fifth, the fourth longest, the second much shorter than the fourth, which is longer than the 
third and fifth. In the European bird the second quill is longer than the fourth, the third 
longest of all. 
The first distinctive name for the common North American raven seems to be that of Bartram. 
The Q. cacalotl of Wagler, from Mexico, is probably a different species, as described further 
on. Prof. Agassiz named our bird C. lugubris in 1846,

the fourth quill is longest, then the third, fifth, second, sixth, and seventh. The first and eighth 
are about equal. The distances from the tip of the longest quill to that of the others is as 
follows :

lateral claw reaching to the base of the middle one.
