes. The 

 whole form is strictly that of a Kisaetus.
