 The tail is about 70mm. long. The bands of new grey 

 feathers on the sides of the neck meet in the middle 

 line on the throat and the sexual characters when well 

 developed are visible in the feathers of the back.

 fifth being 58mm. long and the first and second full 

 grown. The sexual characters of the median wing- 

 coverts are plainly to be seen, the remainder of the 

 plumage has greatly progressed, and the horse-shoe 

 has begun to appear. The central tail-feathers are full 

 grown — 75mm. long. 



071 the 8Qth day the third primary falls, the fourth 

 being 76mm. long. The bird is completely clothed in 

 its first winter -plumage, except for the head, the dorsum, 

 sides and lower part of the middle line of the neck, and 

 the external borders of the flanks. The yellowish-red 

 feathers have begun to appear on the forehead, throat, 

 cheeks and eyebrows of the males, and the horse-shoe 

 is apparent. The tail is full grown with the exception 

 of the two external feathers.

 developed. Two bands of old feathers extend from the 

 cheeks to the shoulders. The red wattle begins to appear 

 on the lower eyelid.

 lower half of the neck. The red wattles have begun 

 to appear. The feet are yellowish-brown and the 

 bill blueish-brown.

 neck at the apex of the bare space, and these are gradually 

 lost, the growth and full moult of the juvenile plumage 

 being thus accomplished in about four months.
