514 BULLETIN 17 2, UNITED STATES NATIONAL MUSEUM 



Ten males from the Malay Peninsula, from the Malay States to 

 Trang, measure: Wing, 46-50.3 (48.7); tail, 22.5-26.5 (24); culmen, 

 10-11 (10.3) mm. Eight males from east and southeast Siam: 

 Wing, 45-49 (47); tail, 23-26 (24.2); culmen, 9.5-10.5 (10.2) mm. 

 Eight males from northern Siam: Wing, 46-50 (47.9); tail, 23-27.5 

 (24.6); culmen, 10-11 (10.6) mm. 



There are two immature specimens in the series taken at Bangkok, 

 a male taken May 9 and a female taken May 4. They resemble the 

 adult female except the upper and lower parts are tinged ohve-green, 

 the red of the rump is reduced, and the base of the bill is light colored. 

 The female is the younger of the two and more ohve-green. 



Just what the exact range of this form is 1 am not certain. It evi- 

 dently ranges from the Malay States north through Peninsular Siam 

 to Tenasserim, Burma, and all Siam proper and east into Cambodia, 

 Cochinchina, Laos, Tonkin, and Annam.

One male and one female, Khun Tan, 4,000 feet, February 22, 1932; 

 one female, Mae Hong Som, January 5, 1933; one male, Khun Tan 

 Mountains, 4.000 feet. May 9, 1933; two females, Doi Hua Mot, 

 August 21, 1934. 



Dr. W. L. Abbott took a male and a female on Kao Nom Plu, 

 3,000 feet, Trang, February 22, 26, 1897; and a male labeled simply 

 Trang, January 20, 1899. 



The United States National Museum possesses a good series of 

 this species from western and southern China but only one male from 

 the rest of its range outside of Siam. The Chinese specimens do not 

 differ materially from those of Siam. The one male referred to above 

 is from the Langbian Peaks, southern Annam. It is a bluish green 

 above, while the Siamese males are a coppery green, but I think this 

 an age difference rather than a geograpliic. In the Chinese series 

 mentioned above there are two immature males that have almost 

 assumed the adult plumage and the back is coming in a shining 

 coppery green while in an adult male (no. 306396), Mount Omei, 

 July 9, the upperparts are bluish green like those of the South Annam 

 male. It is possible that only the very old males assume this bluish 

 green plumage, as in an extensive series the above are the only speci- 

 mens in this plumage. 



This bird has been reduced to the rank of a form of Dlcaeum 

 sanguinolentum of Java by some recent authors, but the latter is quite 

 distinct. The back is a glossy purple instead of coppery and there 

 are other differences.
