One female, Nakon Patom, April 10, 1926; two adult males, one 

 adult female, and one immature female, Bangkok, March 14 and 

 June 27, 1924, October 23, 1925, November 4, 1926; two males, Rang- 

 sit, May 5, 1929; one male, Nongkae, May 5, 1929; two males, one 

 female, and two young. Bung Borapet, June 21, 28, 1932. 



The two young taken at Bung Borapet, June 21 and 28, are con- 

 siderably smaller than the adults. In the younger of the two speci- 

 mens the pileum is buffy white, the crown and nape with dusk}^ cross 

 bars; a black masque embracing the subocular and auricular region; 

 hindneck gray, barred \vith fuscous; remainder of upper parts ochra- 

 ceous-butf barred with fuscous but with some russet feathers of the 

 next plumage coming in; a new blackish tail is replacing a tawny one; 

 the inner remiges are bordered with tawny; the lower parts are wliite, 

 band across chest and sides warm buff with sparse very fine cross, 

 bars; under tail coverts warm buff. 



The immature taken at the same place, June 21, is similar, but the 

 cross bars on the head come farther forward, and a few black featherS: 

 are appearing on the nape. 



An immature female taken at Bangkok, June 27, is similar to the 

 last, but it has a longer and browner tail, the bars on the head are^ 

 heavier and come farther forward. It is a larger and older bird.
