BIRDS FROM SIAM AND THE MALAY PENINSULA 465 



TERPSIPHONE AFFINIS AFFINIS (Blyth) 



Tchitrea affinis Blyth, Journ. Asiat. Soc. Bengal, vol. 15, p. 292, 1846 (Malay 

 Peninsula, Tenasserim, and Arrakan; type locality as restricted by Salo- 

 monsen,'^ Malacca). 



Dr. W. L. Abbott collected the following: One male, the Bindings, 

 Straits of Malacca, April 13, 1900; one male, Endau River, Pahang, 

 June 27, 1901; one m.ale, Rimipin River, Pahang, May 24, 1902, and 

 one immature, not sexed, Packa, Trengganu, September 27, 1900. 



The two males from Pahang are in the red plumage. They are 

 much darker above and below than indochinensis in the same plumage, 

 and the throats are washed with a sliining bluish black ; the under tail 

 coverts also are darker. No specimens approach them from Patani 

 or farther north. If these differences hold in a larger series, the 

 northern form (indochinensis) should certainly be recognized. 



The three males measure: Wing, 90-99 (93.3); outer tail feather, 

 75.5-87 (79.5); culmen, 20-21 (20.7) mm. 



The form range is confined to the Malay States; possibly it may 

 reach the southern part of Patani,

TERPSIPHONE AFFINIS INDOCHINENSIS (Salomonsen) 



Tchitrea affinis indochinensis Salomonsen, Ibis, 1933, p. 734 (Angkor, Cambodia). 



Four males and one female, Bangnara, Patani, May 11 and 17, 1924, 

 July 7-9, 1926; one male and two females, Kao Luang, Nakon Srita- 

 marat, July 16-19, 1928; one male, Huey Yang, Kao I^uang, October 5, 

 1930; three males, Sichol, Bandon, May 15-27, 1930; one male, Pak 

 Chong, December 9, 1929; one male, Koh Chang, January 16, 1926; 

 five males and two females, Kao Sabap, Chantabun, January 7-9, 

 1930, November 1-25, 1933; one male, Kao Seming, Krat, October 12, 

 1928. Dr. Smith also took a male in the white plumage at Vientiane, 

 Laos, February 21, 1929. 



Dr. W. L. Abbott collected nine males and one female in Trang 

 (Trang, February 3-13, 1897, January 25, and March 3, 1899, Kao 

 Soi Dao, February 2-20-1899); one male, Domel Island, Mergui 

 Archipelago, January 22, 1904. 



Out of the considerable series of this form taken in Siam by Drs. 

 Abbott and Smith, tliere are 10 males in the white plumage. This is 

 a minority of the series, but the reason for this is probably that it 

 takes two or more years to attain this plumage and specimens naturally 

 would not be so numerous. I have handled specimens of T. paradisi 

 that were changing from the red to the white plumage, and undoubt-
