NOMENCLATURE AND MORPHOLOGY. 21 



swifter water than the preceding [other] species. It occurs 

 throughout Illinois, but is relatively rare to the southward. Has 

 heen takeu by us iu the Wabash and some other of its larger 

 tributaries, but not elsewhere south of the Illiuois river." —

MiCROPTERUS DOLOMiEU Gill, 1885. — "The small-mouthed 

 Black Bass has the mouth comparatively small, aud the maxillaiy 

 of the adult does not extend beyond the orbit ; the scales are con- 

 siderably smaller, there being seventy-two to seventy-five along 

 the lateral line, aud as many as ten or twelve rows between the 

 lateral lint aud back. It does not extend north of the region of 

 the great lakes, and is not known to reach farther south than 

 South Carolina and Arkansas. In most places it is associated 

 with the large-mouthed species. It does not, as a rule, reach as 

 large a size as its relative." — (Gjll, Standard Nat. Hist., vol. iii, 

 231, 1885.) 



MiCROPTERUS DOLOMIEU Mather, 1886. — "The small-mouth 

 was introduced into Brown's tract inlet, flowing into Racquette 

 lake, some yeai's ago, by the New York Fish Commission, aud 

 now they are plentiful in the lake aud are working down into 

 Forked lake and toward Long lake. . . . There is a preva- 

 lent theory that. this species is 'gamier' than its cousin, the big- 

 mouth or ' Oswego' Bass, an opinion that I am not prepared to 

 indorse, as I have found but little difference between them when 

 both were under two pounds weight." — (Mather, Colviu's Adi- 

 rond. Surv., Fi.<hes, 5, 1886.) 



MiCROPTERUS DOLOMIEU Jordan and Evermanu, 1886. — • 

 " This species is usually placed first among the game fishes of 

 the state. It frequents clear waters, especially those with some 

 current, and is averse to mud. It is much less frequently found 

 in ponds than the large-mouthed Bass." — (Jordan and Ever- 

 MANX, Ind. Ar/ric. Report, 13, 1886.)
