mode of nidification. I cannot discover from Dr. Malmgren's paper which form it is that inhabits 

 Bear Island ; and this is a point to which I hope future voyagers will pay attention. A great 

 many of the Dovekies seen about Spitzbergen have all the appearance of being barren birds ; and 

 these often have the tips of their secondaries weathered, a fact which led Lichtenstein and Brehm 

 to regard this accidental circumstance as a real character. Such specimens also generally have 

 dusky tips to the white feathers of the upper wing-coverts, and therefore seem to be birds of the 

 preceding year which have not fully moulted off their nestling-plumage." 



Von Heuglin, in his Notes on the Ornithology of Novaya Zemlya (J. f. O. 1872, p. 124), 

 says that he examined many specimens of Black Guillemots from there, and that all belong to 

 the present species and not to Uria grylle ; it appears, therefore, probable that TJria mandti is 

 found off the northern coasts of Russia. In Novaya Zemlya, he says, it breeds in July and 

 August in flocks under rocks on several of the islands, usually at no great altitude. The adult 

 birds are most industrious in supplying the young with food ; and he often saw them carrying fish 

 six and eight inches long in their bills to their breeding-places. They do not commence moulting 

 until the middle of September. 



In habits and mode of nidification the present species does not differ from Uria grylle. 



As the chief difference between the present species and Uria grylle is one difficult to show 

 on a plate, I have not deemed it advisable to figure Uria mandti. 



The specimens described are from Spitzbergen, and have been lent to me by Professor A. 

 Newton, of Cambridge. 



In the preparation of the above article I have examined the following specimens : —
