THE NEOTROPICAL REGION.

distribution we can find recorded is that of the genus of ducks, 
Cam'ptolmmm, 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 Kio 
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 
Cunninaham, and other sources ; and will be useful for com- 
parison.
