deeper yellow below; there is no dark line on the side of the neck; 

 and the lores are whitish or grayish. 



The two males of G. m. pecioralis measure: Wing, 49-50; tail, 32-33; 

 culmen, 10-10.5 mm. The three females of 6. m. pectoralis: Wing, 

 46.5-48.5 (47.3); tail, 30-34 (31.3); culmen, 9.5-10 (9.7) mm. The 

 single female of G. m. modiglianii: Wing, 49; tail, 33; culmen, 10.5 mm. 



Robinson and Kloss *^ mention a specimen from Pulo Panjang 

 Amak, a small island near Junkseylon, and make some critical remarks; 

 later they ^* received a series from Koh Lak and make some additional 

 remarks on the status of the form. 



Whether G. m. pectoralis is really distinct from G. m. modiglianii 

 it is impossible to say with the series at my command, but I consider 

 its wiser to recognize it until a larger series can be examined from 

 Sumatra. 



G. m. pectoralis would then range from the Malay States north 

 through Peninsular Siam to southwestern Siam. 



XANTHOPYGIA ZANTHOPYGIA (A. Hay) 



Muscicapa zanthopygia A. Hay, Madras Journ. Lit. and Sci., vol. 13, pt. 2, p. 162, 

 1844 (1845) (Malacca). 



One female, Koh Lak, September 23, 1928; two males, Pran, 

 April 1, 4, 1931; one male, Tha Lo, Bandon, September 24, 1931; 

 one immature male and two females, Bangkok, April 10, 13, 1934. 



This species breeds from Sakhahn Island, Korea, Manchuria, 

 eastern China, and as far south as the Yangt; e and west to Szechwan 

 and migrates through southern China and Indo-China to winter in 

 Peninsular Siam and the Malay States. 



The only records known to me for Siam, outside the Peninsular 

 and the southwestern sections, are the one of Kloss ** for Lat Bua Kao, 

 in the eastern district, and the one of Deignan ®^ of a male taken at 

 Ban Nako, Nan, April 2, 1936. 



The United States National Museum contains a good series of breed- 

 ing birds of this species from Korea and China. The Korean birds 

 are paler yellow below. Both styles are represented in the three 

 males taken by Dr. Smith ; the two from Pran are like those of China, 

 while the one taken at Tha Lo is Hke the breeding bird from Korea.
