unfortunately I failed to bring the bird down, and they were 

 not afterwards seen. This Eagle has a rather loud call ; it - 

 has a beautiful soaring flight, often in ascending circles." —

The type-specimen of this small Booted Eagle, an adult 

 female, was procured by Emil Weiske in the Astrolabe Moun- 

 tains, British New Gruinea, at an elevation of 3000 feet. It 

 was described by Dr. Reichenow and subsequently purchased 

 by the British Museum. A second adult specimen in the 

 Museum Collection obtained by A. Goldie in the Choqueri 

 District, Astrolabe Mountains, closely resembles the type- 

 specimen, but is smaller, the wing measuring 298 mm. 

 (=11-7 ins.) as compared with 317 mm. (=:12'5 ins.). The 

 sex of this smaller specimen has not been ascertained, but 

 it is no doubt a male. 



The young male procured by the Wollaston Expedition is 

 in first plumage, with the downy plumes still adhering to 

 the tips of some of the quills and tail-feathers. It has the 

 general colour of the under parts tawny rufous, somewhat 

 paler on the belly, thighs, and under tail-coverts. The 

 throat, breast, and sides of the body are rather heavily 

 streaked with blackish as in the adult birds, but in these the 

 ground-colour is creamy-white. In the young bird all the 

 ends of the feathers of the top of the head and back of the 

 neck are reddish-brown, or deep tawny-red with dark blackish 

 middles and narrow white tips ; the basal half is pure white, 

 as in the adult, but in the latter the ends of the feathers of 

 the crown and nape are blackish-brown. In other respects 

 the young bird resembles the adult, but the sinuation on the 

 eclge. of the upper.mandible is wanting. ....-- .
