brown, of a darker shade than the quill feathers, and form a dark- 
ish patch beyond the second wing bar. The wing is thus, in its 
whole appearance, extremely like that of Regu/loides superci- 
liosus. On the crown of the head is a very distinct coronal 
streak, similar to that of Reguloides proregulus, and of the 
same dull yellow colour; the supercilium is yellow and bright- 
er anteriorly ; the cheeks are yellowish, faintly mottled with 
pale brown; a brownish streak passes through the eye ; irides, 
dark brown, bill brown, and light yellow brown on lower 
mandible, except the tip, which is dark, as in the upper one ; 
legs and feet, brown. 
Length, 4 to 4:25 inches, according to sex ; wing, 2°2 to 2°3 
of the male, and 2°0 to 2:05 of the female; tail, 1-7 to 1°83 of 
the male, and 1°5 to 1:7 of the female; bill at front, -3; tarsus, 
*65 to °7. 
The 4th quill is generally the longest ; 5th a shade shorter ; 
3rd shorter than 5th, and intermediate between it and the 6th ; 
2nd equal to 8th; but sometimes intermediate between 8th and 
9th ; the 4th and 5th are rarely equal; and still more rarely 
is the 5th the longest in the wing ; the Ist quill is from 1:17 to 
1:08 short of tip of wing ; accordirg to sex. 
The general tone of colour is strikingly like that of Megulot- 
des proregulus, Pallas, but paler and duller; and it differs from 
that bird in not having a yellow rump band; also in its more 
slender and much lighter coloured bill. From Reguloides su- 
perciliosus, Gmel., it differs in having the supercilium of a de- 
cided yellow, while that bird’s is ruddy white or pale buff; and 
its cheeks are of the same colour, but duller, mottled with light 
brown. Our new bird’s cheeks, on the contrary, have generally 
a strong yellow tinge; its coronal streak too is bright and well 
defined asin Leg. proregulus; while the coronal streak of &. 
superciliosus is seldom visible, and when so, is merely a_ faint 
brownish grey line on the dark olive brown head which can 
only be seen when looked at in certain lights. The indistinct- 
ness, or entire absence, of the coronal streak is one of the 
characteristics of Reguloides superciliosus. All the others, 
except Reguloides castaneiceps, have the coronal streak very 
distinct. In our new species, the plumage is very soft and lax ; 
and, however, carefully the skin may be put up, the coronal 
streak gets disturbed and out of place. 
Unlike the purely hill Reguloides, 2. proregulus, R. erochroa, 
R. maculipennis, and R. castaneiceps, our bird is migratory, 
and frequents the plains of the North-Western Provinces dur- 
ing the cold season. The four species which I have just men- 
tioned find the lower Himalayan hills quite warm enough for 
their winter retreat.
