1 This race needs confirmation : as some recent authors have remarked 
the bird from the Malay States ought to be separable, but Robinson who 
worked through the species in 1927 saw no reason for separation and I have a 
recollection that he once told me that he could not separate a Malayan sub- 
species. I have never seen fresh skins of true erythrocephalus .
