THE BIRDS OF NORTHERN THAILAND 143 



lector obtained a fine specimen at the neighbourhood of Koon Tan 

 during my stay there in April 1914." 



The fate of this important specimen is unknown. I failed to un- 

 cover it in Hannover, and there is no evidence in Stockholm to indi- 

 cate that it ever formed part of the collection there. Since this is a 

 Malaysian form that apparently scarcely ranges beyond Trang Prov- 

 ince, its occurrence in northern Thailand is so extraordinary that I 

 should consider the record erroneous had not Count Gyldenstolpe, 

 in 1939, reaffirmed to me his belief in its correctness and shown, by 

 reference to his early notes, that he had every reason to be certain 

 of his identification. 



It is to be hoped that sportsmen in our provinces will endeavor to 

 rediscover the species, both to confirm the published report and to 

 disclose whether an unnamed subspecies is resident in the northern 

 hills. 



The male has the upperparts grayish olive-green ; the wings slate- 

 gray, crossed by a narrow bright yellow bar; the breast bright golden- 

 orange ; the under tail coverts deep maroon ; the remaining underparts 

 light olive-green. The female has a greenish-yellow wash on the breast 

 and the under tail coverts pale buff with dull brownish centers. 



This is the largest of the treronine pigeons, with a notably heavy 

 bill.

The smaller thick-billed pigeon is a common and widely distributed 

 form but is not likely to occur throughout the year at any one locality, 

 since the flocks wander extensively in search of food. In Hannover 

 is a skin taken by Eisenhofer at Pha Hing, May 9, 1912. The same 

 collector sent to Stockholm five undated specimens, including a 

 juvenile, from Khun Tan. Fejos took a male at Doi Chiang Dao, 

 April 15, 1938. Gyldenstolpe's examples from Ban Huai Horn were 

 males, collected February 13 and 25, 1912. For Chiang Mai I have 

 only two records: A couple of males bought alive in the market, 

 October 30, 1931, and an immature female, taken May 16, 1935. I also 

 have this species from the following places : Chiang Saen Kao, Janu- 

 ary 19, 1937; Ban Mai Tong Hong, May 2, 1936; about 5 km. south of
