Hab, — South Atlantic and Gulf States, and across to the Colorado river; as far north as North Carolina and mouth of Ohio. 



This well known species needs no especial comparisons to distinguish it from every other 

 North American hird. It is said to be abundant on the Colorado river, especially about Fort 

 Yuma, and to be there called Colorado turkey. 



List of specimens. 



IBIS, Moehring. 



Ibis, Moehring, Genera Avium, 1758, 71. Type Tantalus ruber, L., according to G. R. Gray. 



Ch. — Bill very long, moderately thickened at the base, and curving downwards to the tip. Nasal groove deeply impressed, 

 extending to tlie end of the bill. Nostrils impervious, surrounded, except below, by membrane. Basal portion of cutting 

 edges of bill witli dull serrations in one species. Forehead and base of bill all round, extending behind the eyes and on the

 tarsus broad and transverse. Middle toe nearly as long as the tarsus ; outer lateral longer ; hinder elevated ; toes connected at 

 base by web . 



Gray gives Tantalus ruber, L., as the type of Moehring's genus Ibis. This author quotes 

 Belon. 1. 4, c. 9, and Seha, Thesaurus, I, tab. 62, f. 3. The latter citation is said to refer to 

 Tantalus ruber ; of the former I can learn nothing. 



The North American species are readily known by the red color of the first, the white body 

 S.nd red bill of the second, and the chestnut body and neck with metallic green, &c., on the
