***Lateral line on 20 to 30 scales. 



I Head 3| in length ; lateral line not to end of first dorsal : scales 

 smallest, 60 in lat. 1. : D. IX or X — 9 or 10. Body fusiform, elongated, 

 caudal peduncle notably much elongated : size large, life coloration bril- 

 liant. Northern Illinois and Wisconsin, eon {Jordan), 3Jss. 



ttHead 3; in length : lateral line variously incomplete ; scales rather 

 large, in 45 to 50 transverse series, D. IX or X — 12 to 14 , caudal peduncle 

 not elongate : body very short and chubby : size small ; colors dull. 

 Georgia to Texas. elegans (Grd.) 



|tt Head 4 in length : lateral line extends to origin of second dorsal ; 56 

 transverse series of scales : D. X or XI — 10 or 11. South Carolina.

 exih'.'t : scales smaller ; first dorsal with a band of vertically elongated 

 black spots : DIX — 11, A II, 9. Cannon Ball R. warreni {Grd.). 



Gen ax FleurolepUy Ay. 

 9. P. jjeUucidisy Ag. Sand Darter. Found sparingly in clear sandy 

 tributaries of the Wabash and Ohio. {Jordan.) 



Genus Boleosoma, DeK. 



10. B. olmsfedi, (^(or.) Ag. Tessellated Darter. Specimens are in 

 the collection from various localities, and Prof. Forbes informs me that he 

 has found it common in all clear streams. Some specimens from Fox River 

 in Wisconsin show characters exactly intermediate between this and the 

 atromacidata of Girard. Other specimens from the Fox River at Geneva, 

 111., agree with the description of atromacu/ata, and others from the same 

 locality answer perfectly to olmMedi. 



11. B. brevipiune. Cope. Slim Darter. Apparently everywhere com- 

 mon in clear streams throughout the state. 



Genus Etheostoma, Raf, 



12. E. hlennioidtfi, Klrt. Black-sided Darter. Rather common in the 

 Wabash valley. 



13. E. pho.cocepkaluin, sp. nor. This species replaces the preceding 

 in the western part of the state, and from the number of specimens in 

 the collection and the localities represented, appears to be rather common 

 in the Illinois and its tributaries. 



^^p. Char. Head about 4 times m total length ; depth 61 : eyezzzsnout, 

 4j in head : D. XIII — 12. A. II, 8. Lat. 1. 76. Inter-orbital space more 

 than 6 in head. Cheeks naked; opercles .scaly, breast naked. Middle 

 line of belly with line of larger scales or a naked strip. Pectorals shorter 

 than head. Fins mottled : sides with a lateral band of small «quarish spots 

 usually connected by a narrow black line. A black .spot at base of caudal 

 and one at base of lateral line. 



Back mottled and tesselated with dark on a light ground. A black 

 line from eye forward and another downward. This species bears a super- 

 ficial likeness to E. blennioides, but may be distinguished at once by the
