upper breast are dark grey and not glossy black. Young 
males are like the females, and young birds of both sexes have 
the under wing coverts and axillaries obscurely barred with 
black and grey and the under tail coverts with whitish edges 
and darker grey subterminal borders. In fully adult birds of 
both sexes the under wing coverts and axillaries are apparently 
uniform grey. 
The speciés is very closely allied to Avtamides normant, 
Sharpe, from Kinabalu, North Borneo (Ibis, 1887, p. 438; id. 
op. cit. 1888, p. Igo), and the females are probably almost 
indistinguishable. The Kinabalu bird, however, has the crown 
and nape of the male grey like the rest of the plumage and 
not glossy black as in the present species.

The females in this series, which are possibly not quite 
adult, agree sufficiently well with the original description by 
Raffles, whose specimens probably came from Bencoolen, 
about a hundred miles to the south of the present locality. 
Compared with four specimens from Sarawak, no differ- 
ences can be detected except a slight superiority in size of the 
bills of the Bornean specimens. 
Fairly common at Sungei Penoh and Sandaran Agong, but 
replaced at higher elevations by P. montanus and P. miniatus. 
The range of this species is not well made out, but from 
the series in the F. M.S. Museum it would appear that it is 
found in the southern half of the Malay Peninsula as well as 
in Sumatra and Borneo. Males are almost indistinguishable 
from those of P. flammifer,t except by a slightly smaller average 
size. Females, however, seem to differ by the more olive tint 
of the yellow of the rump and upper tail coverts and the
