 flap usually pale. Dorsal spines rather low. Color olive; 

 belly largely orange red; scales on the sides with reddish

 1. 47. L. 8 inches. 



This handsome Sun-fish is found in all ponds and streams 

 east of the Alleghanies from Maine to Florida. It reaches a 

 length of eight to ten inches, and is a pan-fish and a game- 

 fish not to be despised. In Virginia and the Carolinas, it is 

 the most abundant of the Sun-fish, and thrives wonderfully 

 in millponds.

 somewhat more; mouth quite small, the maxillary not reach-
