536 jMr. G. L. J5ate.s on the 



adults ill the plumage of the throat and chest, and in the 

 colour of the bill. The bill is black or red mixed with black, 

 while in the adult it is entirely red ; the black throat-plumage 

 is mixed with a yellowish-brown colour like that of the belly, 

 and there is a tinge of the same colour on the white chest. 



It was a mistake when T spoke of the " yellow iris " of 

 birds of this species. The conspicuous yellow colour is not 

 thiit of the iris, but of t'.ie ball of the eye, outside the iris ; 

 the latter is dark brown. 



A small flock of these birds was observed day after day 

 near ray camp at Assobam. They were always seen near 

 the same place moving from tree to tree in a sluggish way, 

 one at a time, and then sitting for a long time motioidess. 

 One of the sounds made by them resembled the '^ swishing " 

 of a switch; this was made with the mouth while the birds 

 were sitting still. They also make a snapping noise with the 

 bill. A specimen that was brought to me alive, having been 

 merely knocked down by the little arrow, made this loud 

 snapping noise.

Tao young birds, one half-fledged and still in the nest, 

 and one wliich had just left the nest, had the j)luinage much 

 like that of the adult. In each the tongue and the inside of 

 the mouth were bright orange, while the swollen margin of 

 the gape was white. 



The majority of the nests with eggs have been found in 

 the month of August, but nests with eggs or nestlings have 

 also been obtained in September and October, as well as 

 in March. The principal rainy season begins at the end 

 of August, and it is probable that insects are most abundant 

 at that season. 



The number of eggs in a nest was always two. Seven eggs 

 not included in the former description vary in length from 

 2o'5 to .2.2 mm , and in width from 18 to 16'5 mm. 



[ riiese eggs much resemble those already described, and 

 are quite of the same type as those figured in the ' Catalogue
