colour, and the outer feathers have nan-ow white edges. Tlie 
under surface of the wing and tail-feathers are dark grey, and 
the inner webs of the wing-feathers are edged with silvery- 
w'hite ; the under wing-coverts are dirty-white, tinged with 
rust-yellow^ The iris is dark brown ; the beak black; the 
legs pale lead-colour ; the claws greyish-hora. 
The crest of the female is shorter than that of the male ; 
the black on the chin is not so far extended, and the black 
border round the neck is much narrower and frequently im¬ 
perfect. 
The young birds, before the first autumnal moult, have 
the crest small, the black round the cheeks imperfect, and 
the collar hardly visible. The chin is nearly black, the 
throat grey ; the breast is dirty-white, and all the under parts 
are intermixed with grey. 
The entire length of the Crested Titmouse is four inches 
and three-quarters. The wing measures, from the carpus to 
the tip, two inches and a half; and the tail extends about 
an inch beyond the folded wings ; the tarsus measures three- 
quarters of an inch; and the beak about three and a half 
lines, from the forehead to the tip. From the forehead to 
the end of the longest feather of the crest is about an inch 
and quarter, and the fourth quill-feather is the longest in 
the wing. 
In the autumn of 18S9, during a rough gale of wind from 
the north-west, we observed in a fir-wood near Claremont 
House in Surrey, a small bird apparently of this species, but 
being unable to obtain the specimen, we could not ascertain 
the fact. It is possible that a Crested Titmouse might have 
been driven so much further south than its usual supposed 
limit by a strong wind. 
The egg of this species is figured 80 in the plate.
