1933; four males and one female, Khun Tan, 3,000 feet, October 18 

 and 21, 1929, August 28, 1930, February 20-22, 1932; one female, 

 Kao Pae Pan Nam (west of Lomkao), February 18, 1934; one male and 

 two females, Doi Hua Mot, August 23-September 1, 1934. 



This form ranges from Nepal to eastern Assam, the whole of Burma 

 to Tenasserim and northern Siam. In the mountains of the Malay 

 States a smaller darker race is found. In Siam it has been found as 

 far south as the Raheng District, according to Barton ^^. 



De Schauensee ^* took a good series at Chiengmai and Chiengdao 

 and makes some interesting technical remarks on the relationship of 

 several of the forms to which I quite agree. 



HARPACTES EUYTHROCEPHALUS KLOSSI (Robinson) 



Pyrotrogon eryihrocephalus klossi Robinson, Ibis, 1915, p. 735 (Koh Chang, south- 

 eastern Siam). 



Two males and two females, Koh Chang, January 5, 1925, January 

 9-11, 1926; one male and one female, Kao Kuap, Krat, December 24 

 and 26, 1929; one male, Kao Lem, December 27, 1930; one male and 

 two females, Kao Sabap, October 28-November 26, 1933. 



The male from Kao Lem differs from the remainder of the series in 

 having the throat and chest darker red, the white bars on the wing 

 coverts are wider, and the back darker brown. I am placing it with 

 klossi for the present, however. 



This is a smaller form than the northern Siamese race of this species, 

 and the white bars on the wing coverts are narrow^er. From the small 

 form inhabiting the Malay States (chaseni) it differs in being not so 

 dark above and in being brighter red below, especially on the throat 

 and chest. 



H. e. klossi ranges from southeastern Siam into Cambodia. Very 

 little is known of its distribution. 



There are several other described races of H. eryihrocephalus, includ- 

 ing the following: 



Harpades eryihrocephalus yamakanensis Rickett (Fukien and Kwangtung 



Provinces, China). 

 Harpades eryihrocephalus rosa (Stresemann) (Kwangsi, China). 

 Harpades eryihrocephalus hainanus Grant (Hainan). 

 Harpades eryihrocephalus inlermedius Kinnear (Tonkin, North Annam, 



and Laos). 

 Harpades eryihrocephalus annamensis (Robinson and Kloss) (southern 



Annam, southern Laos, and Cochiiichina). 

 Harpades eryihrocephalus flagrans (Miiller) (Sumatra and ? Borneo). 

 Harpades eryihrocephalus chaseni Riley (mountains of the Malay States). 



As the species is a mountain-inhabiting one and apparently does not 

 occur in the lowlands, the various forms are more or less isolated.
