204 Mr. R. Swinhoe on a new Form of 
compared it with skins in the East-India Company's Mu¬ 
seum, and came to the conclusion that it represented a second 
species of Hodgson's genus Tribura , of which the type is 
Tribura luteiventris of Nepal. I consequently described it in 
the Proceedings' of the Zoological Society of that year as 
Tribura sqicamiceps. On the 8th of May, 1866, I received 
among a lot of birdskins from Takore, Formosa, a second 
specimen of this species, which my hunters had procured in 
the mountains in the interior of that district shortly after 
my departure for Amoy. This skin was sufficiently perfect to 
show that the bird had a short graduated tail, and not a 
long tail, as Tribura. 
I never met with this species in China myself; but as I 
was leaving Chefoo on the last occasion, I received from Mr. 
Blakiston my third specimen, which he had procured at Ha- 
kodadi, Northern Japan, in May 1873. This specimen had 
nearly a complete tail (see Ibis, 1874, p. 155). 
M. Taczanowski, of Warsaw, under date 9th November, 
1875, transmitted to me a fourth specimen of the same bird 
from the Ussuri district. This is a male, shot on the 25th 
of September. I have the species therefore from Canton, 
Formosa, Hakodadi, and now from Manchuria, which, I think, 
proves pretty well that it is a regular migrant, coming north 
in summer to breed. 
Mr. W. E. Brooks, who is now at home, writes to me from 
near Newcastle saying that he believes that he has an example 
of this same species, which was procured in Tenasserim. Mr. 
Brooks encloses me a good drawing of his specimen, which 
confirms his identification. 
Mr. Brooks urges me to have a figure of this bird pub¬ 
lished, and to assign to it the characters of a new genus, as 
he considers that it does not belong to Tribura , Pnoepyga , 
Horornis, or any other known genus, though it has certain 
characters in common with them. I think, therefore, that 
it would be as well to propose for it the generic name Uro- 
sphena , from its wedge-shaped tail, and to characterize it as 
follows :—
