 daries, breaft, and belly, white : fides above the thighs black : 

 tail dufky : legs yellow. 



None of the birds we have hitherto treated of has caufed 

 more uncertainty in our minds about the identity of the 

 ipecies than this ; but we fear that thofe defcribed by Brif- 

 fon have not come under our inflection, at leafl his male. 

 Some years back I had a pair fent to me for Mori lions, which 

 differed from each other merely in having the head and neck of 

 the reputed male greatly darker than thofe of the female ; but 

 both were fo like the hens of the Golden-eye, that I was ftruck 

 with the circumftance : they were dried fpecimens, fo that the 

 internal conformation of the wind-pipe, &c. could not be de-

 in different periods of life; and that, although the feathers were 

 not the fame in the young birds as in the adult, yet the labyrinth 

 was to be feen in every ftage ; hence this circumftance, having
