This Woodpecker, which is common in Burma and Tenas- 

 serim and in many parts of the Malay Peninsula, south to

Tickell's type came from somewhere in north Tenasserim 

 about the centre of the range of the species, which extends 

 from the Sikkira Himalayas to the south of the Malay 

 Peninsula. As is repeatedly the case in this region, northern 

 birds are larger and duller and southern birds smaller and 

 brighter, and both have received names, viz., C. sultaneus 

 (Gould) for birds from Assam and C. indo-malayicus for 

 birds from north Malay Peninsula. The case is a curious 

 one of interest to trinomiaiists. Most modern ornithologists 

 would admit that valid subspecific differences exist between 

 the extremes C. sultaneus from the north and C. indo-mala- 

 yicus from the south-east. Owing to the f\ict that a median
