than the Malaccan. The tint of the upper surface varies from a 

 strong olive-brown to fulvous-brown or even nifous-brown, the latter 

 phase accompanied by a chestnut tail. I imagine that these rufous 

 birds may be the young, as I have specimens before me both 

 from Malacca and Borneo, and it is impossible to believe that 

 they represent a distinct species. The bill is much paler in the 

 rufous-coloured birds, and the under mandible conspicuously yel- 

 low, which appears to be another sign of nonage in a Timeliiue 

 bird. 



Another point of difference between specimens is to be seen in 

 the distribution of the colour of the uuderparts. In some the white 

 of the throat is continued unbroken to the abdomen ; in others there 

 is a faint shade of rufous on the chest ; while in others the whole 

 chest is orange-rufous, cutting off the white throat from the white 

 abdomen.

It seems doubtful, however, whether the sexes of these examples 

 are correctly determined ; for two birds collected in Borneo by Mr. 

 A. H. Everett measure : —
