Hah. Cuba (Gundlach) ; North-eastern coast of South America 

 to the mouths of the Amazon ; Florida (Aud.), accidental. 



If this species has been met with on the continent of North 

 America, it is probable that it has only accidentally strayed there 

 from its usual haunts, as it is properly an inhabitant of North- 

 eastern South America, its appearance even in the West Indies, 

 we may suppose, being uncertain and made at irregular intervals. As 

 the genus Ibis was formed by Savigny for the J. cethiopica (Lath.), 

 or Sacred Ibis, it cannot be retained for this bird and its allies, as has 

 been generally done ; and as Eudocimus of Wagler comes next, that 

 must be the term employed. As there is no rule by which Moehring's 

 genera can be received, and so many of them are rejected even by 

 those who cite his works, it is not allowable that his term Ibis, insti- 

 tuted for this species, should take precedence of that of Savigny. 



Entire plumage bright red, with the tips of the primaries jet- 

 black for about two inches. Forehead, face, and throat bare, feathers 

 coming forward anterior to the eye on top of head ; bare space of 

 throat and face red. Bill red, tip blackish. Legs and feet red. 



Total length 25 inches ; wing 10, tail 4|, bill along culmen 4^.

Genus Aulacoscelis, Chevrol. 



1. Aulacoscelis melanocephalxjs, sp. nov. 



Elongate, subovate, widened behind ; head and thorax shining 

 black ; epistome separated from the face by a deep transverse 

 groove ; antennae entirely black, similar in length and shape to A. 

 melanocera, Stil. Head smooth, shining, with a few scattered
