118 THE ZOOLOGIST. 
Neither were we able to find them anywhere near Tring, 
doubtless from want of suitable localities ; nor could we procure 
any more from our correspondents. There can, however, be no 
doubt that there are many suitable localities in England where 
this bird is found, and I hope ornithologists will look out for it, 
and procure some specimens in autumn, as soon after the moult 
as possible, for it is a pity to shoot any when they are in abraded 
dirty spring plumage, which in Tits is rather poor, as everybody 
knows. 
More detailed accounts and figures of P. salicarius can be 
read in the ‘ Ornitholog. Jahrbuch,’ vol. viii. Heft 2, and in the 
‘Journal fiir Ornithol.’ 1897, no. 2 (April). These articles show 
that the forms of the Marsh Tits by no means form a chaos out 
of which it is too difficult to find a way, but that with some 
study they become a very clear group. The British speci- 
mens of P. salicarius, it may be added, differ a little from conti- 
nental ones in being somewhat darker above, and having shorter 
wings; but more material will be necessary to decide about the 
constancy of these characters. In any case there is no doubt 
that another species, not a subspecies, must be added, as P. sali- 
carius, Brehm, to the British list. As this species is a resident 
bird, and as all Marsh Tits are resident birds, there can be no 
doubt that the Willow Tit, as this bird may appropriately be 
called, will be found all the year round in suitable localities in 
Great Britain and perhaps in Ireland.
