gulosus (Ouvier & Valenciennes) and Lepomis gib- 

 bosus (Linnaeus). At the time of capture it was 

 noted that the form and color were unusual and 

 unlike any of the Centrarchids common to these 

 waters. 



Following is a table of comparative measure- 

 ments of the hybrid and a typical example of each 

 of the other species of nearly the same size :

The profile of the hybrid is very different from 

 C. gulosus, the body being short and deep, ovate ; 

 the snout is long, pointed, and the upper profile, 

 from tip of snout to origin of dorsal, is relatively 

 straight. 



In C. gulosus the pectoral is broad, distal mar- 

 gin evenly rounded; in the hybrid, it is broad, 

 pointed, upper rays longest, and in L. gibbosus it is 

 narrow, pointed, median rays longest, Although 

 the color pattern of the hybrid is nearest to that of 

 C. gulosus, it is unlike that of any example seen in 

 these waters, the color markings are less distinct
