into four divisions — the Southern Pampas^ the inter-riverine 

 region {i. e. between the Rio Colorado and the Rio Negro 

 and Rio Neuquen), the central mountain-range, and the 

 eastern slope. The first two of these are discussed at full 

 length and their peculiar animals are descanted upon ; but 

 the third and fourth regions were not touched upon by the 

 expedition, and are in fact almost unexplored. The birds 

 enumerated in the report are 110 in number, most of which 

 are well-known Patagonian species. Dr. Doering contends 

 that the Synallaxis orbignii of Sclater's synopsis (P. Z. S. 

 1879, p. 621) is the true S. flavigularis, Gould, and ought to 

 bear that name. A map of the territory traversed and 

 described in the Report would have much facilitated the 

 understanding of it.

These are supplementary to the paper noticed, 'Ibis,^ 1883, 

 p. 566, and relate principally to the winter dresses of the 

 different species. 



31. Dybowski's Notes on the Birds of Kamtschatka. 



[Hemarques sur les Oiseaux du Kamtschatka et des iles Comandores. 

 Par le Dr. Benoit Djbowski. Bull. Soc. Zool. France, 1883, p. 351.] 



These are mostly field-notes on Kamtschatkan birds. Astur 

 candidissimus, described as a new species, is apparently a white 

 form of A. atricapillus , which is a permanent resident in the 

 country, and feeds on the Ptarmigan in the winter. Hirundo 

 kamtschatica and PhyUopseuste horneyeri are also described 

 as new species, together with two new subspecies of Corvus 

 cor ax — C cor ax kamtschaticus and C. cor ax bericyianus.
