93. Tiga javanensis Ljung. — This Woodpecker was rather common in tlie 

 Northern and Central parts of Siarn, but I scarcely ever recognized it in the eastern 

 districts, and in the primeval evergreen forests it never was observed. This species 

 is very noisy but also very tame and was mostly observed in pairs.

94. Chrysocolaptes guttacristatus indo-malayicus Hesse. — This beautiful 

 Golden-backed Woodpecker was observed very often in the forests near Den Chai 

 and Pak Pan and was by no means uncommon on the Korat plateau either. It is 

 a very noisy bird, making known its presence at a great distanee by its shrill note 

 and by the great noise of its tapping. The strokes are repeated with an utmost 

 rapidity. 



All the specimens shot in Siam diiring my journey agree perfectly well with 

 the descriptions of Chrysocolaptes guttacristatus Tick. but they are all of a smaller 

 size and therefore I think the Siamese form must be referred to the subspecies 

 which has recentl}' been described by Hesse under the name of Chrysocolaptes 

 guttacristatus indo-malayicus (Mitteilungen Zool. Mus. Berlin. 6. Band. 2. Heft). 



Among my specimens there are also two birds which are showing a somewhat 

 differing colour on the mantle and the upper parts of the body. 



The typical Chrysocolaptes guttacristatus Tick. has the back, scapulars and the 

 outer surface of wings except the primary-coverts and the outer webs of primaries 

 of a rich golden olive tint, but on my specimens these same parts are briglit scarlet. 



The male has the forehead brown with white spöts but this as well as the red 

 wash on the upper parts of the body are only signs of young and immature birds.
