but I have been unable to separate this race from the Himalayan 

 caedbata and am more than skeptical of its validity. See Bangs and 

 Peters, Bull. Mus. Comp. Zool., vol. 68, 1928, p. 336.

(Doi Ang Ka). 



The status of this flycatcher in our provinces is uncertain. In 1931 

 I found it not uncommon in the evergreen of Doi Ang Ka at 4,400 

 feet and collected an adult male, April 13 ; on the same mountain, at 

 4,600 feet, I took an adult female, September 1, 1935. The only other 

 example known from the area is a juvenile male from Doi Mae Kong 

 Ka, October 23, 1936. 



The adult male had the irides dark brown; the maxilla blackish 

 brown ; the mandible with the anterior half blackish brown, the basal 

 half dull fleshy orange; the rictus and interior of the mouth yellow; 

 the feet and toes dull orange-horny ; the claws horny. 



The adult of either sex has the crown and nape brownish slate, 

 changing to dark rufescent-brown on the mantle and to deep fer- 

 ruginous on the rump and upper tail coverts ; the wing feathers black- 

 ish, margined with buffy-ruf ous ; the central pair of rectrices blackish 

 brown, the others ferruginous margined blackish along the outer web 

 near the tip ; the lores buffy rufous ; a conspicuous white eye ring ; the 

 sides of the head and throat mixed slate and buffy rufous ; the chin 

 and a broad area down the center of the throat white; the remaining 

 underparts orange-rufous, sullied with brown across the breast and 

 along the upper flanks and changing to white on the center of the 

 abdomen. The juvenile is similar to the adult but has the crown and 

 mantle streaked with buffy rufous.
