BIRDS FROM SIAM AND THE MALAY PENINSULA 349 



M. g. gularis is darker above than connectens, with a more heavily 

 streaked throat.

One male and two females, Yala, Patani, January 30, 1931; two 

 males, Kao Luang, Nakon Sritamarat, October 4, 1930; one male, 

 Singora, June 29, 1929; two males, Koh Samui, August 7, 1931; one 

 male and one female, Pran, southwestern Siam, April 1, 1931 and 

 May 28, 1928 ; two males, Nong Yang, November 16, 1931 ; two females, 

 Hupbon, November 5, 1931 ; one male, Kao Seming, Krat, October 16, 

 1928; one male, Lem Sing, Chantabun, March 16, 1930; one male, 

 Koh Kut, May 22, 1929; one male, one female, and one unsexed, Koh 

 Chang, April 1, 1924, and January 16, 1926; one male, Kao Sabap, 

 October 27, 1933. Dr. Smith collected a set of three eggs at Pran, 

 May 28, 1928, with the parent. 



The two specimens from Pran are not typical but incline to 

 sulphur e a. 



Dr. W. L. Abbott took nine males and three females in Trang, 

 Peninsular Siam, as follows: Prahmon, February 21-22, 1896; Tyching, 

 April 29 and May 27, 1896; Telibon Island, February 25, 28, 1896; 

 near Chong, January 20, 1897; and "Trang", January 4-March 9, 

 1897. He also took the following sets of eggs with nests: Three eggs, 

 Tyching, April 29, 1896; three eggs, Trang, February 14, 1897; three 

 eggs, Trang, March 9, 1897. He gives the soft parts as: Iris dark 

 brown, brownish yellow, greenish or yellow; upper mandible blackish 

 brown or black; lower mandible yellowish olive or dull plumbeous; 

 feet fleshy brown, olive or olive-plumbeous. 



On first sight the Trang series seems to be quite different from 

 specimens to the north and south of it, but I find there is a seasonable 

 change of plumage. The fall and early-winter specimens are a deep 

 yellow, wliich fades badly during the breeding season. The Trang 

 series is in breeding plumage and is much lighter than fall birds to the 

 north and south of it. There are a few breeding birds in Dr. Smith's 

 series and they agree with the Trang specimens. The Koh Kut and 

 Koh Chang birds in Dr. Smith's series do not differ essentially from 

 the Trang series; they are a little more worn and a little more faded. 

 The type of inveterata is in fresh winter plumage and is rather yellow 

 below, but it can be matched by specimens from Peninsular Siam.
