ORNITHOLOGICAL EXPtOEATIONS. 



Ou Bering Island it is only an occasional visitor, being chiefly an in- 

 land bird preferring the quiet rivers and lakes surrounded by dense 

 forests. During my sojourn ou the islands two individuals were re- 

 ported as seen, one early in the spring, the other about the 8th of June, 

 ]883. A specimen obtained by Mr. Grebnitski the year previous to my 

 arrival was examined by me, and the measurements are embodied in 



the following — 



Taile of dimensions. 



No. 92732.— Tail beyond clo.'sed wings, 120™"; stretch of wings, 2.220". Iris, cream color. Bills, 

 cere, and naked eye-space, as also the feet, intense golden yellow, bill tending to orange, and without 

 trace of dusky. Testes small. Not fat. 



No. 92733.— Tail beyond closed wings, 115""" ; stretch of wings, 2.250"". Iris pale cream color. Bill, 

 cere, and naked eye-space orange yellow, slightly dusky at tip of upper mandible. Feet yellow, tarsus 

 somewhat paler ; claws horny, bluish gray. Testes small, not swollen. Not fat. Weight, 12 pounds. 



No. 92731.— Tail beyond closed wings. IIO"" ; stretch of wings, 2 360™. Iris, yellowish cream color. 

 Bill, cere, and naked space of face yellow, the bill somewhat tinged wilh orange. Feet bright golden 

 yeUow; claws horny whitish, blackish only along the back. A naked "breeding patch," 140 by 90""", 

 on the anterior part of the belly. Ova very small, only a few being swollen, and measuring about 5"'°'. 

 Rather fat. 



A most interesting specimen is No. 92738, a downy young, just as- 

 suming the first i)lumage, the feathers coming out copiously on head, 

 upper neck, interscapular region, wings, breast, anal region, and tail. 

 The i^redominant color of the feathers is a dull blackish brown, slightly 

 lighter brownish on the middle of the feathers of the top of the head; 

 the inner webs of the wing-coverts are lighter, some at the base whit- 

 ish, secondaries and scapulars margined with lighter brown. The tail- 

 feathers, of which only the tips are visible, are white near the end, mot- 

 tled with blackish further up. Tiie down covering the rest of the body
