THE SALMON FAMILY. 



341 



were 32 in the upper jaw, 18 on the lower, 12 on each palatine 

 bone, 13 on the vomer, or central bone in roof of mouth, and 8 on the 

 tongue. Scales small, thick, and adherent, when dry exhibiting a 

 small ridge in the centre of each, not perceived in the Common Trout; 

 24 in an oblique row between middle back-fin ray and lateral line. 

 Pyloric caeca from 60 to 80. Colours : back deep olive-green ; sides 

 lighter j belly inclining to yellow ; pectoral fins orange, tipped with 

 grey ; back- and tail-fins dusky ; ventral and anal fins lighter. Gill- 

 cover (in the specimen described by Dr. Parnell) with 9 round dark 

 spots ; body above lateral line with 70 spots, below it 10 ; back -fin 

 thickly marked with similar spots. Forward extremities of anal and 

 back-fins without the oblique dark bands so constant and conspicuous 

 in many of the Common Trout. Flesh deep red. The Lochleven Trout 

 has never any red spots, and the Common Trout is scarcely ever with- 

 out them (see also p. 314). It is probable that the Lochleven Trout is 

 identical with the Fario Lemanus of the Lake of Geneva.
