 one male, Doi Bata, December 25, 1932; one male, Mae Hong Som, 

 January 7, 1933; one male, Muek Lek, April 26, 1933. 



Gyldenstolpe ^* reports this falconet rather common in northern 

 and northwestern Siam and apparently rarer in eastern Siam; 

 Deignan ^^ reports it common on Doi Sutep to 3,000 feet, more rarely 

 to 5,500 feet, and "widely distributed on the plain at Chiengmai in 

 winter; Chasen and Kloss ^® report it from the Raheng District, 

 western Siam ; de Schauensee " saw several birds entering holes at 

 Chiengdao, January 8 ; three were shot and they were all adult females. 



Three of the females reported upon by Chasen and Kloss from the 

 Raheng District are in the United States National Museum. One 

 of the females has the forehead, superciharies, and a small patch 

 below the eye rufous; the throat is pure white; an immature plumage. 

 The form is not uncommon evidently over all Siam proper. It ranges 

 from Burma and the Shan States south to northern Tenasserim, Siam, 

 and Indo-Cliina. 



NEOmERAX INSIGNIS CINEREICEPS (Baker)

 p. 101, 1927 (Myawadi, Tenasserim). 



Two females, Doi Angka, December 2, 1928. 



Gyldenstolpe ^^ reports this hawk taken in northern, southeastern, 

 and eastern Siam; Chasen and Kloss ^^ report it from Raheng Dis- 

 trict, western Siam; Deignan^*' states that it is uncommon on the 

 lowest slopes of Doi Sutep from October to January and common 

 at all seasons in the barrens near Chawmtawng, to the south of 

 Chiengmai ; Lowe ^^ found a pair nesting 58 miles east of Umpang, 

 February 17. 



The United States National Museum received a pair of these hawks 

 from the Raffles Museum from the Raheng collection reported upon 

 by Chasen and Kloss. The female is in very worn plumage; the male 

 is a bird of the year, with the nesoptiles still adhering to the feathers 

 of the back. The male has a white collar and the lower parts pure 

 white with no streaks at all, even on the flanks. This does not agree 

 with Baker's ^^ description of the immature of the species. 



The two females from Doi Angka are verj^ dark gray above, tbe 

 head and hindneck russet with fine blackish shaft streaks. The
