agrees with the Tenasserim male. Two females from southern Annam 

 are more greenish yellow above and I believe belong to another race. 

 As a matter of fact, my series is not adequate for me to make any 

 definite decision, and under the circumstances I believe it is better to 

 place the northern Siamese specimens under A. magna magna rather 

 than under A. m. aurata. 



Just what the range of this form is I do not know, but probably: 

 Himalayas from Nepal to Assam, northern Burma, and northern Siam. 



Gyldenstolpe ^^ secured it at Bang Hue Hom, northern Siam, and 

 observed it in eastern Siam. On his second expedition ^* he took it at 

 Chienghai, Khun Tan, and Doi Par Sakeng. De Schauensee ^^ on 

 his third expedition secured a series at Chiengdao and Chiengmai 

 and says that curiously enough on Doi Sutep none were seen until 

 February 28 and that during summer it apparently became com.mon. 

 Lowe ^^ records it from 28 miles east of Umpang.

 vol. 13, p. 226, 1923 (Loh Sidoh Bay, northwestern Sumatra). 



Two males and two females, Bukit, Patani, January 25, 1931; 

 one male, Kao Luang, Nakon Sritamarat, July 14, 1928; one male, 

 Tha Lo, Bandon, September 17, 1931; two immature males, Sichol, 

 Bandon, May 17, 1930. 



Dr. W. L. Abbott collected four males and three males in Trang 

 (Lay Song Hong, December 14, 1896; Chong, January 24, 1897; 

 Trang, February 4-5, 1897, and January 28, 1899); two females, 

 Endau River, east coast of Johore, July 1, 18, 1901; and one male, 

 Boyces Point, Tenasserim. He gives the colors of the soft part as: 

 Iris brown; bill brownish black above, pale brown beneath; feet pale 

 brownish fleshy, claws pale horn brown. 



There seems to be little or no difference in color between Malay 

 Peninsula specimens and those from Sumatra. A larger series of the 

 latter possibly might show some difl'erence in size. 



Seven males from Peninsular Siam measure: Wing, 81.5-86 (83); 

 tail, 44-52 (47.7); culmen, 35-40 (37.6) mm. Three males from 

 Sumatra: Wing, 81-83 (82.3); tail, 46-50 (47.3); culmen, 33-35 (34). 

 The females are considerably smaller than the males. Seven females 

 from Peninsular Siam (5) and Johore (2) measure: Wing, 70-77.5 

 (73.4); tail, 39.5-46 (42); culmen, 33-35.5 (34) mm. Three females 

 from Sumatra: Wing, 72-75 (73.2); tail, 39-42 (40.8) : culmen, 31-32.5 

 (31.7) mm.
