With the female taken at Bangkok, May 26, 1926, a nest and two 

 eggs were collected, and a nest and one egg were taken at Patalung,

Dr. W. L. Abbott took the following in the Malay Peninsula: Three 

 males and two females, Trang (Prahmon, February 23, March 7, and 

 April 6, 1896; Tijching, May 26, 1896; Trang, January 5, 1897); two 

 males, four females, and one unsexed, Trengganu (Dungun River, 

 September 19, 22, 1900; Tandjong Dungun, September 20, 1900; 

 Kemamun River and Kemamum, October 1, 1900). 



For comparison I have available one male and two females from 

 Java. These when compared with Malay and Siamese specimens are 

 lighter above, especially around the head. 



This form seems to be generally distributed virtually all over Siam 

 and down the Malay Peninsula to the Malay States. It ranges from 

 Burma to Siam, Cochinchina, and Cambodia and south through 

 Peninsular Siam to the Malay States, Sumatra, Borneo, and some of 

 the adjacent islands.
