(no date), 1896, and February 23, 1899); one male and one female, 

 Tenasserim (10 miles north of Victoria Point, January 5, 1900, and 

 Bok PAnn, February 13, 1900); and one male and one female, Packa 

 Hiver, Trengganu, September 25, 26, 1900. He gives the colors of 

 the soft parts as follows: Bill red, tip black, gape yellow; feet red, 

 claws black; iris dark brown. 



The range of this form extends from Burma and Siam east to Cam- 

 bodia, Cochinchina, Annam, and Laos, and south through Peninsular 

 Siam to Singapore, Java, Borneo, and the Philippines. 



In Siam it apparently is commoner in the southern districts than in 

 the north, as Dr. Smith secured no specimens there, though it is re- 

 ported from that part of the country. All of Dr. Smith's and Dr. 

 Abbott's specimens apparently belong to this form. 



Herbert's collector took a set of three eggs at Ajmthia, April 12,^^ 

 and another set of two eggs at the same place two weeks later. 



EURYSTOMUS ORIENTAUS CALONYX Sharpe 



Eurystomus calonyx Sharpe, Proc. Zool. Soc. London, 1890, p. 551 (Nepal). 



Typical specimens of this form can easily be distinguished from the 

 resident Siamese race by having the primary coverts and outer 

 secondaries azurite blue instead of black, with little or no blue; the 

 Siamese form is darker above also. 



Eurystomus orientalis calonyx breeds in Korea, Manchuria, north 

 China, and middle China and migrates south in winter to the Sunda 

 Islands and the Malay States. Authentic specimens of this race 

 seem to have been taken but rarely in Siam, where, of course, it ia 

 only a winter visitor. Gyldenstolpe ^^ records it from Pak Koh in the 

 north; Robinson and Kloss ^* have recorded it from Trang in Penin- 

 sular Siam, and they ^^ record a male from Tung Pran, Tukuatung, 

 western Siam, taken February 14. Chasen and Kloss ^^ give it for 

 the Raheng District, and one of their specimens from this collection 

 is now in the United States National Museum. Robinson and 

 Kloss ^^ have also recorded it from the Province of Puket, Peninsular 

 Siam, and Ogilvie-Grant ^^ from Patani.
