148 LIST OF BIRDS OF BORNEO. 
having been unfortunately lost. The Lumbidan 
specimen exhibits a fairly well-defined black chin, 
which character does not seem to have been pre- 
sent in the type, of which the throat is described 
simply as white, and it is so depicted in the plate. 
Hence perhaps Mr. Sharpe was led to identify P. 
berte with P. orcas, in which the absence of a black 
chin was deemed by Swinhoe to distinguish it 
from P. nympha of China. There is only a single 
skin of P. xympha in the British Museum and in 
it the chin, which is partly denuded of feathers, 
seems to have been white. Probably when a 
series of skins of the three species can be brought 
together, it will be found that P. dertz is identical 
with P. xympha, the individuals found in Borneo 
being occasional migrants from China.
