center of abundance of the emperor goose, but from my experience I believe 

 the southern shore of Kotzebue Sound to be their favorite breeding ground. 



Dixon ^2 found these geese to be very numerous on the island. On 

 June 25 he saw flocks of from 7 to 20. He saw in all more than 100 

 birds, but none of those dissected showed signs of breeding, and he 

 found no recent nests. 



Collins procured two adults and two fully grown immature birds 

 with dark heads. The latter two, a male and a female, were shot 

 on September 21 ; an adult male was taken on September 18 ; and an 

 unsexed adult on October 2. All are in rather fresh plumage. All 

 w ere collected at Gambell. 



The immature male lias a little more white on the postero-median 

 portion of the abdomen than the female of corresponding age.

Nelson writes that during the summer of 1881 a number of these 

 geese were found feeding on St. Lawrence Island. 



Collins tells me that he saw some grayish geese there during the 

 summer of 1930, but was unable to shoot one. 



MARECA PENELOPE (Linnaeus) 



European Widgeon 



Anas penelope Linnaeus, Systeraa naturae, ed. 10, vol. 1, p. 126, 1758 (Europe; 

 restricted type locality, Sweden). 



Collins brought back an unsexed, undated bird, taken at Gambell. 

 By plumage it is a female and is clearly referable to penelope and 

 not to americana^ as it has a very rufous-brown head, and abundantly 

 graj^-freckled axillars. 



This duck has not been recorded previously from St. Lawrence 

 Island.

Nelson saw several pintails on St. Lawrence Island in the sum- 

 mer of 1881, but ajiparentl^y he did not collect any. Collins obtained 

 one immature male at Gambell in August. It is quite impossible to
