14. Notropis eeneolus Hay. 



Four specimeus of this species were collected in the Saliue, of Nvhich 

 one 31: inches long is made the tj'pe of the species. 



15. Pimephales promelas confertus (Grd.) Gilbert. 



16. Pimephales notatus (Raf.) BlatcLley. 



17. Hybognathus nuchalis Ag. 



A number of good specimens of this widely-distributed species were 

 obtained. One of these has a total length of 4i inches. These speci- 

 mens appear to be somewhat more elongated than usual, the head and 

 the greatest depth being each contained in the length to the caudal base 

 5 times. Eye small, its diameter in the length of the head 43, and 

 less than the snout. Scales G-40-5. D. I, 8. A. I, 8. The dorsal is 

 apparently more anterior than in specimens so far described, a perpen- 

 dicular from the insertion of the ventrals leaving two-thirds of the dor- 

 sal base in front of it. Vertebral streak indistinct. One specimen has 

 on the right pharyngeal 8 teeth, all of the same size. Four of these 

 occupy the usual position ; 3 form an inner row ; while the remaining 

 tooth stands outside of, but close against, the row of four teeth. On the 

 left pharyngeal there are 6 teeth, the usual row of 4, then at each end 

 of this row, but placed somewhat further out, another tooth. A hole in 

 the bone midway between these two supernumerary teeth indicates that 

 a seventh tooth has recently dropped or been broken off. Such an ab- 

 normal increase in the number of pharyngeal teeth has now and then 

 been observed in other species, and it appears to occur in both pharyn- 

 geals at the same time. It is not at all unlikely that the genus Tirodon 

 (Hay, Bull. U. S. Fish Com. 1882, 68) was founded on a specimen of 

 this same species with an abnormal number of teeth. 



18. Campostoma anomalum Ag. 



19. Catostomus teres (Mitch.) Glinth. 



20. Ictiobus velifer (Raf.) J. & M. 



Characters essentially those of the specimens collected at Concordia. 



21. IctaluruB punctatus (Raf.) Jor. 



22. Amiurus melas (Raf.) J. & Coiiel. 

 Common. 



VI.— Smoky Hlll Eiver, Wallace, Wallace County. 



The Smoky Hill Eiver at Wallace is much like the Saline at Wa 

 Keeney, but smaller and more rapid. At a point within two miles from 

 the railroad station the stream has been dammed, in order to furnish 

 a supply of water for the railroad tanks, to which it is forced through 

 pipes. Above this dam, where the water is several feet deep, we se- 

 cured the greater part of our collection. Nineteen species are enumer- 

 ated.
