 tlie white spöts are only confined to tlie basal part of the feathers; målar stripe black

During one of my excursions to a fairly dense evergreen forest at the neighbour- 

 hood of Pa Hing I came across a pair of these Woodpeckcrs and I succeeded in shooting the 

 female. Pa Hing is a small hamlet situated in the middle of a large forest on about Lat. 

 N. 18° 10'. The typical Picus vittatus Vieill. is a southern form and the occurrence of 

 a subspecific race of that species as far north as to Lat. N. 18° adds a considerable distance 

 to its geographical distribution to the north. Like many other birds the northern forms 

 are always growing larger than the southern ones.

Iii the parts of the Siamese Malaya visited during my jonrney the Burmese Scaly- 

 bellied Woodpecker was rather common. It never seems to ascend the higher hills and 

 was most of ten met with in open jungles near the sea-shore, sometimes in company with 

 Langhing Thrushes (Garrulax leucolopfius diardi Less.). 



To the north it has been found as far as Bangkok and its neigbourhood bnt north 

 of that place I never found it. 



My specimens perfectly well agree with the descriptions in the literature but both 

 the specimens have much longer wings and tails than recorded. The female specimen in 

 my collection has one of the tail-feathers quite white with a whitish shaft. 



It inhabits the Malay Peninsula as far south as the Patani States and Kedah but 

 further south its place is taken by the typical race of the allied Picus vittatus Vieill.

Similar to Picus canus occipitalis Vig. from Northern India but distinguished 

 by a smaller size. The general colouration is also much brighter than in that species.
