1 We have very large series of this bird from Malaysia but are still a 
little doubtful about the name of the Sumatran race : it is really intermediate 
with a leaning to the Javan form on balance of characters . In Sarawak 
a form very near to trivirgatus and quite distinct from kinabaluensis occurs. 
It seems likely that further material will show it to be rather brighter than 
typical trivirgatus . 
3 Diverse opinions have been published about this form. I have now seen 
about one-hundred birds from Mt. Kinabalu. Normally, kinabaluensis is a 
rather dull, olive-green race, much duller when in worn plumage and always 
very different from typical trivirgatus. At the top of the mountain I collected 
birds quite grey in colour, without a trace of yellow, or green in the plumage. 
The question is complicated by the fact ’that rare mutants (not merely birds 
in very fresh plumage) occur which in colour are inseparable from S. t . tirvir- 
gaius .
