 Pileum, cheeks, and chin glossy greenish black, with purplish reflections. Hinder part of

 than neck. Upper parts (except as described), under wing-coverts, axillars, and under tail- 

 coverts, glossy metallic dark purple, green, and bronze; the posterior portion of back, pos- 

 terior scapulars, wing-coverts, tertials, rump, upper tail-coverts, and tail nearly uniform 

 dull violet-purple, changing to bottle-green in certain lights; alula?, primary-coverts, pri-

Young (changing from first to second plumage): Head and neck distinctly streaked 

 with dusky brown and white, the dusky streaks wider and more blackish on the pileum, 

 the whitish streaks gradually becoming more indistinct below. Entire lower parts plain 

 snuff-brown, with a soft purplish tinge, especially on the breast and tibiae; crissum, metal- 

 lic green and violet. Upper parts dark, metallic violet-purple, green and bronze, the first

 but breast, abdomen, and tibise mostly reddish chestnut, and the anterior portion of the 

 back and scapulars mixed with many feathers of the same color; head and neck much 

 tinged with chestnut, the streaks indistinct (No. 17,493. female, Hungary). 



[Note. The Tantalus viridis of Gmelin (Syst. Nat. ii, pt. i, p. 648, No. 8, based on Green 

 Ibis of Latham, Synopsis, iii, pt. i, p. 114, No. 13) seems to be this species in incomplete first 

 plumage, or still retaining the downy covering of the head and neck.]

The young of P. autumnalis closely resembles that of P. guarauna, but is rather darker 

 colored, the upper parts being much more violaeeous. and the lower parts less grayish. 



The Glossy Ibis, like its white relative, is an irregular sum- 

 mer visitor to Illinois, and is not known to breed within our 

 limits. Mr. Julius Hurter, of St. Louis, Mo., took one speci- 



1 Audubon says: "Bill black; bare part of head grayish blue; iris hazel; feet grayish 

 black, claws brown."
