grey, not light, ashy brown, and in the absence of the white 
rump, which is uniform with the lower back. 
Adult male.—(Type No. 538). Head deep chestnut, a 
black stripe from the hinder margin of the eye, broadening 
posteriorly and coalescing on the nape; lores, ear coverts, 
cheeks and sides of the head rufous brown, mottled with 
black on the lores and anterior ear coverts. Mantle, scapu- 
lars, back and upper tail coverts clear grey; wing coverts 
dark fuscous, broadly edged with green, the lesser and greater 
series tipped with bright yellow, forming a double wing bar. 
Primaries and secondaries dark fuscous brown, broadly edged 
with green on the outer webs and internally edged with white 
on the inner webs. Tail feathers as the primaries, narrowly 
edged with green on the outer webs and with no trace of 
white edgings. Under wing coverts, axillaries and angle 
of wing bright yellow; thighs mingled greenish brown and 
bright yellow ; under tail coverts white. | Whole undersurface 
pure white except the throat and fore breast, which are 
washed with cinnamon. “Iris brown, bill yellowish, brighter 
beneath ; tarsi purplish, soles yellowish.” |No. 528. ] 
Dimensions in flesi:—Total length, 107; wing, 54; tail, 
48; bill from gape, 12.5, tarsus, 17.5 mm. 
Adult female.—(Type No. 529). Does not differ ap- 
preciably from the male. 
“Tris hazel, bill horn, lower mandible yellow; tarsi 
pinkish, soles yellowish.” Total length, 107; wing, 52; tail, 
43; bill from gape, 12.5; tarsus, 18. 
Immature birds have the colours much duller, the crown 
of the head being earthy brown, the yellow wing-bars are less 
distinct and the grey of the mantle and back less pure and 
often tinged with green. 
The large series, listed below, presents certain variations 
inter se, notably in the extent and strength of tint of the 
cinnamon wash on the throat, which in some specimens is 
very much stronger than in those selected as types. Others 
have the flanks and under tail coverts slightly tinged with 
yellow.
