SPECIFIC DESCRIPTIONS. 



MICROPTERUS NIGRICANS Nelson, 1876. "Found in great 

 abundance throughout the state [Illinois], as far as I can learn. 

 The young are found in myriads in the ditches draining the 

 marshes along the Calumet river." (NELSON, Cat. Fishes Ills. 

 <CBi*tt. Ilk. State Lab. Nat. Hist., i, 36, 1876.) 



MICROPTERUS PALLIDUS Hay, 1880. "This species is abun- 

 dant every-where [in Mississippi], and is esteemed as one of the 

 best food fishes. It is called " Trout," instead of " Bass," as at 

 the North. The young are conspicuously marked by a dark, 

 sometimes interrupted, lateral band. This is sometimes found 

 also in the adults. There is often a small patch of feeble teeth 

 on the tongue of both this species and M. salmoides [M. dolomieu~\." 

 -(HAY, Pro. U. S. Nat. Mus., iii, 497, 1880.) 



MICROPTERUS FLORIDANUS Cope, 1880. "It appears then, 

 that the only important character which distinguishes the Texan 

 form from the Floridian is the much smaller size of the cheek 

 scales. I do not know how constant this character will prove.
