THE NEOTROPICAL REGION. 



39 



distribution we can find recorded is that of the genus of ducks, 

 Gamytolcemus, which has a species on the east side of North Ame- 

 rica and another in Chili and the Falkland Islands, but these, 

 Professor Newton assures me, do not properly belong to the same 

 genus. Out of 30 genera of land-birds collected on the Eio 

 Negro in Patagonia, by Mr. Hudson, only four extend beyond the 

 American continent, and the same exclusively American character 

 applies equally to its southern extremity. No list appears to 

 have been yet published of the land-birds of the Straits of 

 Magellan and Tierra del Fuego. The following is compiled from 

 the observations of Mr. Darwin, the recent voyage of Professor 

 Cunningham, and other sources ; and will be useful for com- 

 parison.
