Subsequent editions appeared in 1671 (London) and 



1677 (Oxford) the title in the last case being altered to 



" Gualteri Charletoni Exercitationes &ct." 



Commencing with the land-birds, Charleton deals 

 first with the " Carnivora " as he terms the Rap tores. 

 He gives us a long and somewhat confused list of the 

 eagles, vultures, falcons, and hawks, among which may 



be mentioned " Peregrinus the blewbackt 



Falcon, preying chiefly upon Herons," and informs us 

 that it was named Peregrinus because it was always 

 moving from one district to another, or because its nest 

 could nowhere be discovered.* 



" Gyrfalco, the Gyrfalcon, frequent in Ireland." 

 Among the Corvidse he notices the " Cornish Chough," 

 which he tells us is abundant in Cornwall, and is there 

 called the " Killigrew " (c/. Swainson, Provincial Names 

 of British Birds, p. 74). 



Amongst other birds mentioned are " Loxia the Cross- 

 beak or Shellaple," which he informs us is found in 

 England from time to time. 



* There is nothing remarkable in Charleton's ignorance of hawks 

 and falcons ; long after his time we find that this subject was a constant 

 source of error and confusion to our Ornithologists, a confusion which 

 arose in part as Thomas Pennant {British Zoology, 4th Ed., Vol. I., 

 p. 183) informs us from the fact that the various writers on natural 

 history chose to adopt as distinct varieties the several different 

 names used by the falconers to describe one species at various periods 

 of its life.
