The present race inhabits, in our area, the deciduous forest of the 

 provinces west of, and including, the Khun Tan chain, not ascending 

 the mountains beyond the altitudinal limit of the pa daeng. Its range 

 scarcely impinges upon that of 7neridionalis, and the specimen recorded 

 by me (1936) as having been taken on Doi Suthep at 2,700 feet was, in 

 fact, collected on the Chiang Mai plain, where it was almost certainly 

 with a flock of its own kind. I took other examples at Ban Samoeng, 

 Doi Chiang Dao, and Muang Fang. 



The flocks of G. m. fuscatus sometimes accompany those of G. I. 

 diardi through the dry forest ; the two species seem to have identical 

 notes and habits. 



Specimens in postjuvenal molt have been taken on July 14, 22, and 

 23; others in postnuptial molt between August 4 and December 24. 

 The plumage becomes astonishingly worn and bleached from contact 

 with the rough leaves among which the bird dwells. 



An adult female had the irides creamy yellow ; the orbital skin slaty ; 

 the bill blackish brown, with the edges of the commissure horny brown 

 and the tip horny white ; the interior of the mouth plumbeous ; the feet, 

 toes, and claws fleshy white. 



This species is smaller in all its parts than G. p. meridionalis, but 

 the size difference is not apparent in the field. G. p. meridionalis has 

 the ear coverts usually streaked with black and bordered below by a 

 distinct black mustachial streak, while f meatus has them plain silvery 

 gray, with no black line to separate them from the buffy-white throat ; 

 meridionalis has the primary coverts more or less blackish brown, 

 while fuscatus has them olivaceous-brown like all the other coverts; 

 meridionalis has the irides red and the eyelids edged with bright yel- 

 low, while fitscatus has the irides yellow and the eyelids without 

 conspicuous color. 



De Schauensee seems to have named baheri as a result of comparing 

 fresh Thai material with "foxed" Burmese and Indian skins. I find 

 much individual variation in my series but no constant character by 

 which they can be separated from fuscatus.
