stretched backwards. Weight 10 pounds.* Iris dark brovvu. Bill brownish black, 

 with a clear yellow band across the bill. 



Not long after the drawing (pi. vii, fig. 1) was made the color changed to a brownish orange, paler 

 and more approaching flesh-color anteriorly. Feet orange, with more yellowish webs, and black 

 nails. Eather lean. 



No trace of white on feathering bordering the bill. 



9 ad., U. S. Nat. Mus. No. 92825, L. Stejnegcr, No. 2023 ; Ladlginak, Bering Island, 

 May 10, 1883. 



Middle toe reaches 68'""" beyond the tail. Weight 8f pounds. Iris dark brown. 

 Color of bill very much as in the specimen above, the yellow, however, being of a 

 paler shade, and not extended behind the nostrils. Feet as in the foregoing. Eather 

 fat. Eggs swollen, the largest one having a diameter of 15""". 



Feathering along the base of bill with faint traces of white semilunes, these, how- 

 ever, being strongly tinged with rusty. 



Grebnitski's specimen (No. 101207) is very much like the latter, but 

 there are faint yellowisli mottlings along' the lower border of the nos- 

 trils, and no trace of white on the feathers encircling the bill. 



This goose, which is said to be very common in many parts of Kam- 



tschatka, is not of regular occurrence on Bering Island even during the 



migrations. The ai^ijearauce of a small flock in May, 1883, out of which 



the present pair were shot, was due to the same cause which brought 



so many Kamtschatkau species over to the islands. From Governor 



Grebnitski I afterwards received a specimen shot on Bering Island

Schlegel has already pointed out that the Japanese white fronted 

 geese belong to the large American form which, by Hartlaub, has been 

 called gambeli, and Nelson gives it as occurring on the Siberian coast of 

 Bering Sea. The specimen obtained by me on Bering Island confirms 

 these statements, since it certainly belongs to the typical A gambeli, as
