BIRDS FROM SIAM AND THE MALAY PENINSULA 429 



The Peninsular specimens are slightly darker above than those from 

 eastern Siam, but the difference is very slight. There seems to be no 

 difference in size. Nine males from northern and eastern Siam 

 measure: Wing, 42-45.5 (43); tail, 39-51 (41.8); culmen, 12-12.5 

 (12.2) mm. Four m.ales from Peninsular Siam: Wing, 40.5-44 (42.5); 

 tail, 41-45 (42.9); culmen, 12-12.5 (12.2). 



A young female about half grown, taken by Dr. Abbott at Prahmon, 

 Trang, February 24, resembles the winter adult above; the breast is 

 tinged with primrose yellow; the flanks are chamois; otherwise like 

 the parent. 



Dr. Smith seciu-ed three older young, about adult size, but still with 

 the yellow tinge to the breast. The3^ were taken at Bangnara, 

 July 13, Kao Luang, July 17; and Nong Mong, August 23. He 

 also took a young bird, slightly younger than the one taken by Dr. 

 Abbott at Doi Hua Mot, August 29. It is deeper yellow on the 

 breast than Dr. Abbott's specimens and the bill is smaller and lighter 

 colored. 



The form ranges from the Malay States through Peninsular Siam 

 to western, northern, and eastern Siam, Tenasserim, Burma, Yunnan, 

 and southern Annam. It has been taken pretty much all over Siam, 

 including the Peninsular section, and seems to be resident wherever 

 found. 



De Schauensee,'''^ in commenting on a series from Chiengmai and 

 Chiengdao, says that it is found up to 5,500 feet where there is long 

 grass. Herbert ®' records it breeding at Bangkok and Samkok in 

 July and describes the eggs. 



It must breed very early in the Peninsula, as witnessed by the 

 young collected bj'^ Dr. Abbott cited above, though a slightly younger 

 bird was taken by Dr. Smith in August. 



MEGALURUS PALUSTRIS ANDREWSI Banga

Two males. Bung Borapet, June 21, 1931, March 25, 1933 ; two males 

 Rangsit, May 5, 1929. 



These specimens are larger than the only Javan male with which they 

 have been compared. This seems to be the only constant character. 

 A series from the Philippines in size is nearer the Javan form than 

 that from the mahiland. One male from Java measures: Wing, 95.5; 

 culmeu, 17 mm. Ten males from the Philippines: Wing, 97-102 

 (98.8); culmen, 16.5-18.5 (17.8) mm. Four males from Siam: Wing, 

 100-105.5 (102.6); culmen, 18-20 (19.2) mm.
