194:. Colymbus Adamsii Gray. (YOla.) Adams' Diver. Kadiak 
195, I'odice2>s griseigena Gray. (702.) Red-necked Grebe. Not 
uncommon at St. Michael's, and on the marshes on the river up to Fort 
Yukon, where Mr. Kennicott obtained the eggs. Bischoff also collected 
190, Podiceps cormttus Lath, (706.) Horned Grebe. Killed a 
number of this species at Nulato, May 25th and 26th, 1868. Not very 
common. The ball of the eye is white, with a bright scarlet areola 
around the outer edge of the iris, which is defined by a white line. The 
iris proper is bright crimson. The inner edge is brilliant white, with a 
shade of pink in it ; and the pupil within consists of a broad ring of dark 
purple, with a central spot of black, producing a most brilliant effect. 
This was a female, with one egg well developed in the ovary. Bought 
a parent and two eggs of an Indian at Fort Yukon, in June, 1867. D. 
197, Mormon cirrhata Bon. (712.) Tufted Puffin. Not very 
common at St. Michael's. Abundant on Besborough Island. Plentifully 
obtained by Bischoff at Sitka and Kadiak. D. 
At St. Michael's, though by no means scarce in the same situations, 
the Tufted Puffin is very much less abundant than the M. corniculata 
— at least five or six of the latter may be seen to one of the former. 
The tufts of this species are indicative of maturity, young individuals, 
although otherwise nearly fully fledged and able to fly, having these but 
very imperfectly developed. 
Both this and the other species are used as food by the Eskimos, and 
their tough and thickly plumaged skins are, together with the skins of 
loons, etc., made into winter dresses by the Magemuts and Southern 
Unaleets. B. 
198. Mormon corniculata Naum. (713.) Horned Puffin. Ex- 
tremely common on the rocky islets near St. Michael's. Observed by 
me at Plover Bay, Coal Harbor, Ounga Island, and Aliaska. Has been 
obtained at Kotzebue Sound, and was abundantly received from Sitka 
and Kadiak through Bischoff. D. 
Abundant on Whale Island north of the harbor. The island is steep 
and rocky, and difficult to land upon, except in very favorable weather. 
Upon the only occasion on which it was visited no nests were discovered, 
though I am confident that both this species and M. cirrhata breed 
there, and young birds, scarcely able to fly, have been captured. The 
reason of the nests not being seen is due to the structure of tlie island. 
The birds nest in the deep and narrow joints, and interstices of the rock, 
generally entirely out of reach of any thing except blasting powder. 
Even if the nest was within reach of a man's arm, it would be hazardous 
to attempt to rob it without full assurance of the absence of the parent 
bird, which, with its powerful bill, and the advantages of its situation,
