Mr. Stone deserves great credit for the present paper, which is a good 

 basis on which to build a better knowledge of plumage changes. Such 

 work is tending rapidly to disprove the many guesses formerly so 

 common but now gradually being displaced by the results of unbiased, 

 systematic study. — W. P. 



Stone on Birds collected in North Greenland. 1 — Mr. Stone gives an 

 annotated list of the birds "obtained by the Peary party during their 

 sojourn in North Greenland from July, 1891, to August, 1892, and also of 

 those collected by the Relief Expedition of 1S92." They consist of 122 

 specimens, besides numerous nests and eggs, part of which were collected 

 by Mr. Langdon Gibson in the vicinity of Peary's winter quarters, and 

 the remainder by Mr. Charles E. Hite, at various points from Disko to 

 Cape York. The two collections number 19 species each, and collectivelv 

 represent 2S species, only a part of the species being common to both 

 collections. The annotations give the localities, and generally the dates, 

 of the specimens obtained, with occasionally further notes of interest. 

 No species are added to the Greenland fauna, but the breeding grounds of 

 Chen hyperborea nivalis appear to be for the first time here made known.

Schalow on a Collection of Birds from West Greenland. 2 — In 1S92 the 

 Geographical Society of Berlin sent an expedition to West Greenland, 

 under the direction of Dr. von Drygalski, which was accompanied by 

 Dr. Vanhoffen as naturalist. The region explored extends from latitude 

 69 to 73 , and the expedition remained in the field from May, 1S92, to 

 October, 1893. The birds collected number 29 species, of which 12 are 

 represented only by eggs. Dr. Schalow, in his report upon this col- 

 lection, includes also notices of a number of additional Greenland birds' 

 eggs contained in the collection of Major Kruger-Velthusen ; some 35 

 species are thus formally noticed, with passing remarks on a number of 

 others. Many field notes are given, apparently extracted from Dr. Van- 

 hoffen's previously published observations, 3 with many technical notes 

 on various species. While the collection gathered by Dr. Vanhoffen added 

 no species to the Greenland fauna he reports seeing a skin of Tadorna 

 casarca [ = Casarca casarca (Linn.)] in a small collection of bird's skins 

 made at Augpalartok, in the District of Upernavik, which was collected
