184 BIRDS OF THE 



life cobalt, tip pale green (after death the cobalt-color changes 

 into green and becomes black in dried skins), edge of upper 

 mandible black, lower mandible green, feet pale flesh-color. 

 Hab. From Tenasserim throughout the Malay Peninsula 

 to Sumatra and Borneo, where it is generally distributed.

A great number of adult, immature and young speci- 

 mens of both sexes from Pontianak, Poetoes Sibau, Nanga 

 Raoen, the Siniai Valley, and Poelau. — Iris green in 

 adult birds, in younger specimens purplish gray or brown ; 

 bill in adult birds uniform cobalt-blue, in younger speci- 

 mens pale green, edge blue, followed by yellow, in quite 

 young birds pale green with blackish tip, lower mandible 

 with blue edgings, followed by green, and yellow in the 

 centre, in young specimens entirely rosy ; feet purplish 

 blue. Two fledged young birds have breast and abdomen 

 barred with rosy-red and grayish brown, but in the male 

 the throat is blackish, while in the female this part is 

 yellowish white, which color is separated from the barred 

 breast by a dusky blackish broad bar across the chest. 

 The red color on the rump and the white shoulder-coverts 

 are plainly developed, but the black color of the upper 

 surface yields to a brownish tinge and is destitute of any 

 gloss. The white on the inner edge of the outer tail-feathers 

 varies very much in extent and in some specimens is even 

 entirely wanting. This difference seems to me quite individual, 

 and not due to locality, age or sex of the bird (see also 

 my explanations in N. L. M. 1887, p. 43). 



Hab. Malay Peninsula, Sumatra, Banka and Borneo, 

 where it is spread over the whole island, keeping by prefe- 

 rence to the banks of the rivers.
