1 On the mountains of West Sarawak (Foi and Fenrissen) there is a race 
of A . pyrrhogenys very variable in general colour, some specimens being 
as pale as A. p. cantcapilla and others as dark as A . p. longstaffi j but with 
the forehead and crown paler than in these two races. A faded specimen of 
this race is rather more rufous above than the old type of erythrote , but the 
birds are sufficiently alike to justify the adoption of the name as proposed 
above.
