June, 1871 ; and it has also been found breeding at Lseso, on the Nordronner, on Bornholm, and 

 Christianso, on Hirtsholm and Dehlen, at Fredrikshavn, and on Hesselo. In the winter season 

 it is much more numerous than in the breeding-season, as large numbers arrive from the north 

 and remain to winter on the coast of Denmark. Professor Schlegel says he does not believe 

 that it has been met with on the coast of Holland for the last forty years ; but it is stated to 

 occur as a rare straggler on the coasts of Belgium in winter after severe weather ; and it occurs 

 irregularly on the coasts of France, chiefly in the northern districts : but, so far as I can ascertain, 

 it is unknown in Portugal, Spain, and the countries bordering the Mediterranean. I do not find 

 that the present species occurs on the northern coasts of Asia ; and if a Black Guillemot does 

 occur there, it appears to me that it will be found to be TJria mandti. 



On the American coasts it is very common on the Atlantic side of the continent, breeding 

 numerously in the north, and in winter found as far south as New Jersey. It is said to be rare 

 or accidental in the North Pacific ; but it would be interesting to examine specimens from there, 

 as I cannot but surmise that they would prove to be TJria mandti, and not true TJria grylle. 

 On the east coast it is found very far north ; and Captain Feilden, when on the recent Arctic 

 expedition, met with it up to 82° 27' N. lat. I am indebted to this gentleman for the following 

 notes, made by him during the expedition, viz.: — "On the 2nd of June 1875, as we left Bantry 

 Bay, a Black Guillemot flew across our bows ; and the next seen by us were a couple on the 4th 

 July 1875, in lat. 66° N. beyond Sukkertoppen, well up Davis Straits. On the 9th July 1875, 

 I found these birds breeding in great numbers on the small islands in Fortune Bay, Disco Island. 

 We shot several for an addition to our supper, and thought them very good. We also took 

 eleven eggs from the chinks of the rocks, and could have taken many more had we been provided 

 with any instrument to pull them out with. As in the British Isles, this species lays two eggs ; 

 and those that I procured showed no great variation in their markings. On the 24th July, in 

 passing through the middle pack, I observed but one Dovekie. On the 25th July, coasting along 

 the Crimson cliffs, we noticed several. They were nesting in the clefts of the rocks, where I 

 found Larus glaucus breeding on the Carey Islands ; and as I ascended several flew out. On the 

 27th and 28th July, as we passed Cape Alexander, Dovekies were numerous. When we lay at 

 Brevoort Island we noticed several Dovekies fishing in the pools of water between the broken 

 floes. On the 4th August, in Hayes Sound, I saw one. In the lofty Silurian conglomerate cliffs 

 of Washington-Irving Island many Dovekies were nesting, and they flew up and down to the 

 water in parties of six to a dozen ; their breeding-places were at an altitude of over three 

 hundred feet. Their note is a low plaintive whine, which they utter frequently as they swim 

 about fishing for entomostraca ; and they dive well when alarmed, and swim a considerable 

 distance under water before again rising to the surface. I shot here a specimen which showed 

 some variation in the amount of white on the scapulars. When walking under cliffs of great 

 altitude tenanted by Dovekies, we not unfiequently heard a rushing sound of wind, which some 

 of our people put down to sudden gusts of air. I satisfactorily assured myself that this was due 

 to the wings of the Dovekie ; for I watched the black specks leave the cliff, followed them with 

 my eye as they passed overhead accompanied by this peculiar sound, and saw them alight in the 

 water at my feet, when the sound ceased. August 14th, 1875. The Dovekies breed here at 

 Cape Hilgard, in the perpendicular limestone cliffs, at great altitudes, not less than eight
