276 MR. R. B. SHARPE ON [May 15, 



" Irides dark brown ; feet and legs bluish grey ; bill brown, pale 

 beneath. This bird seems to have the same habits as Mesia 

 argent awis. I saw it on the summits of Gunong Batu Putch and 

 Gunong Brumbrin at between 6000 and 7000 feet altitude. The 

 only other birds I noticed were JEthopyga %urayi, Sharpe, and a 

 large light greyish-brown-coloured Eagle ; but this latter was far 

 out of range." 



Identical with the types from Tenasserim in the Hume Collection.

In my first paper I ventured to doubt the identity of a specimen 

 sent by Mr. Wray with Siva sordida of Hume from Tenasserim ; 

 but as the 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 coloration, 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"55, tail 2'6, tarsus 0*85.

" No. 85. S $ ad. Gunong Batu Putch." 



" Irides 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 4000 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. nipalensis, a bird unknown in Tenasserim, 

 from which the Perak form differs in its fulvescent under surface, 

 and tawny-coloured lower abdomen and under tail-coverts. These 

 characters, though slight, are well established when the pair sent 

 by Mr. Wray are compared with our large series in the British 

 Museum, all of which are white below. The measurements are as 

 follows : —
