The Canadian “ Crow” (Corvus corone, Linn.), rather more 
slender than our rook, has a quicker caw, and when several are 
calling together, their sound resembles a dog’s bark. P. H. 
Gosse (‘ Canadian Naturalist,’ p. 167) says: ‘“ This is one of the 
“few species which are common to America and Europe.” 
Twice I saw the Musquash, Fiber zibethicus (Cuvier). About 
4 million skins are cured every year. 
Sciuropterus volucella, the Grey flying squirrel, I saw at 
Dr. Brodie’s in Toronto. It is very gentle. The same gentle- 
man is one of the few that has the secret of handling live 
rattlesnakes. 
I heard the Skunk (Mephitis varians, Gray) at night whisking 
and snuffling round the hen-roosts. 
Of Aves, Ectopistes migratorius (Linn.) (the Canadian pas- 
senger pigeon), Dr. Brodie, Mr. G. Ogilvie, Mr. J. Downs and 
others assured me is almost extinct. 
The Toronto Biological Society are endeavouring to promote 
the study of living birds in the woods, to be identified by means 
of the T. B. S. type-collection, and thus to prevent the un- 
necessary destruction of bird-life. 
Ampelis cedrorum, Baird, the Cedar-bird, has a horny-red 
secretion or flake on one of its secondary feathers. 
The Black woodpecker is 18 inches long, has a red head; the 
contents of the stomach, when examined, are mainly black and 
red ants. 
The Canadian cuckoo sometimes makes a nest. From its 
irregular habits in egg-laying, Dr. Brodie has found in its nest 
fledged and unfledged young and fertile unhatched eggs. 
Uria Brunnichii, Sabine (Brunnich’s guillemot), sometimes 
comes up the St. Lawrence to Toronto Bay, unwisely, for it 
invariably starves to death. 
Passer domesticus, Linn. (imported), has driven the small 
Canadian birds from near houses into the quiet of the woods. 
Mollusca.—Varieties of Helia are scarce ; but the water-fauna 
is rich. 
Limnea stagnalis, Linn., occurs both as a stunted and also a 
very largeform. Physa and Unio occur in great variety. Kew,
