base of caudal. Pectoral four-sevenths of space to ventral. Ven- 
tral inserted a little behind dorsal. Caudal slightly lunate. Dark 
olive above. Sides with many red spots, usually smaller than 
pupil. Back more or less barred or mottled with shade darker 
than ground-color. Dorsal and caudal barred or mottled with 
darker. Lower fins dusky with edges anteriorly orange followed

A beautiful fish, of clear cold streams and best suited to the 
northern counties, and the chief object of pursuit to the true 
angler. Its beauty and combined characters of excellence as 
both a table-fish and game-fish have led to its imtroduction into 
streams not originally stocked.

fourth. Branchiostegals five to ten. Stomach a blind sac with 
pyloric cceca few or none. Air-vessel single, large. Ova large, 
falling into cavity of abdomen before extrusion. Body covered 
with moderate or small scales which are usually cycloid. Head

Small marine or anadromous fishes, some in deep water mostly

cate and valuable food-fishes. A single species in our waters.
