THE BIRDS OF NORTHERN THAILAND 359 



apply well enough to the present form, even to the description of its 

 notes. 



Nothing certain is known of the breeding season in our area but 

 two specimens of September 30 are in postnuptial molt. 



Examples collected by me had the irides maroon or dark red (males) 

 or orange-brown (a female) ; the eyelids edged bright yellow; the 

 orbital skin plumbeous-blue ; the maxilla dark slate with the extreme 

 tip horn ; the mandible with the basal half horny white, bluish horn, 

 or pale bluish, the apical half slaty horn or bluish horn, the tip some- 

 times horny white ; the rictus and interior of the mouth yellow ; the 

 feet and toes gray-blue or greenish plumbeous ; the claws fleshy white. 



This bird has the upperparts olivaceous-brown with an ill-defined 

 rufous nuchal collar ; the primary coverts usually more or less blackish 

 brown ; the rectrices olivaceous-brown, all except the central pair with 

 a broad buff or buffy- white tip and a broad black subapical bar ; a nar- 

 row postocular streak with the upper half buffy white, the lower half 

 black; the ear coverts silvery gray, usually streaked with black, and 

 bordered below by a narrow black mustachial streak; a conspicuous 

 black gorget, connected on the sides of the neck with both the mustach- 

 ial streak and the black portion of the postocular streak ; the remain- 

 ing underparts rufous-buff, more or less albescent on the center of 

 the abdomen. 



So extraordinary is the resemblance of this species to the following 

 that the points of difference will be dealt with in detail in the descrip- 

 tion of the black-necklaced laughing-thrush. 



I believe that Williamson's collectors took specimens of a black- 

 gorgeted laughing-thrush in the lowlands of Chiang Rai Province; 

 they should be compared with G. p. roMni Delacour.
