Jan 27 /60/  Gould shewed me the Heliothrix (Y) auriculata (a humming-bird) see [3 words illeg] (same remark applicable to other species genus) in which the female has much longer tail than male with the white outer feathers spotted on under side with black. This Hen is equally bright green on back but the male has splendid gorget & ear-tuft which Hen has not. The young male has longer tail than the old like the Hen: capital illustration of law! like [Macgillivray] case of Merganser Sexual characters most strongly displayed in many Humming-Birds & very pugnacious. But in some genera males & females nearly alike. Does Heliothrix nearly allied to group in which males & females are alike?

One reddish Humming bird looked dullish till you looked from behind then brilliant colour. The nestling of Wax-birds have the coral tips, & sexes are alike: so with quite young kingfishers
