Hah. North-western Australia. 



Five specimens of this bird are in the Museum, brought by Dr. Elsey 

 during the expedition to North-western Austraha. Some of them were 

 determined by the late Mr. G. R. Gray as A. perspicillafus, and some as 

 A. cinereus. They appear to me to be neither the one nor the other. The 

 white tips to the under tail-coverts and the two entirely black central tail- 

 feathers sufficiently prove that they are not A. perspicillatus. From A. cinereus 

 the females of the north-western bird are more difficult to tell ; but they are 

 smaller, and do not have the black so extended on the cheeks ; and this 

 character seems to prevent their being A. melanops.
