XHE Dun Diver*, or female, is less than 

 the male; the head, and upper part of the 

 neck are feiTuginous ; the throat white ; the 

 feathers on the hind part are long, and form a 

 pendent crest ; the back, the coverts of the wings, 

 and the tail are of a deep ash color ; the greater 

 quil feathers are black, the lesser white; the 

 breast, and middle of the belly, are white, tinged 

 with yellow. - ^ 



We believe that Belon-\ describes this sex 



* " Mr. Mo7ifagu in his ornithological dictionary, and Dr. 

 Latham in his Synopsis, the first supplement, and in his very cu- 

 rious treatise on the Trachece of birds in the fourth volume of the ~ 

 Linncean Transactions, considers the Dun Diver as a species dis- 

 tinct from the Goosander. In the second supplement, that able 

 naturalist seems to change his opinion, and informs us, " that 

 both sexes for the first season at least, have the appearance of the 

 Dun Diver, which the female retains throughout life, whilst the 

 male gradually gains the beautifully white plumage he is known 

 by." Ed.
