BIRDS FROM SIAM AND THE MALAY PENINSULA 249 



The name Corydon sumatranus (Raffles) ^^ is evidently to be used for 

 the species. Eurylaimus corydon Temminck ^^ is a nomen nudum 

 where first used and was not properly used until about two years later/* 

 while in the meanwhile Raffles had named it. 



A dark-throated form from Borneo similar to that of Sumatra has 

 been named C. s. brunnescens by Hartert. C. s. sumatranus (Raffles) 

 is confined to Sumatra.

Three males and three females, Bangnara, Patani, May 30, 1924,

 females, Bandon, January 7, 1927; two males and four females, Tha Lo, 

 Bandon, September 13-16, 1931; two females, Pran, May 26, 1928; 

 April 2, 1931 ; two males, three females, and one unsexed, Muang Kan- 

 buri, April 9-11, 1928; three males and three females, Nong Khor, near 

 Sriracha, September 23, 1925, February 12, 1927 ; one female. Ban Tarn 

 Dam, near Sriracha, March 6, 1930; one male and one female, Sakeo, 

 near Krabin, May 3, 1928; four males and one female, Kao Seming, 

 Krat, October 10-15, 1928, August 27, 1931 ; one set of four eggs. Ban 

 Sadet, May 25, 1925. Dr. Smith describes the soft parts as: Iris 

 green; bill greenish blue; legs blue. 



Dr. W. L. Abbott collected the following: Two males and six 

 females, Trang (Tyching, May 29-July 3, 1896; Lay Song Hong, 

 September 30, 1896; Chong, January 21, 1897; near Kao Nok Ram, 

 January 4, 1899); one male, Packa, Trengganu, September 27, 1900, 

 and one female, Bok Pyin, Tenassermi, Februarj^ 11, 1900. He also 

 took three sets of three eggs each in Trang, May 29, 30 and June 19, 

 1896; all with incubation begun. He describes the soft parts as: Bill 

 pale blue, the lower mandible orange, except along the commissure; 

 feet leaden blue, soles brownish yellow; iris emerald-green. 



Two of the specimens collected by Dr. Abbott in Trang and the one 

 from Tenasserim have the under tail coverts ochraceous-tawny, and 

 two others from Trang and the one from Trengganu are similar but 

 have a garnet-broMn wash. Strange to say, none in the large series 

 collected by Dr. Smith matches them; they have the under tail coverts 

 red like the breast. As all the birds from Trang do not possess this 

 character, I conclude it is an individual variation. As Robinson and 

 Kloss ^° have remarked, there is a progressive increase in the amount
