May-2nd June, 1914. [Nos. 1690, 1722, 
1728, 1749, 1844-6.] 
“ Adult, iris carmine, bill dark sage green, blackish brown 
on the culmen and shield, feet yellowish brown; in younger 
birds the irides are brown.” 
Very common throughout the Korinchi Valley among the 
vegetation by the edges of ditches and rivers and on the shores 
of the lake. 
If the present series is laid out against a series of birds 
from the Malay Peninsula it will at once be noted that the 
Sumatran birds are very much greyer on the back than the 
peninsular ones and almost lack the strong bronzy tint on the 
rump and upper tail coverts of the latter. These differences 
are noted by Stresemann (Joc. cit.) and are sufficient to justify 
his separation of the Indian and Chinese bird as A. ph. chinensis 
(Bodd.) from the Sondaic form, A. ph. javanica, apart from 
the factor of size. 
Eleven adults from Sumatra range from 170 to 134 in 
wing measurement (females being very much smaller), with an 
average of 144.4, while eight adults from the Malay Peninsula 
with a range of 170-151 average 160.5 mm. Stresemann’s 
averages for the two subspecies based on large series from the 
entire range are 149.5 and 163.1 respectively.
