THE LESSEE LAKE TROUT. 



Salmo Adirondakus : NOBIS. 



This, the Lake Trout of Hamilton and Franklin counties,

This fish, in form, is oblong ; head one-fourth its length ; 

 upper jaw slightly longer ; no scales on opercles ; eye one-

 mottled rather than spotted ; branchial rays 12 ; dorsal 1*10 ; 

 pectorals 13 ; ventral 9 ; anal 2'10 ; caudal (forked) 3'22, 8. 

 There are two rows of teeth on each side of the roof of the
