Turnstone, and last, but not least, Steller's Western Duck!! 
Guernsey supplies us with the Calandra Lark; Portugal, with 
White's Thrush; the Isle of Ushant, with Macqueen's Bus¬ 
tard; Norway, with the Curlew Sandpiper; Uist, with the Red- 
throated Pipit, Pectoral Sandpiper, and Great Northern Diver. 
Several pairs of the Two-barred Crossbill have bred at Loch 
Fyne, to say nothing of the Jack Snipe; while we are offered the 
Brown Snipe (Macrorhamphus griseus), with the bird that laid 
the eggs, from Pwllheli in North Wales ! Many additions to the 
British fauna are presented for the first time, Arran enriching 
our list with specimens of Circaetus gallicus and Sterna tenuiros- 
tris. The catalogue is appropriately wound up with the egg of 
the Bimaculated Duck, from Siberia, and the travelling-case in 
which all these prodigies were exhibited to the wondering gaze 
of Dr. Thienemann.

collecting friends, and remembering that truth—truth for its 
own sake—is the one aim and object of the naturalist, to 
denounce all shams, all indulgence of the passion for merely 
amassing, and to let their cabinets, as well as their studies, be 
like Caesar's wife. 
I am, Sir, 
Your obedient Servant, 
Oophilus. 
During the past month numerous instances of the occurrence

and the neighbouring parts of the Continent have taken place. 
One of our most valued contributors has promised us an account 
of this new immigration from Tartary for our next Number.
