33. Lepjinis ci/anellas, Kaf. — Red-eye; Blue Spotted Sun-fish. 



(Bal. II, 45 ; Apomotls 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. Chtenobkyttus, Gill. 



39. Chcenobryttus gulosus, C. & V. — WaPiJEouth; Eed-eyed Bream. 



The sun-fish ranges throughout Llinois, but is far the most 

 abundant southward, where it is one i<\ ilie commonest species of 

 its family. Indeed, we lia-ve not onr-^lves taken it north of the 

 IlHnois River, but Dr. Jordan reports specimens received from Lake 

 Michigan. It is essentially a pf>nd spt-cies but occurs also in the 

 larger streams. In the southern part of the State it receives several 

 of the common names (such as Goggle-eye, Red-eye, etc.) appropri 

 ated northward to the Rock-bass. 



Genus 18. Ambloplites, Raf. 



40. Ambloplites rupestris, Raf. — Common Rock-bass ; Red-eye ; 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 the 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 

 creeks to the Illinois River, and is also common in the smaller 

 lakes. 



Genus 19. Pomoxys, Raf. 



Croppies. 



41. Pomoxys sparoides, Lac. Black Croppie ; Calico Bass ; Grass 



Bass; Barfish; Butter Bass. 



(Bui. II, 47 ; Poinoxt/s nigromacu'atus.) 



Found, like the preceding, throughout Illinois, but commonest to 

 the north, occurring in both lakes and streams ; most abundant in 

 the former. 



42. Pomoxys annularis R-if. — Croppie ; Pale Croppie. 



Ranges throughout Illinois from Galena to Cairo. Confined prin- 

 cipally to the larger streams and their immediate tributaries, it be- 

 comes rapidly more almndant as we pass from north to south, 

 finally virtually replacing the preceding species.
