is strongly washed with greenish, the frons and a border to the black 

 throat patch being reed yellow. 



Ten adult males from Siam measure: Wing, 87-9G (92.9); culmen, 

 19.5-20.5 (19.9) mm. Six adult females from Siam: Wing, 82-88 (86); 

 culmen, 18.5-20 (19.3) mm. The wing in these seems to average less 

 than in the measurements given by Stuart Baker ^^ and he does not 

 segregate the se.xes. My measurements show the female to be con- 

 siderably smaller. 



The only female of malayana examined is from the Semangko Pass, 

 Selangor-Pahang boundary. The wing is no smaller (85 mm) than 

 in the Siamese series, but the lesser v/ing coverts are a deeper blue and 

 the primary coverts are washed with blue, while in the northern form 

 there is little or no blue wash. The culmen in this specimen measures 

 17 mm, which is smaller than in northern birds. 



A male in the United States National Museum from near Laichau, 

 Tonkin, more nearly resembles the Indian bird than that from Siam, 

 but the yellow of the pileum is lighter and has more of a greenish wash 

 than the former; wing, 91 mm. 



Chasen and Kloss,^^ in commenting upon a male from Doi Sutep, 

 have likewise noted the intermediate character of the Siamese bird, 

 as has also de Schauensee ^° in writing upon a series from Chiengmai, 

 Khun Tan, Chiengdao, and the southern Shan States, but he believes 

 the northern Siamese bird to be nearer malayana than hardwickii. He 

 apparently did not make a direct comparison with either. It seems 

 best to leave the northern Siamese race with the nominate form for the 

 present. 



C. h. hardwickii ranges from the Himalayas at Simla east to eastern 

 Assam and south through P»urma to the Shan States and Tenasserim 

 and east through northern Siam to Laos, Tonkin, and northern Annum.
