Dr. W. L. Abbott collected an immature male, Lay Song Hong, 

 Trang, December 22, 1896. 



This specimen is much lighter above than a male from Borneo, 

 the nape is tinged with rusty, the white in the wing is confined to the 

 greater coverts, the tertials are edged with rusty, and the white line 

 extending back from over the eye is better defined. These dift'erences 

 are possibly due to age. 



Robinson^* records this form from Kao Nawng, 1,200-1,500 feet, 

 Bandon; Robinson and lOoss ^' list two males taken at Tasan, Chum- 

 porn, March 17-24, which is the farthest north that the form has been 

 recorded. 



The race ranges from Borneo to Sumatra, the Malay States, and 

 Peninsular Siam north to Tasan. In the Malay States it is said not 

 to be an uncommon bird at moderate elevations. 0. d. dumetoria 

 (Wallace) inhabits Lombok and Java.
