HAWKS AND HAWKING. 287 
He would accordingly refer the typical members of the 
old so-called family Vultwride to the Falconide, and divide the 
diurnal birds of prey into the (1) Cathartide, American Vultures, 
(2) Gypaetide, which I should prefer to call Falconide, including 
the Falcons, Hawks, Eagles, and Old World Vultures, and (3) 
Gypogeranide (or as I would term it Serpentariide), to include 
the Secretary-bird. 
On the present occasion we have only to deal with the second 
of these families (which, as I have said, I should prefer to call 
Faleonide), and we may, therefore, dismiss the others at present 
from consideration. 
As regards the subdivision of this family into “ groups” or 
“subfamilies,” opinions differ, and it is unnecessary on the 
present occasion to discuss the various views which have been 
expressed. On this point the student may be referred to Professor 
Huxley’s paper, already mentioned; to Messrs. Sclater and 
Salvin’s “ Nomenclator Avium Neotropicalium”; Mr. Sharpe’s 
“Catalogue of the Accipitres in the British Museum,” with Mr. 
Gurney’s valuable comments thereon in ‘The Ibis’; Mr. Robert 
Ridgway’s outlines of a natural arrangement of the Falconide ; * 
and Professor Newton’s article on the genus Falco, in the 
‘Encyclopedia Britannica.’ 
For our present purpose it will be most convenient to adopt 
the subdivision employed by Mr. Sclater in his “List of the 
Vertebrated Animals ” in the gardens of this Society. This will 
obviate confusion, and will enable any visitor, with the “ List” in 
his hand, to apply the remarks I have to offer.
