Mr. R. Swinhoe on Formosan Ornithology. 261 



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. 



22. Myiagra azure a (Bodd.). 



Muscicapa caerulea, Gmel. M. occipitalis, Vigors. 



M. caruleocephala, Sykes (the female). 



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. 



6 . 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 

 round the eye black; iris blackish brown. Ear small, oval, and
