BIRDS FROM SIAM AND THE MALAY PENINSULA 159 



are wider and more pronounced than in North China specimens. 

 The wing in the male measures 169 mm; in the female, 166 mm. 



TMiether this form breeds in Siam I am unable to say, as very few 

 specimens have been collected, but since it has been found in Laos in 

 the breeding season it would occur probably in northern Siam also. 



De Schauensee ^^ took a female on Cliiengdao, 4,500 feet, January 

 19, and reports it common there at that time.

 July 8, 1900. Dr. Abbott describes the tarsi as fleshy brown, the
