32. DAFILA. 



279 



Immature male. Resembles the female, but has the wings as in 

 the adult male. 



Young. Eesembles the female, but has the feathers of the lower 

 parts centred with brown streaks. 



Young in doivii. Similar to the young in down of D. acuta, but 

 the sides of the head distinctly rufescent ; a tinge of the same 

 ai)pears also on the throat, breast, and sides. 



The tj'pe of this species is an immmature male, and does not show 

 the characteristics of the genus, which are quite evident in the 

 fully adult male — almost a miniature of the male Pintail. 



Hab. Kerguelen Island, and apparently also Crozette Islands.
