RAPTORES. 29 



as yet I have only seen four examples, all of which were 

 killed in South Australia. It was observed by Captain Sturt 

 during his expedition into the interior of that country, and he 

 has favoured me with a note, in which he says, " This well- 

 shaped and rapid bird was killed at the Depot, where both 

 male and female were procured; but it was by no means 

 common, only two others having been seen," 



The occurrence of this Falcon in the interior of Australia 

 is an additional evidence of the probability of there being 

 mountainous districts in the unexplored portions of the 

 north-west. Mr. Gurney states that it is also found in 

 New Zealand. 



The original specimen from which Mr. Gray took his 

 description is in the British Museum. 



The entire plumage dark sooty brown, becoming paler on 

 the edges of the feathers of the upper surface ; chin whitish ; 

 irides dark brown; cere yellow; bill lead-colour; legs and 

 feet leaden yellow ; claws black. 



Total length 22 inches ; bill 1 inch ; wings 16^ ; tarsi 2:^. 



Ornithologists who may be desirous of becoming better 

 acquainted with the Falco suhniger will do well to consult the 

 figure in the folio edition of the ' Birds of Australia.'
