 be seen from the following measurements : —

The largest bird in this series is a female with a wing of 

 149 mm. from as far south as Pakjan in peninsular Siam, 

 whereas there is another female from as far north as 

 Bangkok with a wing of 1.28 mm., smaller than any of the 

 Javan males. 



I can only distinguish two races of this Woodpecker : — 



f- (1) Picus vittatus vittatus. 



Picas villalus Vieill. Nouv. Diet. d'Hist. Nat. xxvi. 1818, 

 p. 91 : no locality. 



Picus villalus eisenhoferi Gyldenstolpe, Orn. Monatsb. 

 xxiv. 1916, p. 28 : Pa Hing, N. Siam. 



Type locality. Malacca. 



Habitat. Java, Malay States, western and eastern penin- 

 sular Siam and Burma, and thence into south-eastern Siam 

 as far as Bangkok, and thence again, if Gyldenstolpe is 

 correct as referring his birds as nearest vittatus, and not 

 viridanus, well up into north central Siam, also Cochin 

 China. The exact range of villalus and viridanus evidently 

 wants more careful working out unless eisenhoferi is viri- 

 danus. 



'^{2) Picus vittatus viridanus. 



Ficus viridanus Blyth, J. A. S. B. xii. 1843, p. 1000. 



Gecinus weberi Miiller, Journ. f. Orn. 1882, p. 421 : 

 Salauga. 



Type locality. Arrakan. 



Differs from P. villains villalus in having the whole of 

 the underparts streaked from vent to upper breast.
