Pomatorhinus erythrogenys imberbis, Rogers and Deignan, Proc. Biol. Soc. 

 Washington, 1934, p. 91 (Doi Chiang Dao). — de Schauensee, Proc. Acad. 

 Nat. Sci. Philadelphia, 1934, pp. 3, 187 (Doi Chiang Dao). 



This species has been found in Thailand only on Doi Chiang Dao, 

 where it is rather common between 4,500 and 6,800 feet. 



It is chiefly a bird of the heavy lalang growth beneath the somewhat 

 stunted oaks that dot the highest slopes of the mountain but occurs also 

 in the impenetrable Eupatorium, which has covered abandoned hai 

 of the Musoe people. 



A specimen taken March 21 at 4,500 feet has not yet completed 

 postnatal molt. 



An adult male had the irides red ; the orbital skin plumbeous ; the 

 bill gray, with the basal half dark slate ; the feet, toes, and claws horny 

 brown. An adult female had the irides pinkish brown; the orbital 

 skin plumbeous ; the maxilla slaty, with the apical half of the culmen 

 and the edges of the commissure horn; the mandible plumbeous- 

 white; the tarsi dusky flesh, yellowish white behind; the toes dusky 

 flesh ; the soles light yellow ; the claws dusky flesh. 



This form has the entire upperparts dark olivaceous-brown, suf- 

 fused with ferruginous on the forehead, superciliary region, and ear 

 coverts ; the lores dark gray ; the sides of the throat, neck, breast and 

 belly, the flanks, thighs, and under tail coverts bright ferruginous; 

 the remaining underparts white, sometimes with a faint, narrow mus- 

 tachial line at either side of the throat; the feathers of the lower 

 throat and upper breast occasionally with blackish shafts.

The ochraceous-headed scimitar babbler is a rather rare inhabitant 

 of evergreen forest between 3,000 and 4,500 feet but is likely to occur 

 in any part of our area in which suitable conditions are found. In 

 addition to localities listed above, I have it from Huai Mae Chan 

 and Phu Kha.
