Mr. Gould's specimen seems scarcely adult, as the black of the 

 face is not strongly pronounced, and one in the Cockcrell collection 

 has dusky spots on the throat, which Mr. Gould says are wanting 

 in the species. A specimen in the Cockerell collection agrees with 

 Mr. Gould's type and differs from the bird described in having the 

 sides of the face and ear-coverts greyish, and in having the under- 

 parts generally paler.
