JUNE, 1896. ON SOME COLLECTIONS OF FISHES HAY. 93 



'nearer to the adipose fin. Cases such as are described above are well 

 adapted to arouse doubts as to the distinctness of the species natalis 

 and nebulosus. 



7. Ictiobus cyprinella (C. & K). RED-MOUTHED BUFFALO. 



A single individual was procured. It is a common fish in the river. 



8. Ictiobus bubalus (Raf.). SMALL-MOUTHED BUFFALO. 



Two specimens. 



9. Cliola vigilax (B. 6 G.}. 



Three specimens were obtained. This species ranges from 

 northern Indiana to southern Mississippi. 



10. Notropis heterodon (Cope). 



Eight specimens were secured. I have observed no differences 

 between them and the specimens from the Kankakee River. The 

 teeth of such as were examined were 2, 4 4, 2. The largest indi- 

 vidual, 2 inches long, has a very distinct dark lateral band. The 

 smaller ones, i^ inch, are paler, with the lateral band indistinct, but 

 with a conspicuous tail-spot. 



11. Notropis lutrensis (B. 6 G.). 



Seventeen specimens of this fine minnow were obtained. It is a 

 very common little fish in the streams of Kansas and southward to 

 the Rio Grande. It was found some years ago in southern Illinois, 

 and was described by Dr. Jordan (Bull. 111. Lab. Nat. Hist., Vol. II, 

 p. 57, 1878) under the name of Cyprinella forbesi. Its discovery at 

 Havana extends considerably northward its published range. 



12. Notropis umbratilis (Girard}. 



Nine specimens. This is another species whose center of distri- 

 bution lies toward the west and southwest. It had, however, been 

 previously found in the State and described by Dr. S. A. Forbes, 

 under the name of Notropis macrolepidotus. Although the Illinois 

 specimens show some differences when compared with those from 

 further west, they are probably not distinct. Those secured by me 

 are small. Scales of the lateral line 40, of which 20 lie before the 

 dorsal fin; anal rays 10; a dusky dorsal line made up of black specks; 

 a lateral band of similar specks, the band being broadest and most 

 distinct behind. 



13. Phenacobius mirabilis (Girard). 



Four specimens are in the collection. This species had been
