SIBERIAN TIT. i 
and that he doubts if it ever breeds in the far north. 
In the catalogue for 1860 five eggs are inserted, taken 
also in Finnish Lapland. It is also included in the 
Scandinavian Fauna by jN’illson. M. Linden, the con- 
servator of the Museum of Geneva, states that this bird 
is also found in the Swiss Alps; but M. De Selys- 
Longchanips is of opinion that he mistook P. lucjuhris 
for it. 
I am indebted to Mr. Newton for the following in- 
teresting details of this bird: — ^‘My own opportunities 
of observing Parus Sibiricus were not sufficient to 
enable me to say in what particulars (if in any) its 
habits differ from those of the other species of the 
genus with which I am acquainted, beyond the fact 
that its call-notes are easily recognisable as distinct 
from anything else. Indeed from the information I 
have at various times received from the late Mr. John 
Wolley, I should suppose that in manners it closely 
resembles the rest of the Titmice. It is resident 
throughout the year in the district around Muonioniska, 
and as he has often assured me, was the only species 
which he found to breed there, although in autumn 
the Marsh Titmouse makes its appearance, and on one 
occasion, a solitary Great Titmouse was obtained by 
him. I am unable to give even an outline of the 
range of Parus Sibiricus in Lapland; but I do not 
remember seeing it until, in descending the river 
Muonio, we had entered the region of the Scotch fir, 
f Pinus sylcestris.) I never found a nest myself, or 
saw one m situ. It breeds in holes of trees, whether 
naturally formed by decay, or excavated by Woodpeckers. 
The nest is a mass of hair, principally from the lem- 
ming, or some of the voles, but occasionally from the 
alpine hare, mixed with a little green moss, black
