224 ON THE DISTRIBUTION OF FRESH-WATER FISHES 



Greatest width mouth equal top of head and muzzle; two divergent 

 frontal ridges; eje 1'5 times frontal width ; black opercular spot 

 small ; dorsal and anal rajs very short, ..... melanops. 



Maxillary extending to beyond orbit; cheek scales large as those of 

 operculum ; dorsal and anal spines longer ; centres of the scales 

 dark-spotted, ........ . charybdis, 



Lepomis ophthalmicus Cope, sp. nov. 



In general this species resembles the L. gillli, that is in its elongate form and pale 

 coloration, but is characterized as much by its short dorsal spines as tlie latter is by 

 its long ones, as also by its much smaller mucous cavities, and many other features. 



The depth enters the length 2-66 times; the dorsal outline descends gradually 

 posteriorly, but is full and abrupt anteriorly. Eye unusually large, 3-3 in length of 

 head, longer than muzzle, and 14 times interorbital width. Head 2-85 in length. 

 Mandible not longer than premaxillary. Ear flap very short. Pectoral scales much 

 smaller than lateral ; those of cheek in seven straight, eight obliquely counted. 

 Scales 7—41—13. Radii x. 10. A. iii. 10. V. i. 5. P. 14. Neither pectorals nor 

 ventrals reaching anal fin. Caudal emargination not deep. 



Total length 3 in. 7-5 lines. Depth at first dorsal ray 13 lin.; at fifth ray second 

 dorsal 9'5 lines. 



General color light olive, with prominent black opercular patch which has no light 

 margin ; caudal fin dusky ; otherwise the specimen before nie has no markings. 



One specimen taken in the head of the Roanoke River.

 Proc. Acad. Nat. Sci. 1SG4, p. 84, Bryttus. 



Two specimens from tributaries of the Kanawha river, one from Giles, another 

 from Wythe county, Va. The coloration in life was as follows : 



Dark brown, with some blue bands acro.ss the head, and indistinct transverse dusky 

 bars on the sides. Second dorsal, caudal, and anal fins orange-margined. This fish 

 is widely distributed. The Academy Museum has it from the Miami River (Elijah 

 Coffin coll.) and from the tributaries of the Missouri near Leavenworth, Kansas 

 (Samuel Edge coll.) ; tlie original locality is Lake Whittlesey, Minn. 



This fish answers quite well to Girard's description of his Calliurus formosus 

 (from which C. longulus is not distinguishable as figured and described), but differs 

 much from his figure, in the much shorter spinous radii in dorsal and anal fins. 



Lepomis appendix Mitcli. 

 A nearly yellow variety of this fish from John's Creek, one of the head waters of 

 the James.
