not obtained. Thinocorys orbignyanus was met with at 18,000 
feet. Only one Duck, Anas cristata , is mentioned. 
The second list enumerates 11 species obtained at Lujan, 
15 miles south of Mendoza, and contains nothing remarkable. 
iC Lamprotes bonariensis ” is, we suspect, an error for 
“ Tanagra darwini ” for the former is a Brazilian species 
which would not be likely to occur in Western Argentina. 
44. Hall on Australian Birds. 
[A Key to the Birds of Australia and Tasmania, with their Geo¬ 
graphical Distribution in Australia. By Robert Hall. 8vo. Melbourne 
and London, 1899.] 
This appears to be a useful manual of the 767 known 
birds of Australia, with special reference to their distribution. 
The nomenclature and arrangement of the British Museum 
Catalogue are adopted. The continent of Australia is 
divided into the “ Eyrean,” “ Torresian,” and £f Bassian ” 
subregions, as proposed by Prof. Spencer; and these sub- 
regions are again separated into nine ‘ £ areas,” which are 
designated by numbers and are so indicated for the localities 
of the species. It would have been better, we think, to have 
added references to all the species not included in the B. M. 
Catalogue (e. g. Stipiturus ruficeps ), to avoid any difficulty 
in finding them. 
45. Hall on the Changes of Plumage in Malurus. 
[Notes on Malurus gouldii and Malurus cyaneus, with special reference 
to Changes in Plumage. By Robert Hall. Proc. R. Soc. Victoria, new 
ser. xii. (1899) p. 59.] 
The author discusses the vexed question of the changes of 
plumage in this genus at some length, and considers that the 
annual double moult of the male is now an established fact.

Hinterland, by Capt. W. Giffard. Nov. Zool. vi. p. 403 (1899).] 
There is still much to be done in working out the exact
