566 MESSRS. SCLATER AND SALVIN ON [May 23, 



The White-eyed Australian Crow at present in the Society's Gardens, 

 the manners of which were exceedingly like those of the British 

 Jackdaw, was identical with this smaller kind. Length from bill to 

 gape 2| inches, of tail 7^ inches, tarsus 2| inches, and middle toe 

 with claw 2 inches. The larger species was probably that noticed 

 by Mr. Ramsay in the ' Ibis ' for 1865, p. 303, as being distinguished 

 by having a dark-coloured iris. The lanceolate feathers in front of 

 the neck were considerably more developed than in the other ; and the 

 throat was bare of feathers to a much greater extent, having merely a 

 narrow central strip of them. Length of wing from carpus 14| inches, 

 tail 9 inches, bill from point to gape 2| inches, tarsus 2| inches, and 

 middle toe and claw 2~ inches. In the smaller species the bill was 

 more distinctly angulated than in the other ; but in other respects 

 the two bore a near resemblance. 



The following papers were read : — 



1. List of Birds collected by Mr. Wallace on the Lower 

 Amazons and Rio Negro. By P. L. Sclater, M.A., 

 F.R.S., and Osbert Salvin, m'!a., F.Z.S. 



(Plates XXIX. & XXX.) 



Mr. "Wallace having kindly placed in our hands the collection of 

 birds remaining in his possession from his former travels on the Lower 

 Amazons and Rio Negro, we have had great pleasure in determining 

 the species and in compiling the subjoined list of them. As regards 

 the vicinity of Pan! and the Lower Amazons Mr. Wallace believes the 

 series now remaining in his hands to contain specimens of nearly all 

 the species collected, with the exception of the water-birds, some of 

 which have been altogether parted with. But a large part of the 

 collections made on the Rio Negro, as likewise nearly all those from 

 the Upper Amazons above Barra, were most unfortunately lost in the 

 manner mentioned by Mr. Wallace in the Preface to his ' Travels on 

 the Amazon and Rio Negro ' (Preface, p. 4). Some few specimens 

 of Upper-Amazons species still remain in Mr. Wallace's possession ; 

 but we have not included their names in the present list, as the 

 country in which they were collected belongs to a different zoological 

 province. 



Many naturalists have at different times passed up and down the 

 Lower Amazon and Rio Negro, and collected at various points on 

 their banks ; but we are still without anything like a detailed or 

 connected account of the ornithology of the regions through which 

 they travelled. It is in fact only within the last few years that the 

 importance of giving exact localities to objects of natural history has 

 met with the appreciation it deserves. Coming as it does from 

 ground so repeatedly traversed, it was not to be expected that Mr. 

 Wallace's collection would contain many novelties ; and it is there- 

 fore chiefly with the object of elucidating the avifauna of this re- 

 gion, and fixing to exact localities species of which the precise ^ja/rm
