The ^' Tschornij Ghipisch^^ is rather scarce on the islands, although I 

 feel convinced that a few breed there. I saw a small flock on the 22d 

 of August, 1882, at the entrance of Lissonkovaja Buchta, southern part 

 of Bering Island, leaving the whale carcass upon which they were sit- 

 ting at our approach. A specimen was obtained on Copper Island in 

 June, 1883. It had been captured bj- one of the natives on the 17th of 

 June, skinned and dried flesh side out, awaiting my arrival. I made 

 afterwards a tolerably satisfactory (considering the circumstances) skin 

 out of it. Its dimensions are:

Another specimen of the Slender-billed Shearwater was secured on 

 Bering Island by one of the natives and prepared hy him for Dr. Dy- 

 bowski, in 1882, before mj' arrival to the islands. Eemarkablj" enough, 

 neither Taczanowski nor Dybowski have mentioned the species in their 

 recent catalogues of birds from that region. I had the opportunity of 

 examining the specimen and made the following notes: 



Chord of culmcn 34™'". Commissure 49™™. From autcrior border of nostrils to tip 

 of maxilla 24™™. From malar apex to tip of mandible :32™™. Heif,dit of bill in front 

 of nostrils 7.5™"\ Tarsus 54™™. Middle toe Avith claw 63'"™. Wing 290™™. Tail-feath- 

 ers 92™™. Graduation of tail 2r""\ Upper surface dark sooty brown, almost black on 

 wing and tail feathers, lighter and more grayish below. Chin and upper throat almost 

 whitish gray. Feet (in the dried specimen) on the outer side dark brownish, pale on 

 the inner side, almost black below. 



The specimen obtained by me is similarly colored but the chin and 

 throat are not so light.
