COllVUS LEPTONYX. 513 



CORVUS LEPTONYX, Peale. 



[The discovery that Corvus corax is replaced in Barbarv by a very distinct species 

 is undoubtedly due to Colonel Irby (Ibis, 1874, pp. 264-266), vi^ho described it as 

 C. tingitanus ; but it has since been found that he was anticipated in giving it a 

 name by Mr. Peale, the ornithologist of Commodore Wilkes's squadron, who, in 

 1848, described and figured as C. leptonyx (U.S. Expl. Exped. viii. p. lOo, pi. xxix.) 

 a Raven which he had shot near Funchal, and it is now admitted that the Raven 

 of Madeira is specifically identical with that of Mauritania. Had Mr. Wolley 

 preserved the specimen he obtained at Tangier in 1845, its distinctness from the 

 European bird might have then been recognized. At that time he could have had 

 very little experience of Ravens, though, as will appear, he was the possessor of a 

 tame one.] 



\ 2760. 0;?e.— Tangier. From Mons. Favier, 1847. 



Bought, with others, of Mr. Williams, of Oxford Street [§ 2]. It 

 bears M. Favier's label '^Corvus corax." If so, it is a small specimen. 

 Ravens were abundant at Tangier in 1845, when I shot one.
