Our larger shortwing is fairly common on Doi Ang Ka from 6,000 

 feet to the summit but is known from no other Thai locality. 



I found it only in the dense, moss-bedecked cloud-forest of these 

 high altitudes, feeding on the ground beneath the tall ferns or, at 

 small clearings, in the Eupatorium which had somehow found its way 

 thither. In the deep shade it appears to be a black bird with a white 

 crown. 



Specimens of either sex had the irides brown ; the eyelids plumbeous- 

 blue ; the bill black ; the feet, toes, and claws wood brown. 



The old male has the lores and the feathers immediately about the 

 eye black ; a conspicuous, long white supercilium ; the rest of the plum- 

 age deep indigo-blue, the feathers of the center of the abdomen and 

 the under tail coverts more or less distinctly margined with ashy gray. 

 The adult female has the forehead, lores, and an indistinct super- 

 ciliary line bright ferruginous, this color changing gradually to the 

 olivaceous-brown of the remaining upperparts; the remiges and rec- 

 trices dark rufous; the underparts dull gray-brown, albescent on the 

 abdomen ; the under tail coverts ferruginous-buff. Between the Juve- 

 nal and adult plumages, the male assumes a dress similar to that of the 

 adult female, from which it may be at once distinguished by the 

 white eyebrow.

This little bird probably occurs in suitable territory throughout 

 the provinces west of (and including) the Khun Tan chain. Smith 

 collected four examples on Doi Langka; I found it common on Doi 

 Ang Ka between 4,400 and 4,900 feet and the members of the Asiatic 

 Primate Expedition took one there at an elevation of 6,000 feet. The
