Just how far north the present form ranges in Peninsular Siam is 

 not kno\\Ti at present, but it reaches Ban don. This would give it a 

 range from the southern Malay States north to Bandon. 



Besides the localities represented in Dr. Smith's and Dr. Abbott's 

 collections, it has been recorded by Robinson *^* from Koh Samui; by 

 Robinson and Kloss *^ from Telok Poh and Pulo Panjang; by de 

 Schauensee ** from Nakon Sritamarat. I have not examined spec- 

 imens from so far north in Peninsular Siam, and possibly these refer- 

 ences may represent Y. n. canicapillus or are intermediates. 



BLYTHIPICUS PYRRHOTIS PYRRHOTIS (Hodgson) 



Picus pyrrhotis Hodgson, Journ. Asiat. Soc. Bengal, vol. 6, p. 108, 1837 (Nepal). 



One male, summit of Doi Sutep, December 15, 1928; one immature 

 male. Pang Meton (Doi Nangka), May 4, 1931; one immature male, 

 Khun Tan, 4,000 feet, February 14, 1932; one male, Huey Me Lao, 

 December 24, 1932; one female, Kao Pae Pan Nam, Lomsak, February 

 18, 1934. 



The two immature males difi'er principally from the adult male in 

 being dusky blackish below; they are of about adult size. 



The range of this form is from Nepal to eastern Assam south to 

 eastern Bengal, Burma, Tenasserim, western and northern Siam, 



Gyldenstolpe *^ took it at Doi Par Sakeng; Chasen and Kloss " 

 report it from the Raheng District. De Schauensee *^ collected three 

 specimens at Chiengdao and states that it appears to be rare in 

 northern Siam. 



The male recorded by Chasen and Kloss from the Raheng District 

 is now in the United States National Museum. It is smaller than the 

 two males from northern Siam. Wing, 144; tail, 87; culmen, 42 mm. 

 Two males from northern Siam measure: Wing, 151-157; tail, 82-91; 

 culmen, 46-50 mm. 



A small race, Blythipicus pyrrhotis cameroni Robinson, inhabits the 

 Malay States and may extend into Peninsular Siam. B. p. annamensis 

 Kinnear inhabits the mountains of southern Annan, Cochinchina, 

 Laos, and Tonkin. B. p. sinensis (Rickctt) inhabits southern China, 

 and B. p. hainanus (Grant) is confined to Hainan. All the forms of 

 the species seem to be mountain birds and for this reason are more or 

 less localized.
