no determined colour. The bill and lore were of a yellowish 
flesh-colour, very pale, and tinged with blue. The legs of a 
similar colour, with pale claws. The head and back were covered 
with a long blackish down, and the rest of the body with more 
or less whitish down, somewhat resembling sheep's wool. The 
black down on the head was drawn out into long white tufts, 
which stood out from the head like a crown of thick threads. 
In the larger chick, the eye was of a pale sea-green ; the lore 
and bill were tinged with yellowish green. The long down of the 
head had opened out into filamentous ends. The legs were bluish 
sea-green above, and sienna-yellow beneath. The bare skin of the 
round projecting belly was sea-green, as also the dorsal skin. The 
colour of the down was light purplish grey, tipped with white 
on the crown, and giving place to white on the flanks and belly. 
The cry it uttered was a weak imitation of the old bird's croak. 
The immature plumage of the yearling appears to undergo little 
change until the second winter, or until the bird is over two 
years old. One of the nests taken was covered by a bird in this 
first plumage, and the eggs were found to be narrower and of a 
darker blue than those of the mature bird. An individual in 
immature plumage was brought to me by a native, and the de¬ 
velopment of the testicles was proof positive that the bird in this 
plumage bred. It would be curious to inquire whether those in 
the mature plumage pair with those in the immature. I have 
certainly seen them together, but never ascertained whether two 
such owned the same nest.

A number of Ascarides were found in and about the intes¬
