244 LOCHLEVEN TROUT. 



Scales small and well fixed. Colour of the back deep olive green, 

 the sides lighter, round dark spots on the gill-covers and sides; 

 also on the dorsal fin, none of them with a lighter border. 

 Anterior border of the dorsal and anal fins plain. Compared 

 with the Common Trout, there is a considerable difference in 

 the number of caeca or appendages to the beginning of the 

 bowels, there being from sixty to eighty in this fish, and only 

 about forty-six in the Common Trout ; and it is on this account 

 that the specific name of ccecifer, or cceca-bearer was bestowed 

 upon it. But there are other, and striking differences between 

 this fish and the Common Trout, as that the pectoral fins are 

 pointed, those of the latter fish rounded; the body without red 

 spots. In the Lochleven Trout the rays of the tail are propor- 

 tionally much the longest, and the upper and lower portions 

 more pointed. Colour of the flesh deep red.
