XXXIII.— On a rare Species of Hawk, of the Genus Accipiter, 
from South America . By P. L. Sclater. 
(Plate X.) 
The accompanying illustration is a reduction from an original 
water-colour drawing by Mr. Wolf, belonging to Mr. J. H. 
Gurney's portfolio, and represents a little-known species of 
Hawk, of the genus Accipiter, which I propose to call Accipiter 
pectoralis. This scarce bird has never been properly described, 
but has been alluded to by Prince Bonaparte, in an article en¬ 
titled u Revue Generate de la Classe des Oiseaux," in the ‘ Revue 
et Magasin de Zoologie' for 1850 (p. 474 et seq .), in the fol¬ 
lowing terms:— 
“ Mais la pins belle espece d'Accipitrien est sans contredit 
celle que nous venons de retrouver dans le Musee d'Anvers, 
sous le nom de F. pectoralis, Cuv. ( Buteo pectoralis ? Vieill.). 
Quoique indiquee comme venant de PInde, elle vient du Bresil, 
et rappelle, par son plumage, le Spizaetus ornatus. Sa taille est 
celle de mon Astur cooperi; le dessus de la tete et le dos sont 
noirs; la gorge blanche; le haut du cou et la poitrine d'un roux 
pur; le ventre blanc, barre de taches noires; la queue cendree, 
traversee de quatre bandes noires." 
Besides the example in the Museum of Antwerp thus spoken 
of by Prince Bonaparte, the only specimens of this Hawk which, 
as far as I know, exist in European collections, are in the Derby 
Museum at Liverpool. From one of them Mr. Wolfs figure 
VOL. in.
