The Astur approximans has been with propriety removed to the genus Accipiter by Mr. G. R. Gray, and to this genus my A. cruentus is also referable; for although of a larger size than the other members of that form, their structure, except in the shorter middle toe, is very similar.

This species and the preceding are representatives of each other in the eastern and western portions of the continent.
