 melanogenys, from Australia and Java. Var. anatum, generally distributed in America. 

 Var. minor from South Africa.

Without feeling at all assured of even varietal distinctions in this case (excepting 

 var. minor). I arrange the synonymy as above. The several sets of names may be 

 readily combined if desired, while it would be less ea.sy to separate them if the 

 synonymy were compiled indiscriminately. I quote several names, for the identifica- 

 tion of which I am not responsible, on the authorities cited in the respective cases. 



The American Duck Hawk appears to ha\'e been first separated from the Old World 

 Peregrine by Prince Bonaparte, in 1636 ; but no characters were, to my knowledge, 

 then ascribed to it, and it is very doubtful that any exist. It may be presumed 

 that this author was misled by a then supposed, but since proved groundless, differ- 

 ence in the nidificatiou ; more likely, however, he proceeded upon some theory respect- 

 ing geographical distribution. The name has, however, been very generally adopted, 

 even by those who have demurred against it. One of the highest authorities on birds 

 of prey, Dr. Schlegel, states, after e.xamination of various examples from North and 

 South America and Mexico, that " le Faucon commun de I'Am^rique ne difffere en au- 

 cnne fagon du notre." Such is nearlj' my own view ; and even Bonaparte, in 1650, 

 confesses that his anatum is " forsan a F. commmii spec, hand diversus." Mr. Ridgway, 

 however, claims good varietal characters for our bird A later candidate for recogni- 

 tion is found in the F. nigriceps of Cassin, which, like F. anatum, rests upon some 

 ascribed characters, beiog said to be smaller, darker, &c. But these features appear 

 to be fortuitous, belonging to the category of individual peculiarities ; and since pure 

 anatum has been determined to occur within areas supposed to be occupied by nigriceps, 

 even its character as a geographical race disappears. Of the Australian F. melanogenys. 

 Dr. Schlegel has remarked : " La variety accidentelle fonc€e de I'Australie » » » « 

 ne mferite pas mSme le nom de conspecies."
