Sp. Ch. — Mult. Entirely white ; tail and quills metallic blackish green, with purple reflections. 
Young. Neck and head feathered as in Ibis. Color duller than in adult ; the downy feathers of neck dusky. 
Length about 45 inches ; wing, 18.50 ; bill, 8.50 ; tarsus, 7.10. 
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.

IBIS, Moehring. 
Ibis, Moehring, Genera Avinm, 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 the end of the bill. Nostrils impervious, surrounded, except below, by membrane. Basal portion of cutting 
edges of bill with dull serrations in one species. Forehead and base of bill all round, extending behind the eyes and on the 
chin, bare, except in I. ordii. Tibia bare for half its length, covered with hexagonal scales ; scales on the anterior part of 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 Seba, 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 
and red bill of the second, and the chestnut body and neck with metallic green, &c, on the
