12 BIRDS COLLECTED IN PERAK. 
“No. 33. 6 ad. Batang Padang mountains, Perak.” 
In my first paper I ventured to doubt the identity of a spe- 
cimen sent by Mr. WRAY with Szva sordida of Hume from 
Tenasserim; but as that specimen was not adult, I refrained 
from describing it. Now that two more adult birds have been 
procured by Mr. WRay, there is no longer any doubt that the 
Perak bird is distinct, differing in its still duller colouration, 
the absence of blue on the head, which is like the back, and 
also in the absence of the ochreous brown-colour of the lower 
back and rump. ‘Total length 6 inches, culmen 0.55, wing 
2.555, tail 2:6, tarsus 0.05. 
Mesia argentauris (Hodgs.).

“No. 10. ¢@ ad. Batang Padang mountains, Perak.” 
Cutia cervinicrissa, Sp. n. 
“No. 85. ¢ 2 ad. Gunong Batu Puteh. 
‘Trides light brown; legs and feet bright chrome-yellow ; 
claws white; bill black above, grey beneath and at angle. 
It is.a rare bird, and I did not see it lower than 4,000 feet. 
It frequents the higher trees, in small parties of three or four, 
and has a loud whistling double note, repeated several times 
in succession.” 
This is a race of C. nipalensts, a bird unknown in Tenas- 
serim, from which the Perak form differs in its fulvescent 
under-surface, and twany-coloured lower abdomen and under 
tail-coverts. These characters, though slight, are well estab- 
lished when the pair sent by Mr. WRAy are compared with our 
large series in the British Museum, all of which are white 
below. ‘The measurement are as follows :—
