which I brietly de^criliL'd the specimen and compared it with Feix-ina 

 eaprodes and lladropterus aspro. Last summer the sandbars on the 

 south side of the east end of the hilce were again extensively seined and 

 among some 500 or GOO Percina eaprodes two small specimens — probably 

 that summer's brood — Avere taken which, bej'ond a doubt, are similar to 

 the specimen which had been taken six years previously in a part of the 

 lake three or four miles distant. Among a peck of darters from a part of 

 Tippecanoe Lake that the labels do not indicate, collected in 1898 by some 

 students of the Indiana University Biological Station, I found three simi- 

 lar specimens, making in all six specimens of this type from different 

 parts of the lake. There can no longer be any doubt that we have to do 

 with a distinct species and, so far as I can determine, the species is un- 

 described. This new species is among the most beautiful and largest of 

 the darters. It gives me the greatest pleasure to name the species for Dr. 

 Barton Warren Evermann, icthyologist, of the U. S'. Fish Commission.

Head 4; depth (J.IC; I>. XVL 14; A. IT, 11; scales S— 7!)-!>. 



The form of the body is mucli like that of 11. (ispm. rather elongate, 

 fusiform, somewhat compressed posteriorly. l)ut less pointed anteriorly. 

 Mouth moderately large, maxillary reaching to the pupil; the cleft of 

 mouth almost horizontal, lower jaw iucluded; eye large, about equaling 

 snout; interorbital rather broad, fiat; gill membranes free from isthmus 

 and separate; opercular spine and flap well developed; preopercle entire. 



All scales ctenoid; nape witli fewer, smaller, embedded scales; median 

 ventral line in one specimen provided with a row of closely set, slightly 

 enlarged scales, a second specimen has three or four such scales, the re- 

 maining specimens are without scales; the breast naked; opercle with 

 closely set ctenoid scales slightly smaller than those on the body; cheeks 

 with fewer still smaller, embedded ctenoid scales; lateral line complete, 

 slightly arched over pectorals. 



Pectoral and ventral fins about ecjual in length, measuring one and 

 one-third in head; origin of spinous dorsal one-third the distance between 

 the snout and base of caudal; origin of the soft dorsal and the anal equi- 

 distant from the snout, one and one-half in l)ody length; the spinous dor-
