The male begins to assume the characters proper to his sex shortly before the age of reproduction; if emasculated he either never acquires. or loses these characters or subsequently loses them; in in both classes the change of colour is sometime annual seasonal, & the tints of the naked parts sometime become more vivid at the actual period time of [text excised] almost all cases when there is any difference in colour the male [text excised]

In the young if both sexes & in the adult females these protuberances are scarcely perceptible; & in all with & the naked part is are less brightly coloured, & the face is being of a uniform pale blue.
