 total length, is as one to four and a half. The upper javv^ slightly the longest. Lateral line 

 slightly concave under the dorsal fin, and then straight. Breadth of the head slightly less 

 than its length. Eyes small, two-tenths of an inch in diameter, and far apart. Nostrils

 anterior margins ; the anterior pair subtubular, and near the edge of the jaws. A long cirrus, 

 stout and fleshy at its base, at each angle of the jaws, and an inch and a half long. A pair 

 of slender cirri 0*6 long, on the summit of the head; four others under the lower jaw, 

 arranged in a curved line an inch in extent; the internal pair shortest, and all slender. 

 Humeral bone with a blunt spine over the pectoral, and a short obtuse angular projection 

 beneath. Mouth very ample and dilatable. A band of small recurved teeth in each jaw, 

 broadest in the centre, and diminishing to a point on the sides. Vomer and palatines smooth.

 a few scattering minute teeth. 



The dorsal fin commences half an inch posterior to a point vertical to the origin of the pec-

This is very common in Lake Pleasant, Lake Janet, and many of the other lakes in the 

 northern districts of the State. There are many varielies in its markings, and it occasionally 

 exceeds a foot in length. Its principal use in those regions appears to be, to serve as bait for 

 the lake trout.
