fifth, tlie fourth longest, the second much shorter than the fourth, whicli is longer than the 

 third and fifth. In the European hird the second quill is longer than the fourth, the third 

 longest of all. 



The first .listinctive name for the common North American raven seems to be that of Bartram. 

 The C. cacalotl of Wagler, from Mex'co, is probably a different species, as described further 

 on. Prof. Agassiz named our bird C. luguhria in 184C.

Colorado Raven. 



.'Coreuj cacalotl, Wagler, Isis, 1831, 527, Me.xico. 



Sp. Cb. — Win^ formula as in the other species. Length about 25 inches ; wing, 18 ; tail, 10.50. Tail much graduated ; outer 

 feather about 2.?0 inches shorter than the middle. Color glossy black, with violet reflections. Tarsus rather shorter than ths

Hah. — Coloraio river of California, (southward?) 



In this beautiful raven, which is very similar to the common species (the bill very much so), 

 the fourth quill is longest, then the third, fifth, second, sixth, and seventh. The first and ei|;hth 

 are about equal. The distances from the tip of the longest quill to that of the others is as 

 follows : 



The tail is rather long, and the feathers more graduated than in the other species, obtusely 

 acumiuattd, or mucronate, the outer 2.26 inches shorter than the middle. They are also 

 rather broader than in the other species. 



The feet are short and stout ; the tarsus a little longer than the middle toe and claw ; the 

 lateral claw reaching to the base of the middle one.
