98 NILS GYLDENSTOLVE, ZOOLOGICAL RESULTS OF THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 



Irides: brown. Bill: yellow with the tip blackish brown. Legs: greenish olive. 



The Great Ohinese Barbet was not imcommon among the hills of Northern »Siarn. 

 A fine series was obtained and among these birds there is a considerable amount of vari- 

 ation as to the yellowish streaks of the hind neck. In some specimens these streaks are 

 very well-marked, but in other ones they are almost absent or only faintly indicated. 



This fine Barbet inhabits the deciduous forests as well as the evergreen jungles though 

 it seems to be more sparsely distributed in the former kind of vegetation. 



Their note is a loud »pio-pio-pio », often repeated and when one bird starts calling 

 the other ones in the flock at once answer.

This species was only found in the dense evergreen jungles among the hills of North- 

 ern Siarn and was nowhere common, the commonest species being Cyanops davisoni, 

 Hume. This latter species was, however, more an inhabitat of the mixed deciduous jung- 

 les than of the damp evergreen forests. The notes of the two species' are quite similar 

 and their habits are the same too.

Irides: brown. Bill: upper mandible born colour, lower mandible dirty yellow, basc of botb mandibles 

 dirty yellow. Legs: greenish olive. 



I)avison's Blue-throated Barbet, which was originally described from the Central 

 portions of Tenasserim, was rather common among the hill-f orests of Northern and North- 

 western Siarn where a fine series was obtained. 



As compared with specimens from Ahsown in Tenasserim the Siamese birds are 

 absolutely identical and there is no difference either in size or colour.
