 bracharhynchus and L. calif amicus), the secondaries passing into white terminally. Primaries paler 

 pearl-blue, the five outer quills with their terminal portion black, this color extending for about 

 3.25 inches on the outer and .75 of an inch, more or less, on the fifth, and of intermediate extent on 

 those between ; outer web of the exterior quill almost wholly black ; inner quills pah- pearl-blue,

 and immediately in front of the eye, with a 

 dark plumbeous suffusion, sometimes extending 

 across the occiput. Young, first /damage : Some- 

 what similar to the winter adult, but lower 

 part of nape covered by a large transverse patch 

 of black, the anterior lesser wing-covert- also 

 more or less black, as are the centres of the inner 

 longer coverts and tertials ; primary coverts and 

 outer webs of four or five outer primaries also 

 black. Tail crossed at the end (except lateral 

 pair of feathers) by a broad black band, widest 

 on the intermedia;. Eill wholly black ; " edge

The Common Kittiwake is a northern species, found both in Europe and America, 

 in the waters of the Atlantic, and represented on the Pacific by an allied form so 

 essentially similar to it that the two cannot be specifically distinguished from each 

 other. It is more or less abundant in the northern portions of Asia and Europe, 

 and occurs on both the eastern and western shores of North America in northern 

 latitudes. During the winter it wanders south in an Irregular manner. 



Mr. Godnian met with a few individuals about the harbor of Punta Delgada, in 

 the Azores, on his arrival there, and was informed by the master of one of the fruit 

 schooners that these birds frequently followed his vessel through the whole of the 

 voyage from England. Mr. Godman was led to believe that this species breeds about 

 the coast of Teneriffe. He is confident that he saw either this bird or L. canus 

 at Teneriffe in the middle of May, but he was not able to secure any specimens. 

 Mr. Saunders found the Kittiwake abundant on the outside of the Straits of Gibraltar 

 in the winter, but it was more rare to the eastward. 



The Kittiwake is given by Middendorff as a bird of Siberia, where it extends its 

 movements to the farthest north. Mr. Gillett mentions his having found it common 

 along the entire coast of Nova Zembla. Von Heuglin found it one of the most com- 

 mon species on tbe west coast of Nova Zembla. It was not seen in Matthews' Strait, 

 nor on 'Waigatsch Island.
