Mr. Wallace [vide Ibis, 1868, p. 16) speaks of the colour 
of the iris in the birds of this genus from Malacca, Sumatra, 
’ Timor, Flores, Borneo, Philippine Islands, and India (all 
■wbicb be includes under H. indus) as dull yellow,^^ and in 
those from Celebes, all the Moluccas, and New Guinea,^^ 
(which he refers to H. girrenera) as olive-brown but 
both are probably liable to some variations. Mr. Gould, in 
his great work on the ^ Birds of Australia,^ speaks of the 
irides in adult Australian specimens as light i eddish yellow,^^ 
and in his ^ Handbook,^ subsequently published, he adds 
that immature birds have darker-coloured eyes than the 
adults. The adult bird from Percy Island which is preserved 
in the Norwich Museum was noted by the collector as having 
a reddish chocolate iris. Professor Schlegel, in his Walk- 
Vogels,’ p. 51, gives, on the authority of S. Muller, the colour 
of the iris in the adult as brun clair,^^ and in the young as 
^^brun:^^ MiilleFs specimens in the Leyden Museum were 
obtained from Sumatra, Macassar, Amboina, and Western 
New Guinea; and his observation, no doubt, related to these 
or to some of them. Indian specimens, according to Mr. 
Hume (^ Scrap-book,^ p. 316), have the irides brown,’^ and 
those found in China are described by David and Oustalet 
(' Oiseaux de la Chine,^ p. 15) as having them of a brun 
chatain.^^
