 dark brown on inner webs, olive-green on outer webs — both these sets

Distrilndion. This is the bird which 1 liave wronglj- recorded 

 [Journ. N. H. >S. Siam, i, p. 197 (1915)] as Gennus vin^iinu>'. The 

 present subspecies is based on a feni de obtained bj' Gyldenstolpe at 

 Pa Hing, in Northern .Siam, and differs from the true G. ritiaius, 

 which occurs in Java, Sumatra and Malaya, chiefly by its larger size. 

 Robinson records two specimens obtained by Kloss in South-eastern 

 Siam, in which part of the countrj- I have likewise ])rocuifd it. 

 My collection al-io includes specimens from I'ak Jong and Jlualc-lek in 

 Eastern Siam, fi'om Bangkok and Ayuthia in tha Central division of 

 the country', and from Hna Hin and Nong Kae in South-western Siam. 

 It thus appears to lie a widely distributed bird. In inj' specimens the 

 wing ranges from 132-l'lo mm. in length. According to Robinson 

 (op. cit., 1915) the present form of this Woodpecker is ()uite cut 

 off from (he true G. fiitatus, as the species inhabitating the Siamese 

 portion of the Malay Peninsula, from about Trang or Bandon nortii- 

 wards, is the allied but perfectly distinct (1. riridanus. If this is so, 

 G. rittatus eisenhoferi is probably ai)proaching the southern limit of its 

 range at Xong Kae. 



My one Bangkok specimen was shot at Wat Thong Insri, on 

 the bank of the Cliao Pliya river, about .'{ miles due south of Sathoi-n 

 Road, on 20th January 1914.
