The small cuckoo dove is apparently rare in northern Thailand and 

 so far is known only from the localities listed above. It seems to be 

 confined to the mountain evergreen above 3,500 feet. 



A specimen taken on Doi Suthep, September 10, had the gonads 

 greatly enlarged. 



Examples taken by me had the irides gray ; the orbital region plum- 

 beous-gray ; the bill pinkish brown ; the feet and toes brownish pur- 

 ple; the claws horny brown or brownish purple. De Schauensee re- 

 cords that a male had the irides white ; the bill black ; the feet and toes 

 deep crimson. 



The adult male has the crown rufous ; an indistinct collar, beginning 

 at the sides of the breast and crossing the hindneck, violet-brown 

 glossed with violet and greenish ; the outer rectrices bright red-brown 

 with a broad subapical black bar; the remaining upperparts dark 

 brown, the wing coverts, scapulars, and feathers of back and rump 

 margined with bright red-brown ; the entire underparts light rufous, 

 paler on the throat, the feathers of the breast tipped with white or 

 whitish and sometimes with partly exposed blackish bases. The adult 

 female lacks iridescence on the neck and has the breast more mottled 

 with black or blackish.
