Iris white, bill pinkish horn, feet maroon brown. 
Common in swampy situations on the edge of jungle in 
the Korinchi Valley and also in jungle clearings in the hills, 
but not apparently ascending above 5,000 feet and not congreg- 
ating in so large flocks as M. leptogrammiica. 
A comparison of five adult males in the above series with 
ten equally adult specimens from various parts of the Malay 
Peninsula shows that the two series differ considerably inter se. 
The Sumatran birds are considerably darker on the breast, the 
lateral black spots on the feathers being much more in evidence 
and the white tips much less conspicuous than is the case with 
the peninsular birds. On the upper surface the Peninsular 
birds are much more uniform brown on the mantle, the edgings 
to the feathers not being conspicuously lighter than the rest as 
is the case with the Sumatran bird, while the metallic gloss on 
the nape in the island form is greenish, showing as a distinct 
bar on the feather, while in the Malayan bird it is a generally 
distributed amethystine gloss. 
Stresemann, in his careful review of the species, has 
grouped the birds from the Malay Peninsula, Sumatra and 
Borneo as one subspecies. The present material does not bear 
out his conclusions and though for the present we have followed 
him we think that it is more probable that birds from West 
Sumatra are identical with the typical Javan form, while the 
peninsular birds are either identical with M. ruficeps assimilis, 
Hume, from Tenasserim,-or are to be regarded as yet another 
subspecies. It is at anyrate certain that the two series now 
before us cannot be referred to the same form. The dimen- 
sions of the series afford no assistance. The average of the 
five Sumatran birds is 143.2, while those of the adult males 
from the Malay Peninsula is 141.1, figures in both cases slightly 
higher than those of Stresemann, which 1s due to the fact that 
he has probably included birds of both sexes and of various ages 
in his series.
