Remarks. — This new race differs from Cyornis elegans elegans from 

 western and northern Sumatra in the paler ochraceous of the breast, and 

 the more whitish lining of the wing in the male; and in the slightly darker, 

 less greenish, upper parts and less deeply rufous lower parts of the female. 

 It is apparently confined to Borneo.
