122 A FIRST LIST OF THE 



" Males measured : Length, 9-2 to 9*3 ; expanse, 11 to 11*4 ; 

 tail, from vent, 3' 9 to 4*2 ; wing, 3' 7; bill, from gape, 1*3; 

 tarsus, 1*3. 



" The bill is orange yellow; the base of the lower mandible 

 and gape, dusky ■ the inside of mouth, flesh color ; iris, pale 

 yellow ; eyelid and naked skin behind eye, pale lavender ; legs, 

 dusky plumbeous ; claws, horny." 



407 bis. — G-arrulax Belangeri, Less. 



Specimens from Thayetmyo apjjear to be identical with others 

 from the neighbourhood of Rangoon and various localities in 

 Tenasserim, where this species is specially common and abundant. 



Mr. Oates says : " This is a common bird both in the plains 

 and on the hills — commoner perhaps in the latter ; goes in flocks 

 of from five to twenty, feeds on the ground, and has a very loud 

 cheerful laugh, which it utters in chords with others on the 

 slightest provocation. Their united noise is rather startling, when 

 heard unexpectedly, in some dark forest. Specimens I measured 

 gave dimensions as follow : — 



"Length, 11*2 to 11*8; expanse, 14*5 to 16*25 ; tail, from 

 vent, 4*4 to 4-8 ; wing, 4*85 to 5; bill, from gape, 1*4; tarsus, 

 1*8. The bill is black ; the gape, yellow ; the inside of the mouth, 

 flesh -colored; iris, pinkish hazel; eyelids, yellowish grey ; legs, 

 plumbeous; claws, pale horn color. I found the remains of insects 

 and two grains of rice in the stomach of one that I dissected.'''' 



This species, though recognizable at the first glance, only differs 

 from Garndax leucolophos, Hardw., in having, as Mr. Blyth 

 pointed out in 1841, the whole back, wings, sides, vent, and 

 lower tail coverts more or less ferruginous, which color in 

 leucolophos is confined to the nape and sides of the neck, 

 passing downwards across the breast, and in having the white 

 of the under parts, which in leucolophos terminates abruptly 

 at the lower part of the breast, continued some way down the 

 middle of the abdomen. 



412.— Grarrulax pectoralis, Gould, 



Some of the Thayetmyo birds differ from Darjeeling specimens 

 in having the whole upper surface somewhat paler ; the chin, 

 throat, and whole space within the pectoral band, pure white, instead 

 of more or less ferruginous ; in having the breast and flanks only 

 faintly tinged with this color ; and lastly, in having the white tijis 

 to the lateral tail feather somewhat broader. I do not know 

 whether these distinctions are constant in all specimens; in 

 dimension the birds correspond exactly. 



It is curious how the ear coverts vary in this species ; in some 

 birds they are entirely silvery white ; in others, they are mingled
