b. juv. Muangla, Sanda Valley, Yunnan, May 1868. 



The sex of this adult female (PL XL VI) was accurately ascertained, and I take 

 the opportunity to figure alongside of it the young specimen shot at Muangla ; also 

 the male hird (PL XLV). 



I ohserved this hird only at Tsitkaw and at Muangla. In the former locality 

 it was ohserved hunting over the level marshy expanse behind the village, and at 

 Muangla, over the rice-fields between the hills and the Taho river.
