LESSER WHITE- CROWNED THRUSH. 285 
Independent of tlie great difference in the sizes 
of this and the last, the present species may he 
known by the back and wing-covers being dark 
cinereous instead of brown, by the white of the 
crown being confined to a stripe down its centre, 
and by the rufous of the throat being extended 
round the back of the neck, so as to form a nuchal 
collar, which borders the termination of the black 
and white on the head ; there is also no brown on 
the chin, and the sides of the head and ears are deep 
black, instead of brown. The wings only reach as 
far as the upper tail-covers ; the bill is black, and 
the feet dark brown. 
This species measures from seven inches and a 
quarter to seven and three-quarters, according to the 
greater or less contraction of the neck. On each 
side of the head is a broad stripe of black, which com- 
mences in front of the head at the nostrils, and ex- 
tends to the nape, — it includes not only the ears hut 
the eye, which is placed nearly in the middle of it ; 
following this, and in the centre of the crown, is a 
white stripe which terminates at the nape, but which 
leaves a black space between it and the eye ; these 
stripes are cut off, as it were, from the grey colour of 
the back, by a collar formed by a continuation of the 
rufous on the neck. The back, wing-covers, and 
edges of the quills are deep cinereous, which colour 
graduates into buff-orange on the upper tail-covers. 
The whole of the under plumage, from the chin 
downwards, is bright and uniform buff-orange or 
orange-rufous, and the lateral tail-feathers are the
