BIRDS OF BRITISH BURMAH. 
generally placed in a bush or small tree at no great height from the 
ground^ and is made of small branches and leaves^ the interior being 
lined with fine twigs. It is cup-shaped^ bulky^ and very firm. The eggs 
are pure white and usually three in number. 
34. GAERULAX LEUCOLOPHUS. 
THE HIMALAYAN WHITE-CRESTED LAUGHING-THRUSH. 
Corvus leucolophus, Hardw. Trans. Linn. Soc. xi. p. 208, 1. 15. Garrulax leuco- 
lophus, Jerd. B. Lid. ii. p. 35 ; Hume, Nests and Eygs, p. 253 ] Bl. B. Burm. 
p. 407 ; Hume, S. F. iii. p. 122, viii. p. 96; Scully, S, F. viii. p. 289. 
Description. — Male and female. Like G. helangeri, but the rufous of the 
upper plumage confined to a broad collar on the upper back immediately 
below the white head. With this exception^ those parts which are rufous 
in the upper plumage of G. helangeri are in G. leucolophus plain olive-brown. 
The lower plumage is also much duller rufous. 
Bill horny black ; irides red-brown j orbital skin slaty ; feet livid 
plumbeous ; claws dusky grey. [Scully.) 
The dimensions are about the same as those of G. helangeri. 
The Himalayan White-crested Laughing-Thrush is stated by Mr. Blyth 
to occur in Arrakan. I have no personal knowledge of the bird myself, 
nor has it been met with in Arrakan in more recent times. This^ however, 
is no matter for surprise, for the whole of that division remains unexplored, 
ornithologically, to this day. 
It inhabits the Himalayas from the north-west down to Assam, and it 
is also known to occur in the Khasia hills and hill-tracts of Eastern 
Bengal. 
Its habits are precisely those of the preceding species.
