BIRDS FROM SIAM AND THE MALAY PENINSULA 25 



after the rains; Chasen and Kloss ^* record a female from the Raheng 

 District; Gairdner ^^ records it for the Petchaburi District; Robinson 

 and Kloss/^ after recording a male from Pakchan, say that in the 

 south of the Peninsula it is extremely uncommon; Bonhote " records 

 it for Patalung. 



It probably occurs all over Siam in suitable localities. 



The form breeds from India, Ceyion, Burma, and China south of 

 the Yangtze to the Riu Kiu Islands, south to Siam, Indo-China, the 

 Philippines, and the Greater Sunda Islands to Celebes. 



BUTORIDES JAVANICUS ACTOPHILUS Obcrholser 



Butorides javanicus adophilus Oberholser, Smithsonian Misc. Coll., vol. 60, 



no. 7, p. 1, 1912 (North Pagi Island). 

 Butorides javanicus icastopterus Oberholser, ibid., p. 1 (Simalur Island). 

 Butorides siriatus connectens Stresemann, Orn. Monatsb., vol. 38, p. 48, 1930 



(Yaoshan, Kwangsi, China). 

 Butorides javanicus abbotti Oberholser, U. S. Nat. Mus. Bull. 159, p. 14, 1932 



(Pulo Langkawi, western Malay Peninsula). 



One male and one female, Nakon Sritamarat, October 7, 1896, and 

 March 21, 1924; one male, Lem Sing, Chantabun, June 11, 1926; one 

 immature male, Koh Chang, January 5, 1926. 



Dr. W. L. Abbott took an adult and an immature female, Prahmon, 

 Trang, March 7 and 19, 1896; one male, Singapore, May 22, 1899; one 

 male, Domel Island, Mergui Archipelago, February 22, 1900; and a 

 male, Pulo Langkawi, December 4, 1899 (the type of Butorides 

 javanicus abbotti). 



There is an adult male in the United States National Museum taken 

 at Saan Taw, Raheng District, western Siam, April 5. 



The Siamese specimens seem to agree with those from South China 

 in size and color. Oberholser in naming B. j. abbotti included South 

 China within the range of his new race, overlooking the fact that it 

 had been previously provided with a name by Stresemann. Ober- 

 holser gives the range as follows: "India and the Malay Peninsula, 

 north to southern China, Nepal, Kashmir; west to Sind and the 

 Laccadine Islands; south to Ceylon, Sumatra, and Nias; and east to 

 the Natuna Islands and Cochin China." 



After reexamining the types of adophilus and icastopterus, I am 

 convinced that they are only whiter migrants from farther north and 

 differ in no way from specimens from southern China. 



The male from Lem Sing, Chantabun, is small and dark like Javan 

 specimens, and the female from Prahmon, Trang, is also small but 

 not so dark. These two I am regarding as small specimens of the
