BIRDS OF TENASSERIM. 63 



are buff to deep ferruginous ; tail feathers black, with broad 

 mottled transverse bars, the upper portion of each bar being 

 pale to bright ferruginous buff, and the lower portion much 

 paler, almost pure white in some specimens. 



The mantle is a constantly varying combination of a paler 

 color varying from nearly white to rich buff, most delicately 

 pencilled all over black, and more or less spotted with black, 

 and with black mottled and margined with deep ferruginous 

 in no two specimens that I have met with are the* backs 

 precisely alike. 



Mr. Gould's plate of this species, Icones Avium, Pt II pi 4 

 is extremely good. ' '

Palaw-ton-ton ; Bankasoon j Malewoon. 



Confined to the extreme south of the province, but fairly 

 common in the forests there. ^ 



[This handsome little Trogon is not uncommon, from about 

 midway between Mergui and Malewoon southwards to Johore 

 the extreme point of the Malayan Peninsula. 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 re- 

 sembles that of the other Trogons, but is much softer, and 

 consists of the three syllables, too-too-too, repeated quickly. 

 When suddenly alarmed it has a peculiar note, a sort of kir- 

 r-r-r, which it utters as it takes flight. — "W. D.l 



The following are dimensions and colors of the soft parts re- 

 corded in the flesh from a very large series of specimens ob- 

 tained in the extreme south of the province of Tenasserim : 



Males.— Length, 9"5 to 10*25 ; expanse, 12-5 to 1375; tail 

 from vent, 5'26 to 5-62 ; wing, 4-2 to 4-37 ; tarsus, 035 to 0*45; 

 bill from gape, 085 to 1*0 ; weight, 1-25 to 1*5 oz. 



Females.— Length, 9'25 to 9-62; expanse, 13 to 13-25 ; tail 

 from v.ent, 4-25 to 5-5 ; wing, 4-12 to 4*25 ; tarsus, 0*37 to 0*4 ; 

 bill from gape, 09 ; weight, 1-5 oz. (Only two females mea- 

 sured.) 



The colors of the soft parts do not differ appreciably in the 

 two sexes, but they are, perhaps, slightly duller in the 

 female. 



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 0'5 of tip of bill, a rich
