eiglit. The outer lateral toe is shorter, not reaching the base of the middle claw. The middle 

 toe and claw are considerably shorter than the tarsus ; the middle claw is shorter than in the 

 northern bird. 



The wings formula differs somewhat ; the third, fourth, and fifth quills are nearly equal, the 

 third even longer than the fifth instead of shorter. The tail is short and very nearly even, the 

 difference in length of feathers being less than half an inch instead of an inch. This, however, 

 may in part be owing to the absence of the middle pair. 



The colors differ somewhat from those of the common crow. There is less violet, and the 

 feathers of the back have almost a brassy gloss on their margins, as in (Jrotopkaga. 



The specimen upon which these remarks are based, though apparently perfectly mature, is 

 changing some of its feathers, such as the inner primaries, the middle tail feathers, and the greater 

 coverts. The long primaries and ten tail feathers, however^ are of full length. It is possible 

 that the bird is really as large as the northern crow, although this is hardly probable. It was 

 killed on the main land of the extreme southern portion of Florida, not far from Fort Dallas. 



No comparison of this bird is required with the fish crow, which has the middle toe and claw 

 longer than the tarsus, not shorter, and the proportions much less. It is much larger than the 

 curious little Corvus minutus of Cuba, a specimen of which has been supplied by Mr. Lawrence. 

 The Corvus minutus^ is, of course, still smaller than the G. americanus, the bill stouter at the 

 base ; the third, fourth, and fifth quills nearly equal and longest. The chin is more bristly, 

 the feathers of the throat more distinctly defined. Although about the size of the fisti crow, it 

 has much stouter bill and legs, and the tarsus is much longer than middle toe and claw, not 

 shorter. The Corvus minutus and var. floridanus are more nearly allied in every respect than 

 either is to C. americanus. Their measurement will be found in the accompanying table, the 

 first specimen referring to the Florida bird, the second to the minutus. 



Bar tram, in his list of North American birds, (Travels in Florida,) mentions a "Corvus 



maritimus, Great Seaside Crow," but without specifying locality or giving any description. If 



a Florida bird, it quite probably refers to the present species, which is doubtless quite maritime 



in its habits. i
