The skin of a fine specimen of this species was obtained at Shubuta, 
the fish having been hooked from a branch of the Chickasawha.

J have in my collection a specimen of a Notwrus which agrees pretty 
well with the descriptions given by Professor Jordan of his WV. leptacan- 
thus, as above cited. There are, however, some important differences 
which I am not able to account 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 being 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 41 timesin 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 apply 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.

U.S. Nat. Mus. No. 10, 102. 
Another Noturus, 2 inches long, collected at Macon, belongs to the 
above species. 
I append the following list of species collected at each of the localities 
visited : 
1. Corinto. Water flowing toward the Mississippi. 
1. Vaillantia chlorosoma. 5. Luxilus cornutus. 
2. Microperea preeliaris. 6. Minnilus punctulatus. 
3. Zygonectes notatus. 7. Notemigonus chrysoleucus. 
4. Hyborhynchus notatus. | 8. Erimyzon sucetta. 
* Professor Jordan informs me that he has additional specimens of his V. leptacan- 
thus, in allof which the spines are short, less than one-third the length of the head. 
The skin, however, is said to be dark, as in my specimen.
