286 MR P. L. SCLATER ON THE CURASSOWS 
** When I had the pleasure of consulting several high authorities respecting this bird, 
they all agreed that it was the female of Pauai galeata, which for some time 
satisfied me. But one of the supposed black males of Pauai galeata in my aviary, small 
in size, has been seen to lay an egg, and has paired with the other black male, thus 
proving that the female in this species is exactly like the male, and not as described by 
you, P. Z.S. 1870, p. 519.” 
Under these circumstances, I think there can be no question that the normal female 
of the present species resembles the male in plumage, and that the red bird either is of 
a distinct species or presents the exceptional case of a dimorphic female. I rather 
incline to the latter view, because Mr. Rowley’s specimen was, I believe, received from 
the same port as his pair of the ordinary Pawai galeata, and because Temminck’ says 
of this species, ‘“‘Le plumage des femelles ne différe point: les jeunes ont des teintes brunes 
et rousses.” It may be, therefore, that in some cases the females remain throughout 
life in the immature plumage, as, I have reason to suspect, is sometimes the case in 
other species where the adult male and female are clad alike and the young hasa 
different dress.
