276 ORNITHOLOGICAL NOTES AND CORRECTIONS. 
comparison of a good series which I afterwards got of rufa, 
with our Indian bird, soon convinced me that I was wrong. 
The European and Asiatic Chiff-chaffs much resemble each 
other, so a word or two upon their differences will not be out 
of place. 
Tristis is not nearly so greenish above, nor so yellowish 
below as rufa. It is pale greyish, brown above, and dull fulvous 
white below; like rufa,it is rufous about the head, or strongly 
tinged with reddish white, the cheeks and supercilium especially 
shew this tint. ufa is olive above, and much more tinged 
with yellow on the lower parts. Both birds have the bright 
yellow axillaries and edgé of wing. While rufa is a rather 
richly toned Phylloscopus, tristis is, with the exception of 
neglectus, the most sober-toned of the group. 
With regard to the eggs said to be those of éristis taken by 
Messrs. Seebohm and Harvie Brown, I am not quite satisfied 
with them. They are exactly lke those of trochilus, but 
rather smaller than the average. They rest entirely upon native 
evidence, and were taken where ¢rochilus is common. ‘They there- 
fore require confirmation. I should expect the eges of tristis to 
be more like those of rufa, viz. spotted with dark purple brown, 
instead of light red. Still the eggs may be those of éristis which 
time will shew. Vide Ibis for ‘April 1876. 
Phylloscopus xanthodryas, Swinhoe. 
Is a very distinct species, similar in coloration of upper 
surface to P. magnirostris, but rather greener ; and its lower 
surface is different, being a rather clear greenish yellow, more 
inclined to green than yellow. It is less infuscated on the 
sides of the breast and flanks than magnirostris. The second 
primary equals the 6th. Itis about the same size as magni- 
rostris. 
Phylloscopus plumbeitarsus, Swixhoe. 
Is also a good species. It isabout the sizeof P. viridanus, 
and has two wing bars. It is somewhat greener than that 
bird, and its supercilium i is broad andlong. The bill is stouter 
than in viridanus, being more of the magnirostris shape. Dried 
skins do not shew the colour of the legs and feet as different 
from those of viridanus, but no doubt the lead color is apparent 
in fresh examples. The second primary is equal to the seventh. 
Phylloscopus tenellipes, Swinhoe. 
Another good bird; is asmall Phylloscopus of entirely differ- 
ent color: ation, brownish olive, above and passing to very rufous 
olive on lower back and tail. The head is inclined to greyish
