clearer blue grey, and the rufous of the under surface deeper in 

 tint than in the Australian specimens ; the bill is larger, the

Astur cruentus ; Sharpe, Jour. Limi. Soc. Zool. XIII, p. 488. 



Several specimens obtained, forming a good series of adults 

 and young, in which the characteristic markings of the immature 

 birds of the genus are well exhibited. 



This species takes the place of Astur approximans of Aus-

 Specimens were contained in every collection made at this place. 

 The young are mostly covered with white or creamy down, but 

 before they are six months old attain a spotted plumage similar 

 to the adults.

 In Mr. Goldie's first collection there was a species of Ninox, 

 a fledgling, which I previously described in the Pr. L. Soc. 

 of N.S.W., vol. I., p. 338, and respecting which I regret no 

 further information has been obtained ; however, I believe this 

 to be the young of Ninox dimorpha, of which we have received a
