3. Notes on the Species of the Genus Asturina. By P. L. 
SciaterR, M.A., Ph.D., F.R.S., and Osperr Satvin, 
M.A., F.L.S. 
Recent investigations having convinced us that there is still much 
confusion amongst the American species of Hawks of the genus 
Asturina, we beg leave to submit to the Society the following notes 
upon the subject. 
The genus Asturina, founded by Vieillot in 1816 upon his Astu- 
rina cinerea (Falco nitidus, Lath.), embraces a small series of Ame- 
rican birds closely resembling Buteo in structure, but in habits more 
nearly approaching deccipiter. The most noticeable difference be- 
tween Asturina and Buteo consists in the shorter wings of the 
former; but in this respect Butevu pennsylvanicus (which has the 
habits of Asturina) is nearly intermediate between the two genera. 
Putting this bird aside for the present, we have left seven species of 
true Asturina, which may be separated into three groups, as fol- 
lows :— 
(1) The species allied to A. nitida, of which there appear to be 
two representative forms,—one occupying Central America and 
Mexico, which has been named A. plagiata; the other the true A. 
nitida, which, commencing its range at Panama, extends itself over 
the greater part of tropical South America. 
(2) The species allied to A. magnirostris, which is the type of 
the genus Rupornis of Kaup. These are four in number, each
