436 Mr. Vlgors's Sketches in Ornithology. 



There are specimens of the male and female of this species irt 

 the collection; at least (hey agree in so many essential points 

 with the description of the type of the species, although they 

 differ in others, that I presume they must belong to it. The spe- 

 cies has indeed been observed to be extremely subject to varia- 

 tion. The chief difference in our birds is in the size, which is less 

 than that of the typical birds, and in the fascics of the wings and 

 tail, which are less frequent, and of a different form. Our female 

 is also much more rufous throughout. Wilson, in his American 

 Ornithology,* when describing F. Sparverius, refers to a smaller 

 Falcon found in the Southern States of North America, which is 

 nearly allied to that species, but at the same time distinct. I 

 suspect that the bird to which he alludes may be the following 

 species, which, although it has arrived in company with the birds 

 now described, I consider too strongly distinguished not to demand 

 a separate description.
