BIRDS FROM SIAM AND THE MALAY PENINSULA 155 



The form has been recorded from northern Siam south through 

 Peninsuhir Siam to the Malay States. Herbert ^^ reports it breeding 

 at Samkok, the eggs being deposited from February to August 13. 

 Dr. W. L. Abbott took a set of two eggs at Mahwun, Tenasserim, 

 March 8, and another set of two eggs at Telok Besar, Tenasserim, 

 March 14. 



The race is apparently resident where found and ranges from Assam, 

 Burma, Yunnan, and southwestern Cluna, south to Siam, the Malay 

 Peninsula, and Indo-Chiua. Other forms occur on the islands from 

 Java south to AustraHa and in India.

Caprimulgus jotaka Temminck and Schlegel, in Siebold's Fauna Japonica, Aves 

 p. 37, pis. 12, 13, 1847 (Japan). 



One female, Mekhan, February 8, 1932. 



This form breeds in Japan, the greater part of China, and the hills 

 of Assam and migrates south as far as New Guinea to winter. In 

 Siam it has been recorded as a migrant from Teratau, Langkawi, and 

 Trang.

Caprimulgus rnonticolus burmaniciis Baker, Bull. Brit. Orn. Club, vol. 51, p. 102, 

 1931 (Upper Chindwin, Burma). 



Dr. W. L. Abbott collected an adult female at Champang, Tenas- 

 serim, December 20, 1903. 



In this specimen the chest is marked with sagittate spots of cinnamon, 

 and the feathers of the hindneck have a rather broad orange-cinnamon 

 central stripe at the tip, forming an UTegular coUar. Wing, 187 mm. 



This nightjar can be readily distinguished from the other forms 

 inhabiting Siam by the two outer tail feathers in the male being mostly 

 white, only the extreme tips mottled dusky. In the female the outer 

 tail feathers are dusky mottled cinnamon, with irregular black bars. 

 It is larger than asiaticus. 



The range assigned this form by the describer is Silvkim to eastern 

 Assam, eastern Bengal, the whole of Burma, Siam, Cambodia, and 

 Cochinchina. De Schauensee reports taking a female at Nakon 

 Nayok ^* and on his third expedition he secured it at Chiengmai and 

 Tamuang.^^ Baker ^^ records it from Paknampho; Barton " from the 

 Raheng District; Lowe ^^ from 20 miles west of Kempempet. Gylden- 

 stolpe ^^ says that it has been met with only in the northern parts of 

 Siam and seems to be rare. Apparently it is resident throughout the 

 year.
