Carl Johan (Ove Monster) Aagaard (1882- ), a longtime 

 Danish resident of Thailand, made two trips to the North to collect 

 chiefly birds and mammals : The first, to Chiang Mai and Doi Suthep, 

 in February and March 1931 ; the second, to Doi Ang Ka, about one 

 year later. The nearly 400 bird skins obtained on Doi Suthep were 

 discussed by Chasen and Boden Kloss in 1932 ( Journ. Siam Soc. Nat. 

 Hist. Suppl., vol. 8, No. 4, pp. 231-248), but nothing was ever pub- 

 lished concerning the fruits of the Ang Ka expedition, among which 

 is the only specimen of Cinclus yet taken in the Kingdom. Aagaard's 

 specimens are widely scattered among the museums of the world, but 

 his most important finds remained in his private collection, which 

 eventually came into possession of Chulalongkon University in 

 Bangkok. 



In 1937, at the Raffles Museum in Singapore, I examined a small 

 collection of bird skins, from the vicinity of Chiang Mai and Chiang 

 Dao, that had been sent for purchase by one Nai Kaeo (1906?- ), 

 a resident of Ban Den, an out-village of Chiang Mai. The birds seen 

 had been taken in 1936 and 1937, and it is probable that later sendings 

 arrived at Singapore. Among them were several forms not pre- 

 viously recorded from the district, mention of which is made at 

 the proper places in my text. 



The Asiatic Primate Expedition spent the period between February 

 16 and April 30, 1937, in the province of Chiang Mai, and one of the 

 party, J. A. Griswold, Jr., with the assistance of Asiatic collectors, 

 during that time took more than 1,000 specimens of birds that were 

 later to be deposited in Cambridge at the Museum of Comparative 

 Zoology. A report on a part of this material was brought out by 

 J. C. Greenway, Jr., in 1940 (Bull. Mus. Comp. Zool., vol. 87, No. 3, 

 pp. 167-194). The pertinent collecting localities and dates are as 

 follows : 



February 16-26, 1937, Chiang Mai, Chiang Dao, Doi Saket. 

 February 26-April 27, 1937, Doi Ang Ka. 

 April 8-23, 1937, Doi Nang Kaeo. 

 April 26-28, 1937, Chiang Dao. 

 April 29, 1937, Chiang Mai. 



In March and April 1938, the Swedish Film Industry Expedition, 

 under the leadership of Dr. P. Fejos, a Hungarian, engaged Deignan's 

 old collector, Charles Tan, to make a collection of bird skins for the 

 Royal Museum of Natural History in Stockholm. Some 90 skins were 

 taken, among them two specimens of the short-eared owl, which had 

 not previously been known from our area. The whole collection seems 

 to have come from Chiang Mai Province; the pertinent localities and 

 dates are as follows : 



March 12-14, 1938, Chiang Mai. 



March 17, 1938, Chiang Mai, Huai Chang.
