252 SAMLET, OR PARR. 



narrow, tlie snout pointed, and the caudal fin acutely forked; 

 the body of the Parr is thick and clumsy, the snout broad and 

 blunt, and the caudal fin much less forked. The operculum of 

 the Salmon is beautifully rounded at its posterior margin, with 

 the basal line of union with the suboperculum much curved; 

 in the Parr this part is rather produced, with the line of union 

 nearly straight. In the Salmon the maxillary is short and 

 narrow; in the Parr it is longer and broader, particularly at 

 the posterior free extremity. The teeth of the Salmon are long 

 and fine, when recent easily bent; those of the Parr are shorter 

 and stouter, and resist much pressure. In the Salmon the 

 pectoral fin is short, not quite one seventh part the length of 

 the whole fish, with the fourth ray the longest; the same fin 

 in the Parr is very long, not quite one sixth part the length 

 of the whole fish, with the fifth ray the longest, giving a form 

 to the fin totally diflPerent from that of the Salmon." Other 

 marks, less decisive, are given, but it is important that "the 

 bones of the Salmon are rather soft;" in the Parr "the bones 

 are stout and hard." "No instance is yet known of the Parr's 

 being taken in the sea, nor does it appear to me to be so 

 common a fish as is generally considered."
