250 Letters, Announcements, fyc. 
three fourths of the tarsus are feathered in front; the two 
outer tail-feathers on each side are tipped with white, more 
broadly in the male; and both sexes have white spots on the 
first three primaries. Now C. mahrattensis is distinguished 
by precisely these characters, except that the tarsus is only 
about half concealed by feathers in the specimens I have ex¬ 
amined. I should add that Lord Tweeddale first pointed out 
to me the close agreement between the description of C. un¬ 
wini and the characters of C. mahrattensis. 
When I told Mr. Hume of the conclusion at wdiich I had 
arrived, he assured me I was mistaken, and placed the whole 
of his specimens at my disposal for examination. He at the 
same time said that his only doubt was whether C. unwini 
might not prove to be a variety of C. europceus. At the time 
he described the former, his only specimen of C. europceus was 
a large English female. A male specimen, from Europe, but 
without precise locality, has since been added to his collec¬ 
tion ; and I find that this agrees well with the types of C. 
unwini. 
The conclusion at which I have arrived, after examining all 
the specimens, is, that the sex of one of the types of C. unwini 
was probably wrongly determined, and that, instead of being 
male and female, both skins are those of males, that they are 
quite distinct from C. mahrattensis, but that they belong to the 
pale-grey race of C. europceus, of which I obtained specimens 
in South-eastern Persia, and that, whilst the name of C. un¬ 
wini must become a synonym, C. europceus must be added to 
the Indian fauna. Besides the two original types from the 
Agror valley, in Hazara, in the extreme north of the Punjab, 
Mr. Hume has since obtained a female without any white on 
the tail from Mari (the sanitarium somewhat further east); 
and he is inclined to refer to the same species two other 
females, one from Sirsa, in the Punjab, the other from Etawah, 
in the north-west provinces. These latter, however, are 
doubtfully identified, being smaller in all their dimensions ; 
one of them is certainly immature. It will be curious if 
this proves to be a resident race, and not migratory, like the 
western form.
