Dr. W. L. Abbott collected, in 1900, two males and five females in 

 the Mergui ArcMpelago (St. Matthew Island, January 14; Domel 

 Island, February 27; Bentinck Island, March 9-10; High Island, 

 December 31) and a male at Tanjong Badak, Tenasserim, January 

 7, 1900. This is the series upon which the name M. g. archipelagica 

 cited above was founded. I am inclined to lump these with connect 

 tens also. They can be matched in plumage by birds from southeastern 

 Siam; the bills average a httle larger, but there is not sufficient difTer- 

 ence to warrant a new race. 



Three males from Mergui and Tenasserim measure: Wing, 55-62.5 

 (59.2); tail, 47-54 (51.3); culmen, 14.5-15 (14.8) mm. Eight males 

 from Trang: Wing, 58-62 (60.2); tail, 49-57 (52.5); culmen, 14-15 

 (14.5) mm. Ten males from northern Peninsular and southeastern 

 Siam: Wing, 55-61 (57.6); tail, 48-54.5 (50.7); culmen, 13-14.5 

 (14) mm. 



The form ranges from Patani in Peninsular Siam north to southern 

 Tenasserim, the Mergui Arcliipelago, extreme southern Siam to 

 southeastern Siam, Cambodia, Cochinchina, and southern Annam, 



Herbert ^^ found it breeding around Bangkok in May and June 

 and has described the nest and eggs.

This series covers the range of this form fairly well as far as Siam ia 

 concerned. De Schauensee " found it at Chiengmai, Chiengrai, and 

 Chiengsen, and later at Chiengdao. Deignan " says it is common on 

 the plain at Chiengmai and ascends Doi Sutep to 3,500 feet. 



The range of the form is from the southern Shan States, Burma, 

 and southern Yunnan south into western, northern, and eastern 

 Siam and east to western Laos. My statement for the last locality
