CENTRARCHID^B. 83 



Milan, Sandusky Bay, Wabash river at Celina, R. C. Osburn,

 abundant; Pippin lake, Chippewa lake, Summit lake, Ohio river 

 at Bellaire, R. C. Osburn, 1900.

Eupomotis heros (Baird and Girard). 



Head 1% to 3; depth 2 to 2f ; eye 3^ to 4^; snout 5% to 4. D. X, 11; 

 A. Ill, 11; scales 4-34 to 39-13, 4 rows on cheek. Appearance of Lepomis 

 pallidus. Body robust, moderately elongate, dorsal and ventral outlines 

 about equally curved. Head rather large, a considerable depression in pro- 

 file above eye; mouth rather large, maxillary reaching past front of eye. 

 Dorsal spines rather high; pectorals reaching beyond middle of anal. 

 Opercular flap smaller than eye, much as in E. gibbosus. Pharyngeal teeth 

 not so blunt as in gibbosus. Color dark greenish above, gradually becoming 

 brassy on belly; opercular spot greenish black, the flap with a broad, blood- 

 red border in male, plain in females. No spot on dorsal or anal. Length

This is a species of southern distribution, and in Ohio prob- 

 ably occurs only in the southwestern part of the state. It has 

 been recorded, in 1888, for the L,ittle Miami river in Hamilton 

 County, by Henshall, under the name Lepomis notatus.
