88. Lepomis cyanellus, Raf.—Rep-EyvE; Buur SporreD SUN-FISH. 
(Bul. II, 45; Apomotis cyanellus.) 
This is the most abundant sun-fish of the small prairie streams 
and pools of Central Illinois, where, in fact, it is almost the only 
species occurring. It ranges throughout the State, from Cook to 
Union county, occurring in relatively small numbers in the rivers, 
but superabundantly in creeks and ponds. 
Genus 17. CHmNosBrytTtus, Gill. 
39. Chenobryttus gulosus, C. & V.—WarmoutH; Rep-ryvep Bream. 
This sun-fish ranges throughout Illinois, but is far the most 
abundant southward, where it is one of the commonest species of 
its family. Indeed, we have not ourselves taken it north of the 
Illinois River, but Dr. Jordan reports specimens received from Lake 
Michigan. It is essentially a pond species, but occurs also in the 
larger streams. In the southern part of the State it receives sev- 
eral of the common names (such as Goggle-eye, Red-eye, etc.,) ap- 
propriated northward to the Rock-bass. 
Genus 18. AmsBuiopuitses, Raf. 
40. Ambloplites rupestris, Raf.—Common MRocx-Bass;  Rep-rEyz; 
GOGGLE-EYE. 
Quite common northward, but relatively rare in Southern Illinois, 
where, indeed, we have not yet taken it. As its southern range, 
however, is said to extend to Louisiana, it probably occurs occa- 
sionally in the southern part of this State, and is reported by fish- 
ermen to be common in the rapids of the Wabash. In Northern 
and Central [Illinois it is found in streams of all sizes, from small 
— to the Illinois River, and is also common in the smaller 
akes. 
Genus 19. Pomoxys, Raf. 
CROPPIES. 
41. Pomoxys sparoides, Lac. Buack Cropriz; Catico Bass; Grass 
Bass; BarrisH; Butrrer Bass. 
(Bul. Il, 47; Pomoxys nigromaculatus.) 
Found, like the preceding, throughout Illinois, but commonest to 
the north, occurring in both lakes and streams; most abundant in 
the former. 
42. Pomoxys annuluris Raf.—Cropriz; Pate Croprie. 
Ranges throughout Illinois from Galena to Cairo. Confined prin- 
cipally to the larger streams and their immediate tributaries, it 
becomes rapidly more abundant as we pass from north to south, 
finally virtually replacing the preceding species.
