Summary:
Seeks explanation of the case of the Rhynchaea, of which the female is more beautiful than the male, with the young resembling the latter. Wallace has told CD that at Nottingham AN explained this by the male being the incubator.
Does the male black Australian swan, or the black and white S. American swan, differ from the female in colour of plumage?
