BIRDS FROM SIAM AND THE MALAY PENINSULA 343 



males and five females, Mergiii Archipelago (Sullivan Island; February 

 2 and January 4; St. Alattliew Island, January 14, 16; St. Luke Island, 

 January 19; Loughborough Island, January 23; Ross Island, March 5; 

 Heifer Island, March 6; Bentinck Island, March 10; all except one in 

 1900, this exception being a female collected with a nest and two eggs 

 on Sullivan Island, January 4, 1904). Beside the nest just men- 

 tioned, he collected another nest and two eggs in Trang, March 8, 1897. 



He describes the soft parts as: Iris pale brown, olive-brown, or 

 yellowish brown; bill dark horn brown, blackish or dark leaden above, 

 leaden, leaden blue or bluish white below, paler near tip; feet pale 

 brownish fleshy or pale fleshy. 



The series from Tenasserim and the Mergui Archipelago seem to 

 have a little more russet tinge to the upperparts and average slightly 

 larger than the series from the Malay Peninsula from Bandon south. 

 I have seen few birds from the Federated Malay States, however. 



The differences are slight and hardly worth recognizing by name. 

 The eastern and southeastern Siamese series agree with the series from 

 Peninsular Siam in size and color rather than with Tenasserim birds. 

 The single male from Koh Lak and the two males from Lamton Lang 

 are much worn and considerably lighter than the remainder of the 

 series. 



The above large series represents the Siamese range of this bird 

 quite satisfactorily, except there are no specimens from northern 

 Siam. The species has quite an extensive range, extending from 

 Nepal, Sikkim, Assam, and Burma to the Malay Peninsula, Siam, 

 and Cambodia. 



In the Malay States a form of Malacocincla sepiaria is found. 

 Several races described as forms of M. abbotti are really forms of M. 

 sepiaria. It is very doubtful if any form of M. abbotti occurs south of 

 the Malay Peninsula.

 1,000-2,000 feet, February 5-18, 1899. He gives the soft parts as: 

 Iris dark brown or dark red; orbital skin dark blue; bill dark horny, 

 leaden blue, or black above; leaden beneath; feet fleshy brown. 



Chasen and Kloss record it from Hue Nya Pla, in the Raheng Dis- 

 trict, western Siam,*^ and one of the specimens, a male, was acquired
