The form ranges from the Federated Malay States north through 

 the Malay Peninsula to the mountains of Peninsular Burma and 

 western Siam. 



The Raheng male mentioned above is less rufous and Ughter above 

 and the bill seems to be longer when compared with a series of males 

 from Trang. Six males from Trang measure: Wing, 64, 72, 67, 70, 

 72, 68.5; culmen, 18, 19, 18.5, 19, 18, 18.5 mm. The Ptaheng male: 

 Wing, 70; culmen, 20 mm. 



STACHYRIS LEUCOTIS LEUCOTIS (Strickland) 



Timalia leucotis Strickland, Jardine's Contributions to ornithology, p. 63-10, 

 pi. 12, 1848 (Malacca). 



Tvv'o males and one female, Kao Soi Dao, Trang, December 28^ 

 1933, January 1, 1934. 



Dr. Abbott took two males and three females at Kao Soi Dao, 1,000 

 feet, Trang, Peninsular Siam, February 2 and 4, 1899. He gives the 

 soft parts as: Iris dark or blackish brown; upper mandible black, 

 lower mandible leaden; feet fleshy brown with an olive tinge. 



The species ranges from the southern end of the Malay Peninsula 

 as far nortii as Trang; a closely related form, S. I. goodsoni Hartert, 

 occurs in Borneo. 



Owing to the thick heavy bill and heavy feet of this bird, it seems 

 it had better be placed in Thringorhina than in Stachyris, but it is 

 left here lor the present. 



STACHYRIS NIGRICEPS COLTARTI Harington 



Stachyris nigriceps coltarti Harington, Bull. Brit. Orn. Club, vol. 33, p. 61, 1913^ 

 (Margherita, Assam). 



One male and one female, Doi Nangka, November 3 and 16, 1930. 



De Schauensee *^ took a female on Doi Sutep, 4,500 feet, and both 

 Deignan *^ and Chasen and Kloss ^^ have since reported it from there, 

 De Schauensee *^ on his third expedition took two males in the south- 

 ern Shan States and a female at Chiengmai, which he assigns to S. n. 

 davisoni though he thinks they may be intermediate. My two speci- 

 mens from Doi Nangka are certainly not davisoni or dipora, and if not 

 coltarti they must be close to it. I have not had a specimen of the 

 latter to examine, however. 



The form is tawnier than dipora, and the supra-auricular black 

 streak is broader and more pronounced. 



This race ranges from Assam south of the Brahmaputra through 

 western Burma to the mountains of northern Siam.
