320 Mr. J. H. Gurney’s Notes on 
contains at p. 551, in the last paragraph but one, the descrip- 
tion of a male and female from Peru in the second or rufous 
stage, but just beginning to change into the third phase of 
plumage; both these specimens are described as having the 
bill black on the upper mandible, and yellow on the lower, 
the irides white, slightly tinged with yellow, and the feet 
earrot-yellow. 
The female from Tehuantepec in the Norwich Museum is 
also in the second stage of plumage, and is marked by the 
collector “‘ Jeune femelle: iris blanc-perle, pieds jaunes ;” it 
was shot in the month of November. 
The male from the same locality, which is preserved at 
Norwich, and which was killed in January, has passed into 
the third stage of plumage, with the exception of a consider- 
able amount of rufous colouring still mingled with the trans- 
verse grey and white bands of the under surface ; and another 
male, in a similar state of transition, which was obtained in 
Peru, is recorded by M. 'Taczanowski in the P. Z. 8. for 1879, 
p. 242, in the third paragraph of his note on this species. 
The two specimens in the collection of Messrs. Salvin and 
Godman from the Upper Amazon and from Bahia, and that 
from Peru in the British Museum, have all nearly attained 
the third stage of plumage; but the last-named example would 
seem, from the remains of its earlier dress, which it still 
retains, to have passed direct from the first to the third stage, 
without making a transit through the second, an irregularity 
which also partially, if not wholly, happens, as I have already 
observed, in R. wncinatus. 
The type specimen from Peru figured in the work of Cas- 
telnau and Deville, pl. 1, is represented as having completely 
attained the third stage of plumage ; and the following note 
is there given of the colours of the non-feathered parts :— 
“‘Viris de cet oiseau est blanc, le tour de l’ceil bleu, la peau 
nue du sourcil orangée, la cire et les pattes sont d’un jaune 
verdatre clair.” 
Another Peruvian specimen, a male, described in the second 
paragraph of M. Taczanowski’s note’ in the P. Z. 8. for 1879, 
p. 242, is shown to be somewhat older than the type, from the
