The specimens of the Common Golden-backed Three-toed Woodpeeker which 1 

 collected in »Siarn 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 occnrs, which is the typical Tiga java- 

 nensis of Ljung. 



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 onty faintly striped, being almost black with onlv a few spöts. Even 

 as far south as at Koh Lak in the Siamese Malaya the long-winged race was found.

Dnring my former journey in Siarn I collected specimens of the Golden-backed 

 Woodpeeker which belonged to the race described by Hesse under the name of Chryso- 

 colaptes guttacristatus iyido-malayicus. This is evidently a southern form which inhabits 

 Siarn north to about Lat. N. 18°. It is merely separated from the northern typical G. g. 

 guttacristatus by its size. 



In the most northern districts, where the collecting was chiefly undertaken during 

 my recent trip, I onlv met with the typical form. Up here TickelPs Golden-backed Wood- 

 peeker was rather rare and onlv a few specimens were observed or obtained. 



South of Lat. N. 18° the southern race was verv common in the open deciduous 

 forests and was certainlv one of the most cbaracteristical birds to that kind of 

 vegetation.
