117. Caprimulgus macrurus ambiguus Hart. — Niglitjars were ratlier com- 

 mon in every locality visited dviring ray journey, but as I did not slioot any except 

 in tlie neighbourhood of the Meh Yome river south of the town of Muang Pré, I 

 can not decide with certainty if they all belonged to the same species as tlie birds 

 obtained near the Meh Yome. Here I got a pair and they both rose from the same 

 place — the dry bottom of a small rivulet — when I approached.

118. Harpactes oreskios Temm. — This Trogon was only found in dense 

 forests ronnd T3ang Hne Horn bnt here it was rather common and single individuals 

 were of ten seen in thick and gloomy jnngles. 



It was rather curious tliat I never observed this species either in the forests 

 in the neighbourhood of the Meh Lem river or near the eastern coast of the Gulf 

 of Siarn as both these forest belts are of qnitc the same kind as those at Bång Hue 

 Hom. Around the Meh Lem river I instead found another Trogonid Harpactes 

 erythrocejjhalus Gould. 



The Trogons are very silent and slow and they never showed any shyness, and 

 1 coukl look at them from qnite near at hand. I never heard them utter a sound 

 and their flight is quite noiseless, reminding of that of a Cuckoo, especially when 

 they settle on a branch.

119. Harpactes erythrocephalus Goult). — I only got a female of the Red- 

 headed Trogon near the Meh Lem river when passing through a primeval forest on 

 my way back to my camp at the river, Round the Meh Lem this species was very 

 rare — I only noticed 3 specimens — and I failed to observe it in any other place 

 during my journey. Like Harpactes oreskios Temm, this species is also very silent 

 and not shy and I could come close to it before it showed an intention of escaping. 

 This species extends from Eastern Nepal to Assam and through the Burmese countries
