LEPOMIS — SUNFISHES 



257 



It ranges widely throughout the Mississippi Valley, from 

 Minnesota 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.
