1867. J MR. p. L. SCLATER ON CHILIAN BIRDS. 319 



The collection of birds contains nothing remarkable, except a 

 Pitta not hitherto recorded from Australia — P. mackloti, Temm. I 

 may also observe that the northern Pitta strepitans is not only a 

 much smaller bird than the southern one, but differs considerably in 

 the markings, and the shape of the bill and feet. The blue spot on 

 the shoulder is comparatively larger, the colour of the head lighter 

 brown, and, whilst the P. strepitans of New South Wales has from 

 three to four white spots on the primaries, the northern bird has 

 only two. 1 wish to draw the attention of ornithologis'ts to these 

 facts, as I have seen only a single specimen of P. strepitans from 

 Cape York. 



2. Notes on the Birds of Chili. By P. L. Sclater, M.A., 

 Ph.D., F.B.S., Secretary to the Society. 



Messrs. Philippi and Landbeck, of the Museum of Santiago in 

 Chili, have been kind enough to supply me with typical specimens 

 of a certain number of the new species of Chilian birds recently de- 

 scribed by them in Wiegmann's * Archiv fiir Naturgeschichte,' along 

 with other specimens of birds from that country. It has been of 

 the greatest interest to me to examine these specimens, and to com- 

 pare them with examples in my own collection and that of Mr. 

 Salvin ; and I beg leave to communicate to the Society the following 

 notes on them. 



The most recent summary of Chilian ornithology is that given by 

 Dr. Hartlaub in 'Naumannia' for 1853. Dr. Hartlaub has there 

 enumerated the principal sources of our knowledge of the avifauna 

 of this country. As more recent authorities to be consulted on this 

 subject I may add : — 



(1) Mr. Cassin's article on the Birds obtained during the U. S. 

 Naval Astronomical Expedition to the Southern Hemisphere, under 

 the command of Lieut. Gilliss, published in the second volume of 

 the Report of that Expedition*. Washington, 1855. 



(2) Herr v. Pelzeln's volume on the Birds of the Novara Expe- 

 dition. Wien, 1865. 



(3) Dr. Philippi and Herr Landbeck's numerous articles in 

 Wiegmann's 'Archiv fiir Naturgeschichte' f.
