5. The South- Brazilian Subregion. 



The South-Brazilian Subregion contains the whole of the 

 vast forest-area which occupies the coast-land and adjacent 

 interior of Southern Brazil from the watershed of the Rio 

 San Francisco down to the open prairies of the Rio Grande 

 do Sul, whence Dr. H. von Jhering has recently sent us a 

 very interesting account of the avifauna of its southern 

 limits (116). How far the limits of this subregion should be 

 properly extended into the interior it is not possible to settle 

 accurately until we have a better knowledge of the avifauna 

 of Inner Brazil. 



In the South-Brazilian Subregion we have frequent cases 

 of the replacement of Amazonian species by allied but 

 distinct forms. But besides that we also find certain generic 

 types entirely restricted to this subregion. Amongst these I 

 may specify Cypsnagra and Pyrrhocoma among theTanagers, 

 Tijuca, Phibalura, and Calyptura among the Cotingas, and 

 Jamaralcyon among the Jacamars as evidences of this fact. 



The standard works of Prince Max. of Neu-Wied, Bur- 

 meister, and Reinhardt, and others referred to in my " British 

 Association Address/^ still remain our leading authorities 

 on the birds of the South-Brazilian Subregion, and a more 

 modern handbook on the subject is now much required. I 

 could well wish that my excellent friend Count von Berlepsch 

 would undertake this piece of work, for which he is specially 

 qualified by excellent contributions already made to it (117- 

 119) and by his possession of an extensive series of Brazilian 

 birdskins. As regards the Brazilians themselves, it seems 

 that there is little hope of any native talent being attracted 

 to this subject. 



6. The Patagonian Subregion. 

 Mr. W. H. Hudson, C.M.Z.S., when resident in Buenos 

 Ayres, maae large collections of birds, which he forwarded to 

 England and the United States, and accumulated a series of 

 valuable notes, some of which were published from time to 

 time in the ' Proceedings ' of the Zoological Society of 

 London. After Mr. Hudson had settled in this country I
