SAMLET, OR PARll. 251 



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 diflTerently 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 tin 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 different 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 

 M'hich 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 ]\Iay, we shall find them to differ 

 in the following respects: — The form of the Salmon is long and
