1. Salmo Umbla, Lin, the char of Eng. Salmo Alpinus, Lin. 
Found in England, Ireland, Sweden, and all South Germany. 
2. Salmo Fario, Lin. The trout of brooks,—common trout, dis- 
tribution extensive as the above. 
3. Salmo Trutta, Lin. Sea trout,—Salmon trout. Salmo Lema- 
nus of Cuvier, distributed extensively as the preceding. 
4. Salmo Lacustris, Lin. Found in the Lakes of Lower Austria, 
and in the Rhine above Constance. 
5. Salmo Salar, Lin. The true salmon. The Salmo Hamatus 
of Cuvier is the old fish, and the Salmo Gadenz of Bloch is the 
young fish. Found in the northern seas, whence it ascends the riv- 
ers, even as faras the Swiss lakes. 
6. Salmo Hucho, Lin. Of the same species as the preceding : 
peculiar to the waters of the Danube. 
The different species of the salmon family are very widely dis- 
tributed ; they thrive in all climates; at least, at all elevations above 
the ocean, whether in fresh water or salt, but they prefer limpid 
water. : 
Sept. 11.—New work on Vertebral Animals.—Prof. Jameson 
exhibited a splendid collection of colored drawings of the vertebrate 
animals of Great Britain and Ireland, by Mr. William Macgillivray ; 
they combined beauty and accuracy ; and form a part of a great col- 
lection, intended for publication, under the title of The Mammalia, 
Birds, Reptiles, and Fishes of Great Britain and Ireland. 
Propagation of Scottish Zoophytes.—Mr. Graham Dalzell read 
a very valuable paper on the propagation of Scottish Zoophytes. 
We have not room even for an intelligible abridgment of the ab- 
stract of this important paper, and can mention only a few facts. 
1. The actinia equina produced over two hundred and seventy 
six young in six years; the embryos first appear on the tips of the 
tentacula, one of which being removed with its embryo began to 
breed in fourteen months, and survived five years. 
2. The Hydra tuba, or trumpet polypus, a new Scottish species ; 
about two inches in diameter; it waves its long white tentacula in 
the water, propagates by an external shapeless bud, and in thirteen 
months gave eighty three descendants ; the group was watched five 
years. 
3. The Tubularia indivisa is rooted to rocks and shells by a stalk 
above one foot high, with a scarlet head, like a beautiful flower: it is 
full of tentacula. Splendid groups occur of fifty or evenone hun-
