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.

18. Astur cruentus, GouldVol. I. Pl. [18].

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

I have lately seen specimens from Port Essington.

Genus Accipiter, Briss.

19. Accipiter torquatusVol. I. Pl. [19].

Precisely similar in all its actions and in its economy to the Sparrow Hawk, Accipiter nisus of Europe.
