DRYMOCATAPHUS TICKELLI TICKELLI (Blyth) 



Pellorneum tickelli Blyth, Journ. Asiat. Soc. Bengal, vol. 28, p. 414, 1859 (Am- 

 herst, Tenasserim). 



The United States National Museum contains the female of this 

 form from Hue Nya Pla, Raheng, 2,500 feet, May 20, 1924, ^^ recorded 

 by Chasen and Kloss. 



Robinson and Kloss ^* report it from Renong River, Tapli (Pak- 

 chan), and Tasan (Chumporn), all in Peninsular Siam. The form is 

 said to extend from Assam south of the Brahmaputra, and south to 

 southern Tenasserim and for a short distance farther south into 

 Peninsular Siam; eastward it extends to western Siam (Raheng). 



DRYMOCATAPHUS TICKELLI OLIVACEUS Kinnear 



Drymocataphus tickelli olivaceus Kinneak, Bull. Brit. Orn. Club, vol. 45, p. 11, 

 1924 (Bao Ha, Tonkin). 



Three females, Khun Tan, 3,000 feet, October 27, 1929, and Feb- 

 ruary 24 and 26, 1932; one female, Kao Pae Pan Nam, Lamsak, 

 February 18, 1934. 



The above specimens from Khun Tan are more olive-brown, much 

 lighter than either tickelli or australis; below they are lighter, less 

 buffy, the chin and throat white like the center of the breast. In 

 tickelli and australis the chin is buffy like sides of neck. I have had 

 no specimens of olivaceus for comparison, but when placed beside 

 tickelli and australis, the Khun Tan birds stand out as quite distinct, 

 and if they are not this form they require a name. 



The female from Kao Pae Pan Nam is darker above than the Khun 

 Tan specimens but is nearer to this form than to the other two ac- 

 credited to Siam. 



Count Gyldenstolpc's record of D. t. tickelli ^^ from Pak Koh 

 probably belongs here; Deignan ^^ took a female on Doi Angka, 4,400 

 feet, April 19, 1931; de Schauensee ^^ obtained a male at Chiengdao, 

 4,000 feet. 



The form evidently ranges from northern and eastern Siam to Laos, 

 Tonkin, and northern Annam.
