Hab. Mexico to South America. Accidental in the United States. (New Jersey, 

 Kentucky, and Mississippi, Audubon.) 



This species claims a place in the fauna of the United States on account 

 of two specimens captured in New Jersey, at long intervals, and one or two 

 seen by Mr. Audubon in the southwest. It is, however, hardly proper to 

 include it in our work on so slight a basis, and we only retain it for the 

 purpose of referring to the notice of it by Mr. Audubon. 



Habits. The Fork-tailed Flycatcher is of purely accidental occurrence in 

 the United States. Two specimens, taken at long intervals, are said to have 

 been captured in the United States. One of these was shot by Mr. Au- 

 dubon, in June, 1832, near the city of Camden, N. J. It was first observed 



' 31. tyranmis, var. violent>is {Tyrannus violenlus, ViEiLL. N. D. xxxv, p. 89. Milvulus 

 v., ScL. Catal. Am. B. 1862, 237), is the South American race of this species. It is exceedingly 

 similar, but differs slightly, though constantly, in certain characters. "We have not at present 

 the means of comparing the two.
