WHITE-TAILED EAGLE. 537 



particularly indebted for sending- us both sexes of Anas nyroca^ for 

 examination. From the information of this accurate naturalist, this 

 bird appears to be not so uncommon in the London market, as might 

 be expected. Since it has been considered as British, seven or eight 

 have been examined by Mr. Foljambe, several of which were fresh, 

 and varying" a good deal in plumage ; some having no white either 

 in the wings or under parts of the body : these were probably young 

 birds. 



The weight of the female was about thirty-six ounces ; length 

 eighteen inches ; breadth the same. The male described above weighed 

 thirty-three ounces and three-quarters, and measured in length sixteen 

 inches and a half. 



There is very little difference in plumage between the male specimen 

 belonging to Mr. Foljambe, and that in our collection ; but being- in 

 better feather, it is observable that on the lower part of the neck, the 

 fine chestnut colour is interrupted by a dusky ferruginous collar, which, 

 passing behind, becomes blended and uniform with the colour of the 

 back ; from the vent to the tail-feathers pure white ; the rump and 

 upper tail-coverts dusky black, coming down on the sides in the 

 line of the vent, forming- a strong contrast with the white feathers be- 

 neath. 



The female very much resembles the other sex in plumage, but the 

 colours are not quite so strong-, especially the chestnut on the breast, and 

 the white beneath is not so pure ; the white on the chin is not so ex- 

 tended, nor is there any black that borders the white on the sides be- 

 hind the vent ; the legs, as well as the toes, are paler. The irides of 

 both sexes are yellow. 



This species belongs to the diving family of ducks, all of which 

 have short wings that scarcely reach beyond the base of the tail when 

 closed. *
