Stachyris nigriceps yunnanensis, Greenway, Bull. Mus. Comp. Zool., 1940, p. 

 170 (Doi Ang Ka, Doi Nang Kaeo). 



The gray-throated babbler is found chiefly in the mountain ever- 

 green between 3,500 and 5,500 feet (usually above 4,500 feet) but, in 

 districts of lowland evergreen, occurs also at feeble elevations. It 

 seems to be generally, although locally, distributed throughout our 

 provinces. 



It is seen in flocks, often with Alcippe spp. and other small babblers, 

 in the densest undergrowth, moving with such rapidity through the 

 tangled vegetation that it can rarely be observed satisfactorily. 



Examples with the gonads greatly enlarged were taken in Nan Prov- 

 ince, March 29 and April 5. A specimen in full juvenal dress was col- 

 lected June 22 and others, in postjuvenal molt, between August 17 and 

 September 2. 



My birds had the irides tan ; the maxilla black ; the mandible plum- 

 beous, with the extreme tip blackish horn ; the feet and toes light green- 

 ish brown ; the claws light horny brown. 



This species has the crown black, each feather fringed with ashy 

 white to give a streaked appearance ; the center of the nape and the re- 

 maining upperparts olivaceous-brown, more rufous on the wings and 

 tail ; a supercilium, white immediately above the eye, ashy white poste- 

 riorly, separated from the crown by a conspicuous black line, which be- 

 gins above the eye and reaches the side of the nape, where it is divided 

 from the olive-brown portion of the nape by an edging of ashy white ; 

 the ear coverts light brown ; the throat gray, bordered at each side by a 

 short grayish-white mustachial streak; the remaining underparts 

 rich buff, brightest on the breast and washed with olivaceous-brown 

 along the flanks. 



JS. n. yunnanensis is distinguishable from coltarti in having the un- 

 derparts paler and the throat patch uniformly gray, not blackish poste- 

 riorly ; from davisoni, in having the dark markings of the head black, 

 not blackish brown, thus contrasting more with the pale edgings of the 

 feathers.
