based upon the descriptions in Lewis and Clark's narrative. As may be 

 supposed, many of the birds which were entertd 'on the authority of 

 Turton (or Gmelin) were wrongly attributed to North America, some 

 being European and some South American. Quite a number of other 

 names, originally proposed by Gmelin, are entirely unrecognizable. 



Gmelin 's edition of the System a Naturae of Linnaeus is the one most 

 frequently referred to in the following notes. Ord's references to Lewis 

 and Clark are to be found in the edition of Nicohlas Diddle published 

 in Philadelphia in 1814.

 GENUS VULTUR. 



Besides the three species of Vultures which inhabit the United States, 

 three others appear in the list, of these the Condor and King Vulture 

 are South American, the latter reaching southern Mexico. 



Vultur columbianus is a new name of Ord's based upon the "Buzzard" of 

 Lewis and Clark. It is a synonym of the Vultur californianus immed- 

 iately preceding, =Pseudogryphus calif ornianus.
