inactive birds. They are rarely found on lofty trees, but frequent 

 creepers and shrubs of medium size. Nearly all the specimens that I 

 have ever seen were perched motionless on branches and seemed to 

 trust to absolute quiesence to escape notice. Under such conditions, it 

 is extraordinary how difficult it is to make out what one would 

 naturally suppose to be an exceptionally conspicuous bird. Personally 

 I have never heard the note of any Trogon, though I have watched 

 P. duvauceli for lengthened periods. 



P. oreskios is a bird of very restricted range, as regards 

 altitude. Though widely spread in the Malay Peninsula, it is not 

 found below 2,500 ft. or above about 4,000 ft. It is worthy of note 

 that P. eri/throcephaJus does not occur on Gunong Tahan, though it is 

 very common indeed, on the Perak and Selangor mountains. It could 

 hardly have escaped notice as our Dyak hunters, who know the bird 

 well, had special instructions to search for it. — H. 0. R.]

[On cloudy evenings, after rain, this species was seen in consider- 

 able numbers at Kuala Tembeling, usually appearing about half an 

 hour before sunset. A single male only was shot and dissection 

 showed that it had been feeding largely on cockchafers of considerable 

 size, which were swallowed whole. 



This specimen which is in freshly moulted plumage is typical 

 C. gigantea, having the loral spot deep black, but it may be remarked 

 that specimens shot in February and May on the Semangko Pass 

 between Selangor and Pahang at an altitude of about 2,700 ft. have 

 this spot pale smoky brown, in one case almost white, and in this 

 respect approach C. indica. From the same locality the Selangor 

 Museum also possesses a specimen of the rare C. cochin chinensis, Oust., 

 shot by Mr. A. L. Butler in November, 1900. The species is readily 

 distinguished from the allied forms by having the throat and dorsal 

 region pale smoky brown, and also by its considerably smaller size. —
