 common trout, and pointed at the upper and lower extremities, whilst 

 in the latter they are rounded. Teeth stout, sharp, and curved slightly 

 inwards, situated as in common trout. Scales small, thick, and adherent, 

 and, when dry, exhibiting a small ridge in the centre of each, not per- 

 ceived in the common trout, viz., in an oblique line between the middle 

 back fin, say to lateral line. Colours : Back, deep olive green ; sides, 

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

 grey ; back and tail fins, dusky ; ventral and anal fins lighter.
