XXXIII. — On a rare Species of Hawk, of the Genm 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 " Revue Generale 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 plus belle espece d'Accipitrien est sans contredit 

 celle que nous venous de retrouver dans le Musee d'Anvers, 

 sous le nom de F. pectoralis, Cuv. {Buteo pectoralis"^ Vieill.). 

 Quoique indiquee comme venant de I'Inde, 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. WolPs figure
