Specimens of this Woodpecker vary to a very great degree 

 intei- se from all parts of the range. Thus tliree birds from 

 Tounghoo are so different from one another that they might 

 well be taken for three geogfaphical races, if not for distinct 

 species. One bird has the back bright grass-green, a second 

 has it dull dark green, whilst the third has the whole of 

 these parts covered with a bright bronze-yellow sheen. 



In size they do not vary greatly, though, as usual, northern 

 birds average a trifle larger than southern. But even in tliis 

 respect the individual variation is so great throughout the 

 range, that it does not seem advisable to attempt any division 

 into geographical races on the ground of variation in 

 measurements. 



The birds obtained by Mr, Herbert appear to be the tirst 

 actual record of its appearance iu Siam, as all the birds from 

 this country labelled viridanus in the British Museum are 

 true v'ltlatas. 



Habitat. Burma, Chin Hills, Kachin Hills, southern Shan 

 States, "north and central Siam, and possibly the extreme 

 west of peninsular Siam and Burma. P. v. vittatus appears 

 to work up the eastern side of the peninsula into Siam and 

 Cochin China. 



The form found in the island of Salanga [S. iveberi) is 

 also nothing but viridanus. 



J^ PICUS ERYTHROPYGIUS, 



As at present accepted, there are two races of this 

 Woodpecker, P. e. erytkropygius from Cochin China, and 

 P. e. nigrigenis from Burma, etc. 



The only two birds of the former race which I have been 

 able to examine are the type, a female in the British Museum 

 collection, and a male in Lord Rothschild's Tring Museum. 

 Mr. Kloss has, however, recently ascribed to this subspecies 

 certain specimens obtained in Siam, and three specimens 

 ol)tained by Mr. E. G. Herbert from the same country on 

 the whole support his view. Mr. Kloss is not, however, 

 quite accurate in referring to nigriyenis as " a very distinct 

 subspecies and a far handsomer bird," for the difference
