 ries, tlie middki tail-l'oathers, and tiie grisater coverts. The long primaries 

 and ten tail-feathers, however, are of full Ittnglh. It is possible that the 

 bird is really as large as the northern Crow, although this is hardly probalile. 

 it was killed on the mainland of the extreme southern i)ortion of Florida, 

 not far from Fort Dallas. 



No comparison of this binl is rei|nired with the Fish Crow, which has the 

 middle too ivnd claw longer than the tarsus, not shorter, and the proportions 

 much less. 



H.vtilTS. The connnon resident Crow of Fhirida exhibits so many pecu- 

 liarities differing from tiie northern species, that Professor Baird, in his 

 Jiirds of America, deemed it worthy of mention at least as a race, if not a 

 distinct species. We have no account of its habits, and do not know if, 

 in any resjiects, they differ from those of the common Crow. Dr. J. C. 

 Cooper, in his brief manuscrij>t notes on the birds of Florida, made in the 

 spring of 185!), s})eaks of the Florida Crow as very common, as being (piite 

 maritime in its haiiits, and as having full-fledged young on the 2(lth of 

 April. Three eggs of this race, obtained in Florida in the spring of 1871, 

 by Mr. ^layuard, differ not more from tho.se of the Crow than do those of the 

 latter occasionally from one another. Tliey measure 1.7.'5 by 1.20 inches ; 

 1.7<) by 1.20 ; and 1.54 by 1.25. Their ground-color is a bright bluish-green, 

 and they are all more or less marked, over the entire egg, with lilotches of a 

 mingled bronze and brown with viohit shadings. The latter tints are mort! 

 marked in one egg than in the others, and in this the sjiots are fewer and 

 more Jit one end, the larger end being nearly free from markings. Their 

 average capa ty, as compared Avitli the average of the 0. uincricaiiu^i, is as 

 5.1 to 4.2.
