China and Cambodia constituted the winter-quarters of this 
species. A species with a black tail, T. atricaudata } which 
Mr. Blyth considers identical with our bird, has been procured 
in winter plumage in Malacca. In autumn for a few days again 
we are visited by this bird, but it is then in its winter plumage 
and shorn of its handsome tail-appendages. 
Xanthopygia narcissina , Schleg., and Hypothymis cyanome- 
lana, Schleg., would also be naturally expected to touch at 
Formosa on their passage to Japan; but the latter of these may 
possibly cross the sea higher up the coast, as its summer migra¬ 
tion extends right up to Peking. The former, however, is re¬ 
placed in the north of China by a closely allied and more elegant 
white-eyebrowed species, the X. leucophrys, Blyth. I procured 
neither of these birds in Formosa.

This is the common Flycatcher of Formosa, and is, I think, 
a resident species; for I observed it in numbers, as late as No¬ 
vember, in the bamboo-groves of the south-west. It is more 
sparsely distributed in the hilly regions of North Formosa. 
d. Length 6^ in.; wing 3; tail 3. $ of the same size, with 
rather shorter wings. 
Male with upper parts and breast fine azure-blue, a patch of 
deep black on the occiput, and a deep-black band across the 
breast. Axillaries in part, and lower belly and vent, white. 
Wings and tail blackish brown, strongly washed with azure. 
Tail somewhat graduated, the tips of the feathers being pointed. 
Female dingy azure on the crown, throat, and carpus, the 
breast and flanks being bluish grey. Upper parts brown, the 
tail only being washed with bluish grey on the outer webs of its 
feathers. Belly, axillaries, and vent white. 
In fresh specimens of both sexes killed 6th August, 1861, the 
bill is light clear cobalt-blue, with black tip and edge. Legs 
and toes violet, with yellowish-grey soles. Inside of mouth 
greenish, yellower on the palate and tongue. Tongue concave, 
bulging at the sides, crenate at the tip and split, horny. Skin
