This handsome species, one of seven recorded by Agassiz from the Bend of the 

 Tennessee River, is not uncommon in the Holston River, Va. 



Lepomis gillii Cope, sp. nov. 



An elongated species, peculiar in appearance and characters, resembling the species 

 of Ambloplites. It is ^defined from a single specimen, which is probably not fully 

 grown. 



Fourth and fifth dorsal spines longest, exceeding any of the soft rays ; first ray 

 not small ; ninth and tenth nearly equal. Basis of dorsal equal from its first ray to 

 nares. Caudal fin moderately notched; anal spines elongate. Pectorals reaching 

 anal, ventrals not. Radii D. x. 10. A. iii. 9. V. i. 5. P. 13. This fish is gradually 

 acuminate in outline to the end of the muzzle. The head enters length 2-6 times, 

 and the depth, which is greatest at first dorsal ray, is equal. The eye's diameter is 

 longer than muzzle, and enters the head three times, and 1-5 times the interorbital 

 width. Scales 7 — 4.5—12, larger than those of operculum; those of pectoral region 

 smaller than latter. The mandible projects beyond premaxillary border. The 

 spines of the latter bone form a prominence in front of the orbit. The mucous 

 cavities are large, especially on the preoperculum ; those of the vertex nearly 

 margining the broad fronto-parietal groove. 



Total length 2 in. 7 lin. ; to base of first dorsal ray 9-75 lin. ; to do. of anal 15 lin. 



Light green, slightly silvery below ; several indistinct dark cross-bars above the 

 lateral line and across caudal peduncle; punctulated with black below; dorsal, 

 caudal and anal clouded with the same. 



This very distinct species was taken in a branch of Tuckahoe Creek, in the 

 bottoms of James River, twelve miles above Richmond. It is very distinct from 

 those previously described, and is named in honor of my friend, Prof. T. Gill, of the 

 Smithsonian Institution.

In this species the preoperculum possesses three spines, as in U. mer'ulionnlis 

 Girard. It differs from that species in its more slender form, the depth bein^- one-fifth 

 instead of one-fourth the length to caudal; in the more numerous 16—17 r;i\s of the 

 pectoral, and the double furcation of the caudal rays, which Girard denies tlie U.
