which have occurred in the British Isles. They 
are : — 
Pallas’s Grey Shrike, Lanius major — a very doubt- 
ful species, of which we do not as yet know very much ; 
the Great Grey Shrike, L. excuhitor ; the Lesser Grey 
Shrike, L. minor, which has never bred in England ; 
-the Red-backed Shrike, L. collurio, by far the 
commonest ; and the rarer Woodchat-Shrike, L. senator. 
Of the Great Grey Shrike an albino is to be seen, 
I believe one of the rarest albinoes among British 
birds. 
In this case we see also the Waxwing, Bomby cilia 
garrula, or Ampelis garrulus, a bird which nests in 
Lappland, but visits England only in irregular intervals 
in winter, being a more regular winter bird in the 
northern parts of Germany. Pale and almost quite 
white varieties are here, which are extremely rare in 
this bird. The Waxwing leads us to the great family 
of Flycatchers, plentiful again in warmer climates, 
but only two species of which inhabit the British 
Islands, the Spotted Flycatcher, Muscicapa grisola, 
common everywhere, and the far less numerous Pied 
Flycatcher, M. atricapilla-, while a third very pretty 
species, the little Red-breasted Flycatcher, M. parva, 
similar to a diminutive Robin, is only an exceedingly 
rare straggler. 
Here also are the Swallows, of British species three, 
i.e. the Common Swallow {Hirundo rustica), the 
Martin {Chelidonaria urbica), and the Sand-Martin
