408 ON THE IDENTITY OF DRYMOIPUS TERRICOLOR, 
all the lateral feathers, with greyish white tips and a penultimate 
dark bar. In June all the birds appear to have got new tails, 
but in a good many of these the dark spots on the tail feathers 
have disappeared, and the lateral ones have become mostly white. 
No longicaudatus tail is then seen until October. In November 
almost every bird has a new typical longicaudatus tail. 
It is not, however, all plain sailing as I shall show a little 
further on, abnormal birds occur which do not conform to 
these views. 
To take my series; there are seven birds killed in May, from 
Sambhur, Cawnpore, and Dehra Ghazi Khan; these are all 
pale earthy grey above, below whitish with the faintest yellow 
tinge, and most of them have, or are getting, new tails of the 
pale earthy grey type. 
In June there are seven birds, from Sambhur and Saugor. 
Six of these are typical terricolor with new tails of the short 
type, but the seventh is a young bird, very rufescent, of the 
longicaudatus type, and it occurred to me that the young of this 
species might be rufescent; I have often seen them in the nest, 
but I cannot myself remember. But Captain Bingham assures 
me that he has recently continually handled the young of this 
species, and that they are grey like the old birds, I cannot 
therefore account for this very rufescent June bird which is 
clearly a bird of the year. 
July, two specimens, one from Jhansie, one the Central Pro- 
vinces ; the Jhansie bird is typical ¢erricolor, but the Raipoor 
bird is a typical adult longicaudatus, in what looking to the rest 
of the specimens I should call the December plumage. I 
owe this specimen to Mr. F. R. Blewitt, it is dated Doon- 
dagurh, Raipooor Dist., 12th July 1874; if no mistake has 
occurred it certainly presents a considerable difficulty. It is the 
only clear exception to the view I now adopt, of longicaudatus 
being the winter and terricolor the summer plumage, out 
of one hundred and twenty specimens. 
Hight specimens killed in August from Hansi, Agra, Saugor, 
Jhansi, and Etawah are all in typical terricolor plumage. 
So also are two specimens killed in September from Dinapore 
and Mogul Serai. 
Of four specimens killed in October, one has nearly moulted 
into the longicaudatus plumage, but is not very rufous, though it 
has a typical longicaudatus tail, another has a new longicaudatus 
tail and is a faded rufous above, in fact it looks to me like a faded 
edition of the young June bird already mentioned but with a 
new rufous tail ; two specimensare in terricolor plumage, but with 
a slight rusty tinge not observable in any of the specimens 
of the previous month.
