56 NILS GYLDENSTOLPE, ZOOLOGICAL RESULTS OF THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 



in the Koon Tan mountain range, agree perfectly well with the descriptions of this species 

 only differing in having the bilis a little shorter than recorded and in showing a sliglit 

 variation as to the intensity of the colours. 



Specimen No. 701, which probably is a female, has the black frontal band rather 

 narrow; the ochraceous brown of the head almost reaching to the base of the bill. The 

 påle grey feathers on the upper back are tipped with ochraceous brown and the throat 

 is verv dark reddish brown and certainly not chocolate brown as in the other specimen. 

 Behind the eye there is a fairly large naked patch being black m the dried skin.

This fine bird was only observed in a fairly thick bamboo-jungle in a narrow valley 

 among the Koon Tan mountains in Northern Siarn. At this place and nowhere else a 

 small flock was met with at two different occasions. The birds were mostly seen in the 

 bamboos, now and then descending to the ground. They were fairly restless and always 

 on the move, though they probably inhabited quite a small area of land because the sur- 

 rounding jungles were of quite a different type being mostly damp evergreen forests. In 

 such kinds of forests they were never observed by me though Bingham records them 

 from evergreen forests. 



The Siamese specimens agree well with the descriptions in the literature and I 

 only want to remark that the brown colour of the feathers on the occiput and nape is 

 deeper brown than the colour of the rest of the feathers on the upper parts of the body.
