 A single specimen of the "Hog--fisU", talveu from the Chickasawlia, 

 bas been sent me by JMr. AV. A. Warner. 



Genus HADEOPTERUS, Agassiz. 



3. Hadropterus spillmaiii, Hay, sp. iiov. (No. 27,432.) 



Body elongated, compressed. Head in tlie length about 4 times. 

 Depth in the length, e:iclnsive of the c:uidal iin, 5 times. Eye equal to 

 snout, and one-fourth the length of the head. 



Lateral line with from 50 to GO scales, rows above and 9 bq^w. A 

 row of enlarged, non-deciduous, ctenoid plates along the middle of the 

 Jjelly. Cheeks and opercles scaled. The whole chest covered with 

 small plates or scales. 



The fin-rays as follows : D. XII, 12 ; A. II, 9. Si)inous dorsal about 

 nine-tenths as long as the head, and one-half as high as long; soft dor- 

 sal three-fifths as long as the head, and five-sixths as high as long ; anal 

 equal in length to the soft dorsal, and about as high as long. Veutrals 

 and })ectoi-als reaching back about to the same point, two-thirds the dis- 

 tance from the base of the veutrals to the vent. Caudal fin truncated. 

 Spinous and soft dorsals well sei>arated. 



The snout is rather pointed; upper jaw not protractile ; mouth moder- 

 ate, the maxillary reaching back to a vertical from the anterior of the 

 orbit. Teeth on jaws, vomer, and palatines. Mouth slightly oblique. 



The general color is dark above, reddish .yellow below. The sides are 

 crossed by about a dozen brown bands, which are broadest along the 

 lateral line, where coalescing they form a dark horizontal band. This 

 band becomes narrower and better defined on the head, and is contin- 

 ued along the upper edge of the opercle and cheek, through the eye, to 

 the tip of the snout. A narrow dark line runs downward and forward 

 from the lower edge of the orbit. There are three well-defined spots at 

 the base of the caudal fin. 



The vertical fins are blotched more or less with dusky colors; the 

 veutrals are bluish black, while the pectorals are lighter. 



The cheeks and the occipital region are ])ale in color ; the snout and 

 iuterorbital space are bluish black. 



Length, exclusive of caudal fin, o inches. 



This si)ecies is allied to H. nigrofasciatus, a description of which is 

 given by Professor Jordan in the Ann. ]l!^. Y. Lye. Nat. Hist. 1877, 310. 

 Judging from a comparison of my specimens with his description, I 

 think that they evidently belong to a distinct species. 



Several specimens of this handsome fish were caught with small 

 hooks in a branch flowing into the Chickasawha at Enterprise. 1 dedi- 

 cate it to my friend Eev. William Spillman, M. D., of Enterprise, who
