 " Iris chocolate, upper mandible black, lower yellow, 

 slate at tip, feet olive, orbits slate." 



Both bronzy green and olive green types are represented 

 in the series from each island, all the specimens being quite 

 adult. 



Two males from Koh Muk present a curious abnormality, 

 having the feathers of the flanks and abdomen largely creamy 

 white, evidently due to partial albinism, which is by no means 

 uncommon among species both of birds and mammals inhabit- 

 ing small islands in the Malayan ;irea, and presumably to be 

 explained by deterioration of stock due to excessive inbreeding. 



In the north of the Peninsula, this species takes the place 

 of G. vittatus, which has not been met with north of Langkawi, 

 while the southernmost specimen of G. viridanus in our poss- 

 ession was obtained at Pelarit, Pedis. The relation between 

 the two forms is however evidently not subspecific as the large 

 series in the Museums show no evidence of intergradation.

Gyldenstolpe (loc. cit.) is probably not incorrect in separ- 

 ating the northern race of this woodpecker from that inhabit- 

 ing the Southern Malay Peninsula, Java and Sumatra, though 

 the material at his disposal appears to have consisted of a 

 single female with a wing of 142 and a tail of 128. 



The present bird has the wing 137 and the tail, which is 

 not completely grown, about 114. TwoQther females from the
