and 4, 1926; one female, Lat Bua Kao, August 7, 1929; one female, 

 Hupbon, November 5, 1931; one male and two females, Hin Lap, 

 October 1 and December 10, 1931; one male, Kumpawapi, February 

 17, 1929; one male and one female, Aranya, July 16, 17, 1930; one

In the above series, the males have little or no black on the upper- 

 parts at any season. They are serpentine green above, the pileum 

 more yellowish. Below the yellow is less bright than in A. I. lafresnayei 

 and the tail is yellowish citrine, the outside rec trices sometimes with a 

 little black on the inner web, never all black as in the Malay race; 

 bills a little smaller than the latter. 



Ten males of innotatus measure: Wing, 68-73 (70.4); culmen, 

 19-21.5 (19.7) mm. Ten females: Wing, 66-70 (68.1); culmen, 

 18-20.5 (19.2) mm. 



The present form ranges from Arracan, Burma, through northern 

 Tenasserim to southwestern, central, eastern, and southeastern Siam, 

 French Laos, Tonkin, and northern and central Annam. 



In Cochinchina, southern Cambodia, and southern Annam A. I. 

 xanthotis occurs. It is more yellowish on the back than innotatus, 

 and e\ddently does not reach to northwestern Cambodia as the two 

 specimens taken near the border in southeastern Siam seem to belong 

 to the northern race though somewhat more yellowdsh on the pileum. 



De Schauensee ^^ took a male at Chiengsen, January 9, and remarks 

 that it seems to be a rare bird in northern Siam. This is the only 

 record I have seen from the northern part of the country.
