and the other two, togue and siscowet, consists in the ven- 
tral fin being placed farther back on the former, and the tail 
being more forked. They have also a double row of teeth, 
extending a half inch backward on the vomer. The teeth, 
gums, and roof of mouth have a tinge of purple, hence Mitch- 
ell’s name, ‘amethystine salmon.’ ”—A. Lerru Apams, M.A.,

Tue Siscowet.—Salmo siscowet, Agassiz. 
The siscowet is known by this native name, apparently 
in contradistinction to the namayeush, both being found in 
Lake Superior. This fish is said to be plentiful about Isle 
Royal —a large island near the north-west shore of Lake 
Superior. Agassiz gives this fish the following distinctive 
characters: The lower branch of the pre-operculum, @, is 
more extended than the upper, 6. The pectoral fin, ¢, is 
longer, and farther from the gill opening than in either the 
other trouts; and the dorsal, d, is said to be larger, with a 
more slender and less elub-shaped adipose fin,e. The anal, 
J, is as long as the dorsal, but not so wide. 
The cisco, or ciscoquette, of page 293, as a congener of 
the lake herring, is a mere clupea, while the siscowet is the 
nearest approach to the real salmon of any lake trout. The 
following extracts by our learned friend C (who favored 
me with notes on Florida fishes), will be found interesting 
to disciples of the gentle wand, and I give them as follows: 
“You mention the cisco, and it appears that you may have 
confounded it with the siscowet, which is a good salmon, 
having all the marks of that family, while the cisco is a
