Bill light greenisli yellow ; eyelids, commissure, and iuside of mouth 

 deep orauge red ; legs and feet black. 



The feet of two individuals shot at Cape Lisburne are preserved in 

 alcohol. There is a well-developed nail on the hind toe of one of these 

 feet, while the rest of the nails are quite rudimentary. The pair of feet 

 havingthebest developed nails had, when fresh, a mere trace of yellowish 

 on the skin of the under surface of the toes, while the other pair had 

 bright yellow areas on the corresponding parts. 



The young female shot at St. Mathew Island was in the nest. The 

 nests were built of sea-weeds on high, narrow ledges of the inaccessible 

 cliff's. Abundant in this locality with Fratercula corniculata and Ftil- 

 marus glaciaUs Rodgersi. At St. Mathew Island we saw a great many 

 beautiful young kittiwakes flying near Cape Upright, the black collars 

 and wing j)atches making them attractive objects of pursuit.

 Common. 



65. Larus marinus Linn. 



81694 (3841) juv. head. Chernoffsky, Unalashka, Oct. 1, 1880. 



Abundant, feeding at the mouth of the river falling into the head of 

 Chernoff'sky Bay. The first recorded instance of its occurrence on the 

 west coast of America. 



66. Stercorarius pomatorhinus (Temm.) Viell. 



(3738) sternum. Point Belcher, Aug. 27, 1880.

81702 (3672) head in alcohol. Point Belcher, Aug. 27, 1880. 



The eggs of this bird (81427) were very small. The species was very 

 common, with Kyctea scandiaca, on the rising ground, industriously feed- 

 ing upon something which I could not make out because of the diffi- 

 culty of approaching the birds. The flights of this jjeger from sea- 

 ward to the land and back again were frequent. We found Stercorarius 

 very abundant in the vicinity of the whaling shij^s, where it fared sump- 

 tuously.
