LEPOMIS SUN FISHES 



257 



It ranges widely throughout the Mississippi Valley, from Minne- 

 sota and South Dakota and the Ohio basin generally, to Kansas, 

 Arkansas, and Texas. We find no mention of it from the Atlantic 

 slope. 



Ripe males and females in high coloration, swimming in pairs, 

 were taken by Dr. Kofoid in Meredosia Bay June 8, 1899. The sexes 

 present a notably different appearance in outline as well as in color, 

 the males having the forehead concave, the profile steeper, and the 

 ventrals longer than the females.
