Bush-birds of New Zealand. 543 
Warbler (Pseudogerygone) which he procured in the bush at 
Maungahaumia, at an elevation of 2000 feet. He says that 
the bird appears to differ from lowland examples of P. flavi- 
ventris (G. R. Gray) in having the iris dull yellowish-pink 
instead of clear bright red, almost crimson. Of the two 
male specimens forwarded by Mr. McLean, one (no. 143) is 
fully adult, while the other is apparently a bird of the year. 
In the general colour of the plumage of their upper parts both 
resemble the three examples of P. igata (Q. & G.) procured 
by Lord Ranfurly from Dusky‘ Sound, South Island, and 
recorded in my paper on his birds (ef. ‘ Ibis,’ 1905, p. 588), 
but the rump is more like the back and not of so brown an 
olive and there is a conspicuous black spot in front of the 
eye which is wanting in P. igata; the latter, moreover, has 
the iris black. 
Mr. McLean’s birds differ much from specimens of 
P, flaviventris, the type of which is fairly well figured in the 
Voyage of the ‘ Erebus’ and ‘ Terror’ (Birds, pl. iv. fig. 1). 
Of P. flaviventris there are six specimens in the British 
Museum, one immature and five adults in worn plumage; 
of the latter, three from the Bay of Islands (including the 
type specimen) were no doubt procured in the breeding- 
season, having been collected at some date between the 18th 
of August and the middle of November (cf. Hooker, Voy. 
‘Erebus’ & ‘Terror,’ p. vil). 
In mentioning what appeared to be the characteristic 
differences between P. flaviventris and P. igata in the paper 
cited above, I may have laid too much stress on the difference 
in colour of the plumage without making sufficient allowance 
for seasonal change. It is a fact that the adult specimens of 
P. flaviventris in the British Museum are in worn breeding- 
plumage, while the birds sent by Mr. McLean in freshly- 
moulted plumage were killed in winter (26th of May and 
the 9th of July), as also were the specimens of P. igata sent 
by Lord Ranfurly and procured in March, June, and July. 
It is impossible that Mr. McLean’s birds with their 
characteristic black spot in front of the eye can be P. igata. 
They are also apparently distinct from P. flaviventris, but it
