BIRDS FROM SIAM AND THE MALAY PENINSULA 213 



The species ranges from Burma, except the extreme northwestern 

 part, south to Tenasserim, western, southwestern, and Peninsular 

 Siam as far as Patani. Lowe ^ reports it from 28 mOes east of Um 

 Pang, Siam, which is about as far north as I have seen any records. 

 It is evidently common or fairly so in Peninsular Siam, where it has 

 been taken as far south as Patani.^ 



The species can be easily distinguished from Picus vittatus by the 

 streaked foreneck and chest and from Picus myrmecophoneus by the 

 larger size, darker coloration below, and blackish upper mandible. 



PICUS MYRMECOPHONEUS MYRMECOPHONEUS Stresemann 



Picus myrmecophoneus Stresemann, Verh. Orn. Ges. Bayern, vol. 14, p. 289, 1920 



(new name for Picus striolatus Blyth, 1844; Himalayas). 

 Picus xanthopygius Oberholser, Proc. Biol. Soc. Washington, vol. 32, p. 8, 1919 



(not of Bonaparte, 1850). 



One male. Bo Ploi, Kanburi, September 8, 1928. 



This woodpecker is easily distinguished from Picus vittatus forms 

 by having the foreneck and chest streaked and from P. viridanus by its 

 much lighter underparts and the different pattern of the feathers of 

 these parts. In viridanus the feathers of the breast have the shafts 

 wliitish, then a broad band of fuscous, then a narrow subterminal 

 band of pale yellow. In P. m. myrmecophoneus the feathers of the 

 breast have the shafts blackish, then a broad band of light yellow, and 

 a subterminal band of blackish, P. m. myrmecophoneus is much 

 smaller than P. viridanus or P. vittatus eisenhoferi. 



The specimen collected by Dr. Smith is subadult but differs from 

 the adult only in minor details. The red of the head is confined to the 

 forehead, with only a few scattering red feathers in the crown and 

 nape and the upper mandible is black instead of horny brown. 



The range of this form extends from Ceylon and Peninsular India 

 to the Himalayas, eastern Assam, Cliin Hills, Burma, Siam, Cochin- 

 china, and Cambodia. This seems to be more or less of a rare wood- 

 pecker in Siam. Gyldenstolpe ^ records it from northern Siam ; Chasen 

 and Kloss * as Picus viridanus, later corrected to Picus myrmecopho- 

 neus,'^ from the Raheng District. Kloss ^° took an adult male at Koh 

 Lak, the most southern specimen known to me. It was later acquired 

 by the United States National Museum. De Schauensee " took a 

 male at Tamuang recorded as Picus xanthopygius. 



A larger race, Picus myrmecophoneus dehrae Baker, inliabits Kumaon, 

 Garhwal, Nepal, and upper Pegu.
