The specimens of the Common Golden-backed Three-toed Woodpecker which I 
collected in Siam all belong to the long-winged form. Curiously enough this race is also 
found in India, Bengal, Nepal and Assam and then occurs again in Java. In the Malay 
Peninsula and Sumatra a form with shorter wings occurs, which is the typical T7ga java- 
nensis of LIUNG. 
The whitish elongated stripes of the crown in the females shows a great deal of 
variation and in some specimens the whole head and nape is striped, while in other the 
occiput and nape are only faintly striped, being almost black with only a few spots. Even 
as far south as at Koh Lak in the Siamese Malaya the long-winged race was found.

During my former journey in Siam I collected specimens of the Golden-backed 
Woodpecker which belonged to the race described by Hessk under the name of Chryso- 
colaptes guttacristatus indo-malayicus. This is evidently a southern form which inhabits 
Siam north to about Lat. N. 18°. It is merely separated from the northern typical C’. g. 
guttacristatus by its size. 
In the most northern districts, where the collecting was chiefly undertaken during 
my recent trip, I only met with the typical form. Up here Tickell’s Golden-backed Wood- 
pecker was rather rare and only a few specimens were observed or obtained. 
South of Lat. N. 18° the southern race was very common in the open deciduous 
forests and was certainly one of the most characteristical birds to that kind of 
vegetation.
