ground, and very difficult to obtain, being placed upon the face of 

 an almost perpendicular rock ; upon visiting the same place the 

 following year in the month of October, he found that the same(?) 

 pair of birds had repaired the old nest, and that it contained a 

 single fresh egg, but when disturbed again by his climbing to it, 

 they abandoned it, and built a new nest a few yards higher up, 

 out of reach, the rock on which it was placed completely 

 overhanging thie site of the old nest. 



The eggs are two to three in number for a sitting, of a warm 

 flesh or ruddy ground colour, almost obscured by freckles, spots, 

 and confluent patches of a rich reddish-brown, in a few places the 

 spots are nearly black. Length (A) 2-1 x 1'64 inch; (B) 1'97 x 

 ^:65 inch ; (C) 2-1 x 1-57 inch. 



An egg taken by Mr. Bennett from the same nest the following 

 year, and which he kindly gave uie, is of a very light variety, the 

 ground colour being pinky-white, with reddish-brown or light 

 chestnut markings, confined to the smaller end of the egg. Length 

 2-1 x -6 inch. 



The eggs of this species are usually laid during the months of 

 August and September.

" This is a rare species not plentiful in any part of Australia, 

 but occasionally obtained in the northern portion of the interior 

 of Queensljand, and Mr. Gould records it from Western Australia. 

 I am indebted to Mr. J. B. White for specimens of the eggs taken 

 on the upper Thomson River in Queensland."
