Avliicli I briettj' described the specimen and compared it with Perciua 

 caprodes and Iladropterus aspi'o. Last summer the sandbars on the 

 sontli side of the east end of the lalce were again extensively seined and 

 among some 500 or 600 Percina caprodes two small specimens— probably 

 that summer's brood— Avere taken which, beyond 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 tj'pe 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.

 (New Species. ) 



Head 4; depth G.IO; D. XVI, 14; A. II, 11; scales 8- 70-9. 



The form of the body is much like that of II. aspro, rather elongate, 

 fusiform, somewhat compressed posteriorly, but less pointed anteriorly. 

 ;\Iouth moderately large, maxillary reaching to the pupil; the cleft of 

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

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

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



All scales ctenoid; nape with 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 equal 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 tlie soft dorsal and the anal equi- 

 ilistant from the snout, one and one-half in Ixidy length; the spinous dor-
