The Blaek-tliroated tJuilleiiiot is aiiotlior of tlie strikingly jji'diliar forms of dci'])- 

 sca-goiiig birds found exclusively in the I'acitic Ocean, visiting tlie islands and the 

 coasts of both the American and the Asiatic mainland. They occur with some irregu- 

 larity in their distribution, and being probably, like most of their family, of nocturnal 

 habits, wo know but little of their sj)ecitic iieoidiarities of numner. They are found 

 as far south as Jaiian, and as far north as Sitka and the Island of Anuik. 



Several si)ecimens were taken by ]\Ir. ]I. A\'l)itely in Hakodadi Harbor, Japan, iu 

 May. !Most of them had lost either their riglit or their left foot ; these had been 

 apparently bitten off some time previously, as the place M'as healed and the skin 

 grown over it. Mr. lUakiston speaks of it as common in the game market of Yoko- 

 luuna in winter, and Swiidioe found it common in Yezo from October to Maj'. 



Jlr. Dall states that this species, called by the Kussians '• Starik," is common at 

 St. George's, and also at Amak Islan<l, north of the peninsula of Aliaska. Speci- 

 nu>ns were also obtained at Sitka by liischoff. 



In his Notes on the Avifauna of the Aleutian Islands, lying east of Unalashka, 

 Mr. Dall states that this si)ecies was obtained breeding, with the eggs, at the Chica 

 Islets, Akutau Pass, near rnalashka, Juiu' 2. 1S71.'. They were caught sitting on 

 their nests, which are in holes in the bank, similar to those of the Tetrels — Omino- 

 (IroiiKi fnrratd. There were two eggs in each nest, and in several cases the male 

 bird was sitting on the eggs. lie did not meet with this species in any other place, 

 yet it may be abundant, notwitlistauding. 



Afterward, in his Notes on the liirds of the Islands west of Unalashka, Mr. Dall 

 speaks of iiiuling it abundant throughout the islands, especially in certain localities. 

 He ol)tained it from Kyska eastward. While it congregates off shore in ver}' great 

 nund)ers, it also frec^uents the bays and harl)ors much more than any of the other 

 small Auks. The iris of this bird is white. 



Anu)ng other spccinu'us of the young form, Mr. Dall olitained one at Anichitka 

 with a malformation of the lower mandible, which was nearly one half shorter than 

 the ujiper one. The bird was fat and healthy. 



Specinu'us of the eggs of this species are iu the Smithsonian collection, obtained 

 from Cliico Island, Sitka, and Aliaska. Their ground-color is a pale buff; over this 

 are very generally and ecpially distributed small longitudinal nuxrkings, somewhat 

 subdued, of lavender-gray and a light brown. Four eggs measure as follows : 2.15 

 by 1.45 inches ; 2.35 by 1.55 ; 2.45 by 1.55 ; 2.50 by 1.40.
