2. ' The Auk.' 



[The Auk. A Quarterly Journal of Oruithology. Vol. xvii. Nos. 3 

 and 4, July and October 1900.] 



The first paper in the July number of ' The Auk ' is by 

 Mr, H. W. Henshaw, on the "Occurrence of Larus glaucescens 

 and other American Birds in Hawaii'^ ; but inasmuch as the 

 writer persistently speaks of certain Gulls by the trivial name 

 of " Glaucous Gull/' we are unable to recoguise the exact 

 species to which he refers, for Larus glaucescens and L. glaucus 

 are perfectly distinct. We expected to find a correction or 

 explanation of this error in the October number^ but see 

 none. The remaining birds identified in the Hawaiian grou[) 

 are Diomedea chinensis, Mergus serrator, Crymophilus fuli- 

 carius, Calidris arenaria, and Gallinago delicata, while other 

 migratory species are hinted at. Mr. W. Brewster describes 

 the breeding-habits of Clangula clangula americana, with two 

 plates ; Mr. W. Palmer treats of the "Ecology of the Mary- 

 land Yellowthroat and its relatives " {Geothlypis) ; Mr. J. O. 

 Snyder has a short paper on the Birds of Idaho and Wash- 

 ington ; Mr. Henshaw describes a new species of Shearwater, 

 Puffinus newelli, from Hawaii ; and Mr. A. W. Anthony 

 contributes an interesting account, with a plate, of the 

 nesting-habits of the Pacific-coast members of that genus. 

 The names of the thirty new species of birds described 

 by Mr. E. W. Nelson from Mexico may be left for the 

 Zoological Recorder, who will also note Mr. Heber's new sub- 

 species of the genus Hylocichla. Dr. T. H. Roberts gives a 

 very full account, with illustrations, of the nesting of Larus 

 frankliiii in Southern Minnesota, Avhich shows that it 

 breeds much further south than was supposed ; and Mr. 

 Outram Bangs sends notes on a collection of birds from the 

 Bahamas.
