shorter, and the green of the back is darker, without so much of 
the yellow tinge. My single specimen I have been able to 
compare with one sent me by Mr. Blyth; but I dare say, if I had 
a series of both, the resemblance would be found to be still more 
complete. At present I do not feel justified in separating them. 
Our bird, when fresh, had the bill a light wood-brown, paler on 
the lower mandible, with yellow rictus. Legs light brownish- 
ochre flesh-colour, the claws being tipped with brown. I never 
saw this bird alive, and can therefore record nothing of its 
habits. In form it seems to connect the Willow-wrens [Phyllo- 
scopus ) with the Pycnonotidce. Length 4^ in.; wing 2^ in.; 
tail in., of twelve equal feathers; bill j in. Upper parts 
yellowish olive-green; crown-feathers large, with blackish shafts. 
Shafts of tail-feathers blackish brown. Shafts and inner webs of 
primary and tertiary quills deep brown, blacker on former. 
Cheeks and under-plumage brownish grey, more or less whitish. 
Axillaries, under-edges of quills, and vent greenish yellow. Bill 
somewhat conically shaped. Legs and feet strong, hind toe 
remarkably so. 
This species is recorded from Nepal, Arracan, and Malacca, 
and is probably also found on the mountains of Southern China.

Z. japonicus, mihi, Ibis, 1861, p. 35. 
Length 4 in.; wing 2 in.; tail 1 in., of twelve nearly equal 
feathers. Bill and legs leaden or slate-colour. Iris blackish 
brown. A ring of white feathers round the eye. Upper parts 
yellowish green, yellower on the head. Forehead, throat, under¬ 
neck, and vent sulphur-yellow. Axillaries white. Under-parts 
light brownish grey, with sometimes a ruddy tinge diffused. 
Quills and tail dark hair-brown, margined exteriorly with 
yellowish green. Under-edges of quills and under-shafts of 
quills and rectrices white. 
This species may be at once distinguished from the Northern 
Chinese species* by the absence of the deep rust-colour on 
the flanks and sides of breast, by its smaller size, and by the 
* The Zosterops of N. China ( Z . erythropleurus, mihi) is not identical 
with the Japanese species, as I have recently ascertained. See P. Z. S.
