62 BULLETIN OF THE UNITED STATES FISH COMMISSION. 



The ventral fins are white, the pectorals and anals nearly white. The 

 dorsals and the caudal are ornamented with narrow dusky bars, which 

 run transversely to the fin-rays. In life there is a scarlet band running 

 along near the upper edge of the spinous dorsal. 



The specimen from which the above description is taken has a total 

 length of two inches. It was seined from a shallow pool along the Big 

 Black Eiver, near Vaughan's Station, Yazoo County, Mississippi, on the 

 20th of August. 



In the collection of fishes made at Memphis is another and smaller 

 specimen of this species, the colors of which are arranged according 

 to a more definite pattern. The square olive blotches along the back 

 are more distinct. From each of the anterior five or six there is a nar- 

 row band of the same color running downward and forward to the 

 ventral region. On the posterior half of the body there are five or six 

 bands, somewhat broader than the oblique ones just mentioned, that 

 alternate with the dorsal blotches and run directly downward. 



9. Vaillantia oamura (Forbes) Jor. 



Boleosoma camurum, Forbes, S. A. Bull. No. 2, Ills. Lab. N.at. Hist., 1878, 40. 

 Vaillantia camura, Jordan, D. S. Bull. U. S. Nat. Mus., No. 12, 89. 

 Vaillantia chlorosoma, Hay, O. P. Proc. U. S. Nat. Mus., iii, 1880, 495. 



One specimen of this species was obtained at Memphis, Tenn., and 

 another at Jackson, Miss. 



It now appears to be highly probable that the specimens that I de- 

 scribed as V. chlorosoma, from Eastern Mississippi, belong to Professor 

 Forbes's Boleosoma camurum, found in Illinois. 



10. Microperca praeliaria Hay. — Southern Least Darter. 



This species was originally described from a single specimen seined 

 at Corinth, Miss. On my last trip I succeeded in getting additional 

 specimens at Memphis, from the Big Black at Edwards, and from the 

 Pearl at Jackson. It therefore appears to be a common and rather 

 widely-diffused species. It is known also from Alabama. The char- 

 acters assigned the species in the original description hold good in 

 the case of the new materials, except that my last specimens all have 

 two anal spines instead of one, as in the type. Two are probably the 



normal number. 



LABEACID.E. 



11. Morone interrupta Gill. — Brassy Bass. 



Two small specimens of this fish were secured at Memphis. It is re- 

 ported to be a very common fish at some seasons, and to be very highly 

 prized for food. 



CEXTEAKCntDiE. 



12. Pomoxys sparoides (Lac.) Grd. — Grass Bass. 



Abundant specimens were captured at Memphis, Yicksburg, Edwards, 

 Yaughan's, and Grenada.
