2. Colymbus holbcellii (Reinh.). HolbceWs Grebe. 



This Grebe is not common in any part of the territory. A single specimen was brought to me 

 from the Kuskokvim River, September 10, 187G, by Mr. J. W. Clark, who informed me that this 

 species was extremely rare in that locality. It frequents the lakes and tide lagoons. 



Two specimens were obtained at Unalashka Island. In this locality they are to be found only 

 in the winter season, and are not at all common. 



The iris is black ; bill, greenish-horn ; dusky on culmen and tomial edges ; tip of upper man- 

 dible, black ; lower, greenish ; feet, greenish with edges of scales darkened ; tips of toes dark ; in- 

 ner edges of lobes dark ; claws light-edged ; a male, No. 197, from Unalashka, December 17, 1878. 

 Another specimen, from the same locality, has the bill dark on base of culmen and region of 

 nostril, otherwise yellow ; feet greenish-yellow with darker lines through centers of scales, while 

 the scales themselves are edged with brilliant yellow. 



Several specimens of Grebes were observed among the Aleutian Islands, but it was beyond 

 my power to obtain them. The Eskimo name of this Grebe is Ta td title, from its note ta-ta-ta. 



3. Colymbus Aukitus Linn. Horned Grebe. 



This Grebe is occasionally seen in the neighborhood of Saint Michael's; more often in spring 

 or fall. In the interior of the Yukon District it is common, especially along the tributaries of the 

 Yukou. At Nnlato and Fort Yukon it is said to breed ; although, I do not think it does along the 

 coast in the vicinity of Saint Michael's. 



Among the Aleutian Islands it is to be found in the winter. I did not observe it there in the 

 summer and at no time to the westward of Unalashka Island. 



This species prefers the fresh bodies of water, and only resorts to the bays and estuaries when 

 the fresh water is frozen. The nesting habits of this species were not learned by me. 



The iris of the species is yellow, culmen black, rest of bill bright yellow, outer side of tarsus 

 and under side of web blackish ; inner side of tarsus, toes, and lobes bright yellow, with faint 

 greenish tinge ; claws dark. 



The native who brought me a specimen of this bird had no name for it, and declared it was 

 the first he had seen. 



At Attu Island I observed a Grebe, which I suspected was this species. It was so shy that 

 near approach was impossible. 



7. Urinator imber (Gunn.). Loon. 



This Loon occurs but sparingly, according to my own experience, along the Alaskan shores. I 

 saw three individuals at once in the vicinity of Cape Newenham, and occasionally an individual in 

 the vicinity of Saint Michael's. I failed to secure specimens of it for preservation. 



8. Urinator adamsii (Gray). Yellow-UUed Loon. 

 This Loon occurs sparingly in the vicinity of Saint Michael's. 



The only specimen seen by me, that I could certainly identify as this species, was killed by a 

 native. A press of other work caused me to delay preparing the skin until it was too late.
