The vertical bands which are rejiresented as brown in the above figure, 

 are a beautiful turquoise blue in life.

A veiy marked variety, perhaps species, represented by three specimens 

 from the upper waters of the Catawba River, N. Ca. Scales much larger 

 than in the types, 6 — 42-4 — 9-10 ; in the only adult there are but four ver- 

 tical cross-bars below the dorsal fins, (six to eight in the usual variety) 

 and the fin formula is much reduced, i. e. DVI-12 A II. 6. In a younger 

 specimen the D.VII-12 A II.8, and in a third, D.VIII-12 A II. 7.6. The 

 dorsal and lateral spots are more numerous than in the adult. Head in 

 the latter 3.5 times in length to caudal. In other respects this form is 

 like the type, except that in life the colors are paler.

Spec. nov. 



This species is very unlike the others of the genus, having the cylindric 

 form of Percina and Pleurolepis ; it further resembles Pleurolepis pellu- 

 cidtis in the transparency of its muscles, but is to be referred to another 

 genus on account of the reduction of its anal fin, and its complete scutel- 

 lation. 



The head is remarkably acuminate, the profile gradually descending 

 and the under jaw received within the'upper ; the mouth is nearly termi- 

 nal, and the extremity of the maxillary bone reaches barely to the line of 

 the anterior margin of the orbit. Both cheeks and operculum are cov- 

 ered with large pectinated scales, the former as far as the preopercular 

 bone. Opercular spine rudimental, flat, as in some individuals of P, flab- 

 ellatus. The orbit is relatively small, its diameter being less than the 

 length of the muzzle in advance of it, and a half less than one-fourth the 

 length of the head. Depth of head at deepest point, one-half its length ; 

 its length 4.5 times in length of body to basis of caudal. The fins are 

 not largely developed, except the pectoral, which is very long and acu- 

 minate, reaching the line of the vent. Br. VI. D. VII-14. A II.9. Ven- 

 trals cuneiform, a little over half the length of the pectorals. Caudal 

 nearly equal or slightly concave. Scales 6—56—7, counted from the ante^ 

 rior ray of the second dorsal to the vent. Oit the anterior half of the dor-
