102 BIRDS OF BRITISH BURMAH. 



the others black at base and broadly white at tip ; wings blackish, all the 

 coverts, the tertiaries, the outer webs of the secondaries and the outer web 

 of the first primary barred with white ; the outer webs of the other pri- 

 maries narrowly edged with white. 



The female has the head brown, tinged with rusty on the throat, and the 

 lower plumage a paler crimson; the tail is the same as in the male ; the 

 bars on the wings are buff instead of white; the rump and upper tail- 

 coverts are like the back, but washed with crimson. 



Legs and feet pale smalt-blue, smalt-blue, dark purplish blue ; claws 

 horny ; irides deep brown ; bare space over eye deep to bright smalt-blue ; 

 gape to within half an inch of tip of bill a rich cobalt, shading to pale 

 cobalt at tip of lower mandible ; tip and ridge of culmen and a narrow 

 streak on each side horny black ; or, gape and sides of bill cobalt-blue ; 

 culmen, tips of upper and lower mandibles, and edges of both for about 

 one third of their length, measuring from the tip, black. (Davison.) 



Length 10 inches, tail 5'4, wing 4'2, tarsus *4, bill from gape '9. The 

 female is of much the same size. 



A closely allied race, H. orrophceus, Cabanis, occurs in the south of the 

 Malay peninsula. It has the rump and upper tail-coverts not crimson, 

 but concolorous with the back. 



DuvauceFs Trogon occurs from the extreme south of Tenasserim up to 

 NAvalabo mountain, and appears to be not uncommon. 



It extends down the Malay peninsula and is met with in Sumatra and 

 Borneo. 



Mr. Davison says : "In habits it resembles the other members of the 

 genus, inhabiting the most shady depths of the evergreen forests, sitting 

 quietly on some low branch, from which it occasionally swoops off to seize 

 an insect, and at intervals uttering its soft note, which much resembles 

 that of the other Trogons, but is much softer."
