!olor, in alcohol, dark brown above : sides with a silvery luster; belly 



Li; body everywhere finely punctulate with dark dots; these extend 



the vertical fins, which otherwise are entirely plain. Xo black spot 



)ase of dorsal nor elsewhere on the fin. 



his description is drawn from six specimens, varying in length from 



to 2^ inches. They were collected in a tributary of the Alabama 



er, at Montgomery, Alabama, by Col. M. McDonald, of the U. S. Fish 



nmission. 



'his species is closely related to N'otropis ardens, punctulatus, and 



ers constituting the subgenus Lythrurus. The absence of black 



■kings on the dorsal well distinguishes it from most of these.

 THE UNITED STATES NATIONAL MUSEUM. 



By DAVID 8. JORDAN.

Lead, 3f (4|) ; depth, 5|- (Cf). D. VIII, 9 ; A. II, 7. Scales, 4^53-10 ; 

 ■ral line with i)ores on 15 scales. Length (35747, Montreal, Canada), 

 nches. 



lody moderately elongate, somewhat compressed, the caudal pednn- 

 rather long and stout, the general form resembling that of P. artesiw 

 P. punctulatus. Head rather heavy, the snout bluntish, rather 

 >ngly decurved. Anterior i^roflle gently and somewhat evenly 

 lied. Snout short, about half as long as eye, which is 4 in head, 

 nth nearly- horizontal, the lower jaw included, the maxillary ex- 

 ding about to opposite front of ])upil, its length 3| in head. Teeth 

 dl. Preopercle entire. Opercular spine strong, rremaxillary not 

 tractile. Gill membranes very slightly connected. A small black 

 Lieral scale. Cheeks, opercles, and nuchal region scaly; breast naked, 

 les of moderate size. Lateral line very short, not reaching last spine 

 [lorsal, running rather high and slightly arched. Scales of belly 

 s those of the sides. 



)orsal tins well separated, unusually short and small; the longest 

 le in the largest example ( 9 ?) 3i in head, in another one ( 5 ?) 2| 

 lead. Soft dorsal a little higher than spinous dorsal, also unusually 

 ill for this genus. Caudal long, truncate or slightly lunate, 1.^ in 

 d. Anal low and short, its spines high, the first highest. Pectorals
