He estimated the number of assembled males at above a hundred, the females, which lie hid in the surrounding bushes, not being counted.

122. Reviewer remarks that whilst in 2 species of Chlöephaga & in the Bernicla antarctica the sexes are so (O) differently coloured that they might easily be mistaken for distinct species, in 2 other species of Chlöephaga the male cannot be distinguished from f. except by size.

p 366 Mr Swinhoe on platalea remarks that in spring of 2nd year female is advanced to appearance of m. of 1st spring & the male is fully developed. In 3rd spring female wd P probably be identical with old male (P)
