long tail, is not migratory, and would therefore seldom cross the 
eighty miles of sea that divides Formosa from China. 
31. Lanius lucionensis, Linn. 
This species of the red-tailed group of Shrikes, of which L . 
phoenicurus } L., is the type, is a summer visitor to Northern 
China, I having myself met with it as far north as Talien Bay. 
In spring and fall it abounds at Amoy for a few days, and then 
disappears, on its vernal migration into the interior and North of 
China; and in autumn across the sea to the Philippines, where it 
hibernates. In its line of migration it touches S.W. Formosa, 
and there we had its company for a few days in the early part of 
September. Its chattering note is very different from that of 
the preceding large species; and it is of more skulking habits, 
seldom showing itself in any conspicuous place. It possesses a 
melodious song of no mean capacity, but it is generally uttered 
in a subdued tone. It feeds on large insects, especially Lihellul(B } 
but oftener, I think, on small birds, more particularly of the 
Phylloscopus group. The migration of P. sylvicultrix , nobis, 
unfortunately for that bird, takes the same route as that of this 
butcher, and consequently the latter always has his food at hand. 
The arrival of the one bird is slightly in advance of the other. 
My specimens from Formosa are identical with those procured 
from Amoy, whence I have an immense series of skins, varying 
in numerous instances, with strong tendencies in colouring to its 
congeners of the same group; but my remarks on them I must 
reserve for another paper which I have in preparation on the 
birds of China. 
32. Cinclus pallasi, Temm. 
I believe the Formosan Dipper to be the same as the Japanese 
bird, though I have not been able to compare skins. Our bird, 
when alive, has the bill and legs a dark leaden colour, the latter 
with a purplish tinge, the claws being whitish on the under 
parts. In dry skins, of course, these parts change colour, the 
bill becoming brown and the legs whitish ; hence the Prince of 
Canino’s mistake in giving as a character of this species, “ rostro 
pallide fusco; pedibus albicantibus.” I suspect that the bill
