Adult male. Similar to P. falcinellus, but distinguished by the 

 reddish lores and reddish base of chin (these parts being lake-red in 

 life), and by the white facial band, which forms a sort of mask 

 across the forehead, round the eye, and along the fore part of the 

 cheeks and across the chin : " bill dusky, sometimes tinged with 

 reddish ; lores, eyelids, and naked skin of chin lake-red or pale 

 carmine ; legs and feet varying from greyish brown to deep lake- 

 red : iris crimson " {Ridgwai/). Total length 21 inches, culmeu 5-4, 

 wing 10-7, tail 3-6, tarsus 4-1. 



Adult female. Similar to the male, but smaller, and with a shorter 

 bill. Total length 20 inches, culmen 4-1, wing 9-8, tail 3-7, 

 tarsus 3" 2. 



Wluter plumage and young plumage are exactly analogous to 

 those of Plegadis falcinellus. The young birds are uniform green 

 above, with very short bills, and the commencement of the finer 

 plumage is noticeable in several examples from Southern Brazil, 

 procured in the winter habitat of the species. The wing-coverts, 

 as pointed out by Mr. Ridgway, have no chestnut in the immature 

 birds, and the bill is " pale greenish horn-blue, blackish terminally 

 and duskv basally ; legs and feet deep black ; iris hazel." 



Hah. Southern United States and Mexico, to Oregon on the west 

 coast, to Texas and the St. John's liiver in Florida on the east ; 

 Southern Brazil, Chili, and Patagonia ; St. Domingo, and Sandwich 

 Islands.
