Back's Grayling.
(p. 713)"This beautiful fish inhabits strong rapids. Its stomach is generally filled with
gravel, or black earth. It bites eagerly at the artificial fly, and, deriving great power
from its large dorsal fin, affords much sport to the angler. Its rectum is filled with
black fæces. The ordinary length of the species is about sixteen inches, exclusive of
the caudal fin, or about twelve inches from the snout to the anus. As an article of
food it is inferior to the attihhawmegh. It is found only in the clear rivers to the
northward of Great Slave Lake.
In the figure, which is an accurate representation of the dried specimen, the pos-terior
part of the fin is scarcely produced enough, owing to a portion of it having broken
off in the carriage."
