BIRDS FROM SIAM AND THE MALAY PENINSULA 507 



ARACHNOTHERA CHRYSOGENYS COPHA Oberholser 



Arachnothera chrysogenys copha Oberholsek, Smithsonian Misc. Coll., vol. 60, 

 no. 7, p. 20, 1912 (Tapanuli Bay, northwestern Sumatra). 



Arachnothera chrysogenys aslilpna Oberholser, Journ. Washington Acad. Sci., 

 vol. 13, p. 227, 1923 (Bok Pyin, Tenasserim). 



Arachnothera chrysogenys intensiflava Baker, Bull. Brit. Orn. Club, vol. 46 p. 14, 

 1925 (Kossoom, Tenasserim). 



Dr. W. L. Abbott took one male and one female in Trang, February 

 24, 1899; and three males at Bok Pyin, Tenasserim, February 14, 17, 

 1900. He gives the soft parts as: Iris brown; bill dark horn brown; 

 a narrow yellow line along the commissure; feet fleshy, claws dark 

 horn brown. 



This small series does not appear to differ from a larger series from 

 Sumatra. A small series from the Katem.an River, eastern Sumatra, 

 differs somewhat from three males from the type locality. They 

 appear to be more yellowish above and below. They were taken in 

 September, and I attribute the differences to season. 



Three males from Trang (1) and Tenasserim (2) measure: Wing, 

 82.5-87 (84.2); tail, 35.5-40 (38.2); culmen, 37.5-40.5 (39.2) mm. 

 Five males from Sumatra: Wing, 82-89.5 (85.9); tail, 35.5-38.5 (37.4); 

 culmen, 36-38.5 (37.4) mm. 



The form ranges from Tenasserim south through Peninsular Siam 

 to the Malay States and Sumatra, 



Ogilvie-Grant *^ records it from Patani; Robinson and Kloss ^^ from 

 Trang; Robinson ^° from Kao Nawng, 1,200 feet, Bandon; Robinson 

 and Kloss *^ from Tapli; de Schauensee ^'^ from Nakon Sritamarat. 



ARACHNOTHERA MAGNA MAGNA (Hodgson) 



Cinnyris magna Hodgson, Indian Rev., vol. 1, p. 272, 1836 (Nepal). 



One male, Khun Tan, September 9, 1930; one male, Doi Nangka, 

 November 20, 1930; one female, Pang Meton (Doi Nangka), May 4, 

 1931; two males, Doi Hua Mot, August 19-21, 1924. 



These specimens have been compared with an unsexed specimen 

 from Nepal and a male from Tenasserim. The Nepal bird is probably 

 a female; allowing for this, the northern Siam birds seem to me to 

 agree with it better than they do with the Tenasserim male. The 

 four males from Siam are a little larger, measuring: Wing, 92-94 (93); 

 culmen, 42-45 (43.8) mm. One male from Tenasserim measures: 

 Wing, 90; culmen, 40 mm. A male from the Selangor-Pahang bound- 

 ary is as large as the northern Siam specimens: Wing, 93; culmen, 

 44 mm. It is less heavily streaked above, however, and in this respect
