leaves like a titmouse and constantly uttering a characteristic mewing 

 note. 



The male of a mated pair, with the gonads greatly enlarged, was 

 taken on Doi Ang Ka at 4,500 feet, April 11. Postnuptial molt is 

 shown by specimens collected between July 10 and September 1. 



Adults had the irides gray-brown; the bill blackish, plumbeous 

 at the base of the mandible ; the feet horny gray, the toes somewhat 

 darker ; the claws horny. 



This form has the upperparts golden olive-green, more strongly 

 suffused with golden on the rump and upper tail coverts and some- 

 times also on the front and supraloral region; the remiges and 

 rectrices dull black, edged with golden olive-green; a very con- 

 spicuous eye ring of silky white feathers, narrowly interrupted at the 

 anterior corner of the eye by a patch of black which covers the lores 

 and the anterior infraocular region and sometimes continues as a 

 narrow line to the posterior corner of the eye; the chin, throat, 

 uppermost breast, and the under tail coverts golden-yellow; the 

 remaining underparts ashy, albescent toward the center of the ab- 

 domen, and always with a narrow and indistinct mesial streak of 

 golden-yellow (or at least an indication of it on the center of the 

 belly). 



Our bird is neither palpebrosa (Bengal), which has the underparts 

 vinaceous-ashy and the mesial streak of exceptional occurrence, nor 

 auriventer (Tavoy), a coastal form that has the mesial streak broader 

 and brighter and the rectrices almost without olive-green edging. 

 The name mesoxantha is probably applicable to all Burmese examples 

 called palpebrosa by recent authors.

(Doi Nang Kaeo). 



I place under this name two females taken by me on Doi Chiang 

 Dao at 6,200 feet, March 19, 1937; the two males and three females 

 collected by the Asiatic Primate Expedition on Doi Nang Kaeo, 2,800 

 feet, between April 8 and 15, 1937 (examined) ; and, with reserva- 

 tions, a juvenile male from Phu Kha, 4,500 feet, April 16, 1936. On 

 Phu Kha, at the borders of Laos, it may well be the breeding race; 

 to Doi Chiang Dao, where mesoxantha also occurs, it is merely a 

 rare winter visitor; its status on Doi Nang Kaeo is unknown but, 

 if it occur only in winter, it is at least remarkable that not one of
