Ropinson & Kross : Birds of West Sumatra. — 337 
This series shows much variation in the tone of grey 
of the foreneck which can be matched in all cases by birds 
from the Malay States. We do not therefore use croceo- 
ventre V'gors, for the Sumatran bird (cf. Hartert, Bull Brit. 
Orn. Club, XXXVIII, 1918, p. 74). 
The immature birds differ from the adult female in 
being greener throughout : the young male has a spot of 
orange on the breast.

The immature females are rather duller below than 
the adult with less whitish throats and lack the orange 
patch on the crown. , The young male agrees with the 
young females but is becoming blue above and has a small 
orange-red spot on the foreneck. 
Not uncommon at the edge of clearings in old forest.
