ON SOME ETHEOSTOMINE PERCH FROM TENNESSEE AND 



NORTH CAROLINA. 



By E. D. Cope. 



Etheostoma, Raf. 



The species of this genus are nearly allied to each other. I gave a 



synopsis of the three with which I was acquainted in 1866 (Trans. Ainer. 



Philos. Soc, p. 400), and now add characters of two other species. They 



are to be compared with the E. peltatum, Stauffer, and E. maculatum, 



Girard. 



A Scales 7-8—52-5—8-12. 

 I. Head 4.5 to base of tail ; cJieeks scaled. 

 R. D. XIII 1.12 A II. 8 Muzzle obtuse, wide ; maxillary, to line of 

 j)upil ; maxillary teeth nearly equal : a series of separate spots on the 

 sides behind scapula. e. nevisense. 



II. Head 3.6 to 4 times to origin caudal ; cheeks naked. 

 R. D. XI-KII. 12-13 A II. 9 Muzzle compressed acute; maxillary to 

 line of pupil ; a larger series of maxillary teeth exteriorly ; a series of 

 eight sj)Ots on the sides connected by a baud; eye near four times in head. 



E.? MACULATUM, var. 



"R. D. XIV.14 A 11.10 Maxillary to line of orbit." Girard. 



E. MACULATUM. 



R. D. XIII. 13 A.I. 10 Maxillary to line of pupil. E. peltatum. 



Etheostoma nevxsekse, Cope. 



Sp. nov. 



This is an elongate fish, with muzzle obtuse in profile, as well as wide, 

 viewed from above ; cheek, operculum and median dorsal line scaled ; 

 ventral line without spinous scales, one only present in the symi^hysis of 

 the "coracoids." Isthmus very narrow. Anal fin with base a little 

 shorter than second dorsal ; the species may really be a Poecilichthys. 

 Scales 8 — 53—11. First dorsal moderately elevated ; second peculiar in 

 spinous ray, well separated from the first dorsal. Caudal fin slightly 

 forked. 



Ground color above yellowish, crossed by nine dark chestnut quadrate 

 spots on the median line, which are wider than their interspaces, and are 

 connected at their ends by an undulate chestnut band. Below the latter 

 a similar longitudinal band on the anterior half of the body. Six quad- 

 rate black spots on the sides, with a small spot between each. A dark 

 band from end of muzzle to scapula ; below it on operculum, a silver spot. 

 A black bar below eye. Belly white. Caudal and second dorsal dis- 

 tinctly, pectoral and ventral, faintly black barred. A series of black spots 

 along middle of first dorsal. 



Length 3 in. 25 lin. Diameter orbit 2.2 lines. Depth at first ray second 

 dorsal 4.8 lines ; at occipital region 4 lines. 



This species, though near the next in general appearance, is very dift'er- 

 ent in details of structure, and I am not sure that it may not be referable 

 to the genus Poecilichthys. It is based on one specimen which was taken
