The skin of a fine specimen of this species was obtained at Shubuta, 

 the fish having been hooked from a branch of the Chickasawha. 



Genus NOTUEUS, Eafinesqne. 



55. Noturus leptacanthus ? Jordan. (No. 27,442.) 



Noturm leptacanthus, Jordan, Annals N. Y. Lye. Nat. Hist. 1877, 352 ; Bull.

I have in my collection a specimen of a Noturus "which agrees pretty 

 well with the descriptions given by Professor Jordan of his .W. leptacan- 

 thus, as above cited. There are, however, some important differences 

 which I am not able to acconnt for satisfactorily. My specimen is not 

 quite 2 inches long to the base of the caudal, and is, therefore, most prob- 

 ably a young one. Hence, the differences noted below may be due either 

 to its beiug immature or to its being a different species. It seems that 

 Professor Jordan knew of but a single specimen, and therefore his de- 

 scription may not be applicable to every individual belonging to the 

 species.* 



The head is small and narrow, widening gradually from the narrow 

 snout to the shoulders ; the lateral outlines of the head, therefore, 

 straight ; its length 4i times in the body. Upper jaw projecting, spines 

 rather long and slender, instead of being short as in the type, the pec- 

 toral spine being one-half the length of the head. The color is quite dark. 



In other respects the characters assigned by Professor Jordan to his 

 species aj)ply reasonably well to my specimen. I think, therefore, that 

 until more material is collected it will be better to assign the specimen 

 as above. 



Collected at Enterprise. 



56. Noturus gyrinus (Mitchill) Raf. 



Noturus gyrinus, CoPE, Journ. Acad. Nat. Sci. Phila. 1869, 237. — Jordan, Bull. 

 U. S. Nat. Mus. No. 10, 102. 



Another Noturus, 2 iuches long, collected at Macon, belongs to the 

 above species. 



I append the following list of species collected at each of the localities 



visited : 



1. Corinth. Water flowing toward the Mississippi. 



* Professor Jordan informs me that he has additional specimens of his N. leptacan- 

 thus, in all of which the spines are short, less than one-third the length of the head. 

 The skin, however, is said to bo dark, as in my specimen.
