Batavia error = Sumatra. 
Distr. — Malay Peninsula. 
Sumatra. 
* The type locality is neither Travancore, selected by Baker in 1922, 
nor the Malay Peninsula selected by Robinson and Kloss in 1923. The 
species does not occur in China as originally stated but an additional locality 
“Strat Sunda" was provided in Syst. Nat. 1766, i, p. 153 ; since the bird 
is not found in Java on the east side of the Sunda Straits the type locality 
is therefore “Sumatra". If, as Baker states (F.B.I. Birds, 2nd ed, 4, 1927. 
p. 284) the Sumatran and continental races are separable {the few we have 
seen from Sumatra seem like Malayan birds) then the latter must bear the 
name cavatus Shaw : Philippines error = Tndta f Baker, 1Q30).
