Kurrioviyum, Lepchas (Jerdon) ; Awon-Awon, Java. 
Adult male and female. Length 10’0 to 10-3 inches; wing 4-8 to 5’3; tail 5’4 to o’ 7 (to tip of penultimate), 
middle feathers about 1'5 shorter; tarsus 0’55 to 0’65 ; anterior toe 0’6, claw (straight) 0’25; bill to gape 0 J 
to 0’95. 
Tris brown ; bill black ; gape and inside of mouth orange-red ; legs and feet blackish or deep reddish black, the edges 
of the tarsal scales whitish ; claws black. 
Plumage above and beneath black, with a blue and a green gloss or sheen, brilliant above and subdued on the lower 
surface ; the head and tail have the blue lustre the strongest, and the back and wings green (in some speci- 
mens there are one or two white feathers on the occiput) ; the lateral tail-feathers are tipped and crossed with 
slanting bars of white, the penultimate has a series of white spots adjacent to the shaft, and all therectrices a line 
whitish edge at the base ; the under tail-coverts, which are glossed more highly than the breast, are tipped and 
banded with white, and there is a conspicuous white tuft on the outer thigh-coverts. 
Young. Iris red-brown; legs paler than the adult. In the first plumage the upper and lower surface have white 
tips to the feathers ; the wing-coverts and reetrices are similarly tipped, and some of the underlying upper tail- 
coverts are barred as well ; the head, back, and wings are less glossed than the adult, and the under surface is 
brownish black; the tail is more barred, the penultimate being thus marked instead of spotted, and the next 
feather has a series of median white marks. In this stage the tail is rounded, the penultimate being shorter than 
the adjacent inlying feather. 
With age the spots disappear from portions of the upper surface, remaining longest on the upper tail-coverts, and some
