A LIST OF THE BIRDS OF PEGU. 211 
argument might, with equal justice, be applied to any other pair 
of similar species, and one of the two abolished. 
The present species has apparently the same distribution as 
the preceding. I note, however, that Lieutenant Ramsay got it 
at Tounghoo, where he does not seem to have observed melano- 
cephalus. 
222.—Otocompsa emeria, Lin. (460) 
Extremely common, commencing from Prome, extending 
down to Southern Pegu, and reaching up to Tounghoo, where 
Captain Ramsay wrote to me it was very abundant. Not found 
on the hills. 
223.—Pycnonotus burmanicus, Shorpe. Cat. VI., 
p- 125. (462 quat.) 
Of common occurrence everywhere in Pegu except the hills. 
I cannot find that birds differ at all from each other from one 
end of the province to the other. 
1 recorded the finding of the nest and eggs of P. intermedius 
in Pegu (8. F., V, p. 157). This note must be cancelled. It 
applies to P. burmanicus. 
224.—Phyllornis chlorocephalus, Wald, (463 dzs.) 
Confined to the evergreen forests of the Pegu hills from 
Rangoon up to the frontier, and pretty common. 
225.—Phyllornis aurifrons, Tem. (465.) 
Extends from Thyetmyo down the valley of the Irrawaddy, 
Ts common throughout Southern Pegu and runs up to Tounghoo. 
It is I think confined to the plains. 
226.—Iora typhia, Lin. (468.) 
Extremely common in all parts of the province in gardens 
and waste land. 
227.—Irena puella, Lath. (469.) 
Confined to the evergreen forests of the hills, and not 
descending far into the plains unless the forest is very thick. 
It is extremely common wherever it occurs. 
contrary, so far as we yet know, this partial inability appears to be rather sporadic, 
affecting only individual birds, and not general or common to the bulk of the birds 
anywhere. If this be so, we can no more admit einereiventris as a species, than 
we can the bright yellow Xantholema hemacephala, Paleornis torquatus, and 
purpurens, or any other of the fifty odd familiar, and constantly recurring forms of 
albinism and lutinism. I believe that this form is more common in Tipperah than 
elsewhere, but even there it did not seem to me to affect one per cent. of the 
birds. Still, if hereafter in any area this partial inability to secrete the yellow 
pigment shall prove to be a normal, persistent, hereditary characteristic of any 
considerable body of birds, I shall willingly accord specific rank to this form. At 
present, I must repeat, (and it is a question I have carefully studied) that all 
Sa is opposed to any such general diffusion of this peculiarity —
