SAMLF.T, OR PARR.

throat; not so stout as we find them in the Trout; but to 
confirm the opinion here expressed, of the distinction between 
the Samlet and the Trout, which may be again doubted, we 
quote Sir William Jardine’s remarks from the new “Edinburgh 
Philosophical Journal,” January, 1835. Speaking of the uncer- 
tainty attending the nature of this fish, he says it has latterly 
resolved itself into whether it was distinct or a variety or young 
of the Common Trout, (S. fario;) “with the migratory Salmon 
it has no connection whatever.” 
The forehead of the Parr is shorter than that of the Trout, 
the gape less, under jaw weaker, teeth finer, as is particularly 
seen on the tongue, round the palate, and along the vomer. In 
the fore part of this last-named bone the double line of teeth 
is more separated, or in a loop. The pectoral fin is longer 
and more full, the adipose fin differently shaped, and without 
the bright red border seen in Trouts. The first dorsal fin 
plain, with a dark border in front, without a light margin; 
anal fin plain, without the light-coloured border as in the 
Trout. Some examples have spots on the first dorsal fin; the 
red spots on the body are not surrounded with a pale ring, 
and they are fewer in number than in the Trout; none below 
the lateral line, along which they run at regular distances. 
The lateral bands vary a little in dilferent specimens, but in 
all they differ from those of the Trout. They communicate 
with the colour of the back in all their breadth, but the deepest 
tint is low on the side, contrary to the habit of the Trout, in 
which they gradually grow fainter; nor is it usual with the 
Trout to retain any bands at so late a period of its growth. 
In a few of these particulars, the comparison with the Trout 
in its varieties as found in different rivers is scarcely borne 
out; but in most of them the difference appears equally great 
as laid by the side of a Salmon of equal size, and the comparison 
of the bands of colour is especially appropriate. 
In confirmation of this we refer to the additional authority 
of Dr. Parnell, in his essay on the fishes of the district of the 
Forth, in the seventh volume of the Memoirs of the Wernerian 
Society: — “If,” says he, “we compare a young Salmon of eight 
inches in length with a Parr of equal size, both taken from the 
same river in the month of May, we shall find them to differ 
in the following respects: — The form of the Salmon is long and
