My specimens had the irides dark brown; the edges of the eyelids 

 fulvous; the bill light pinkish brown, with tip and apical half of 

 culmen blackish brown, the edges of the commissure fleshy, the rictus 

 fleshy white ; the interior of the mouth pink ; the feet and toes light 

 pinkish brown ; the claws blackish brown. 



The adult male has the upperparts brownish gray or grayish 

 brown, with a more or less distinct rufous-buff nuchal collar and bold, 

 deep buff markings on the scapulars and innermost secondaries; the 

 feathers of the back vermiculated with blackish but without distinct 

 black streaks; a buff -washed white band across the four outermost 

 primaries near their center; the two outer pairs of tail feathers en- 

 tirely white except for a mottled brown area at the tip; a white 

 throat patch ; the breast colored like the back ; the remaining under- 

 parts buff, narrowly barred with blackish brown, the bars disappear- 

 ing posteriorly. The adult female lacks white markings in the wings 

 and tail but may be recognized by its unstreaked back and general 

 resemblance to the male. 



CapHmulgus monticoVus is, in my opinion, merely a continental 

 representative of the Javanese G. affinis, to which it is linked by C. 

 griseatus (Luzon), C. mindanensis (Mindanao), and C. propinquus 

 ( Celebes) . .. v n 'f?l 



In the absence of comparative material, I can form no opinion on 

 the validity of Stuart Baker's burnwnims, which Ticehurst (Ibis, 

 1939, p. 32) considers to be unrecognizable. In the event that it 

 prove distinct, our birds must be known by Baker's name.

The swiftlet is recorded only from a few of the higher peaks of 

 Chiang Mai Province. I took three examples at 4,600 feet on Doi 

 Ang Ka, April 20, 1931, but frequently saw it there as high as 5,500 

 feet. De Schauensee collected one at 4,600 feet on Doi Chiang Dao,
