BIRDS FROM SIAM AND THE MALAY PENINSULA 59 



female from Ralieng is similar in the color of the back, but the color 

 of the head is lighter. It is somewhat faded, as the bird is in very- 

 worn plumage. These northern and western records may belong to 

 Neohierax insignis insignis. 



N. i. cinereiceps is resident from Tenasserim to Siam and Indo- 

 China. 



FALCO SEVERUS SEVERUS Horsfield 



Falco severus Horsfield, Trans. Limi. Soc. London, vol. 13, p. 135, 1821 (Java). 



One adult male, Pran, April 1, 1931. 



The only specimens with wliich I have been able to compare the 

 above specimen are two males and a female from the Philippines and 

 a male from Cochinchina. The latter is immature and may be dis- 

 regarded. The Pliilippine specimens are darker above and below 

 than the Siamese male, and in all three of the Pliilippine birds the 

 throats are washed with orange-cinnamon, while in the Siamese bird 

 tliis region is pure wliite. There is Uttle or no difference in size, 

 however. 



Gyldenstolpe ^^ says that this falcon is extremely rare in Siam and 

 hitherto recorded only from Bangkok and Koh Lak ; Deignan "* found 

 it on Doi Sutep at 1,800 feet in June; de Schauensee ^' took a pair at 

 Nakon Nayok, November 17, and a male at Chiengmai, December 23. 

 There are apparently no records, however, for Peninsular Siam, where 

 it will eventually be found. It has a rather wide range, occurring 

 from Assam, Tenasserim, and Siam to Indo-China, Java, and the 

 Philippines. 



CERCHNEIS TINNUNCULUS SATURATUS (Blyth) 



Tinnunculus saturatus Blyth, Journ. Asiat. Soc. Bengal, vol. 28, p. 277, 1859 

 (Tenasserim) . 



Two females, Bangkok, December 17 and February 19, 1923. 



The February specimen is lighter than the December one, but it is 

 more worn and faded. 



Dr. W. L. Abbott took an adult female at Kantany, Trang, January 

 17, 1897. 



This race is a winter visitor to Siam, where it has been recorded 

 from Trang, Langkawi, and Koh Lak ; Deignan ^^ says that this bird 

 is uncommon at Chiengmai from October to February, ascending the 

 mountain (Doi Sutep) to 3,500 feet. It breeds from Yunnan and 

 the hills of eastern and central Burma to Tenasserim." 



It may eventually be found breeding in northern Siam.
