longest; all the rays except the first branched: ventrals in a line with 

 the "commencement of the dorsal, about equal to the pectorals, rounded ;

B. 3 '; D. 12 ; A. 13 ; C. 19, and 4 or 6 short ones ; P. 16 ; V. 9.

Common in lakes and still deep rivers throughout the country. Keeps 

 in large shoals. Usual weight from a pound to a pound and a half: 

 sometimes, however, exceeding two, or even three, pounds. Spawns in

LENGTH. That of the specimen described below was six inches and 

 a half: gets to a larger size. 



DESCRIPT. (Form.) "Body slender in proportion to its length: the 

 head, compared with the length of the head and body alone, without 

 the caudal rays, as two to nine : depth of the body equal to the length 

 of the head : diameter of the eye compared with the length of the head 

 as two to seven : nose rather rounded : upper jaw longest: the ascending 

 line of the nape and back more convex than any other portion of the 

 dorsal or abdominal line : the first ray of the dorsal fin arising half-way 

 between the anterior edge of the orbit of the eye, and the edge of the 

 fleshy portion of the tail ; the first ray half as long as the second, which 

 is the longest, and is as long again as the last ray of this fin, the length 

 of the last ray being equal to the length of the base of the fin : the pec- 

 toral fin rather long and narrow: ventrals arising just in advance of the 

 line of the origin of the first ray of the dorsal fin ; the distance from the 

 origin of the ventrals to the origin of the anal fin, and from the origin of 

 the last ray of the anal fin to the end of the fleshy portion of the tail, 

 equal ; the first ray of the anal fin nearly as long again as the last : tail 

 considerably forked, the external rays being as long again as those in the 

 centre : scales of the body moderate in size, fifty forming the lateral line, 

 with an oblique row of seven scales above it under the dorsal fin, and four 

 below it ; the lateral line itself concave to the dorsal line throughout its 

 whole length.
