Genus Leucopareia, Reichenbach (1852 



Distinguished from Branta by tail-coverts not reaching the tips of the tail-feathers, the 

 latter being 14, and not 16, and by white areas on head. 



From Rufibrenta this genus differs by the unfeathered chin, the absence of rufous 

 colouring from the plumage, and by the greater number of teeth (not less than 30) on each 

 side of upper mandible. 1 From both genera Leucopareia is distinguished by the light 

 bluish cinereous grey colouring of upper surface of body, with sub-terminal black crescents to 

 feathers. From Leucoblepharon it differs by the shorter neck, white forehead, and the 

 character of the plumage.

1 In Rufibrenta the number of teeth, so far as I can yet judge, must seldom exceed 16. 



2 The name, perhaps, is given on Kolguev also to the red-breasted kazarka, for which see Buturlin's notice at end of book.
