REVIEtV^ OF RAFINESQUE ON AMERICAN FISHES. 19 



common species in Southern Ohio and Indiana. Pomotis macroclnra 

 Kirtland is based, in part at least, on Lepomis imlUdus (Mitch.). Ichthelis 

 macroclnra Jordan (Man. Vert.) is a Xenotis, to which I have since 

 given the name of X. aureolus. 



* 7th species, Blue Sunfish, ICTHELIS CYANELLA, Icthele bleuatre. 



Apomotis cyanellus Eaf. 



Bryttus punctatus Cuv. & Val. / 



CalUurus lottgulus Girard. 



C alliums for mosus Girard. 



CalUurus longulus Bliss {in lit. — specimens identified). 



Chcenohryttiis mineopas Cope. 



Ictlielismelanops Eaf. [Chcenohryttus melanops Cope, not of Gill.) 



Eafinesque's description, although erroneous in one or two particu- 

 lars, refers to a species of Apomotis, and the name cyanella has priority 

 over all others. As in nearly every case the "diameter" is made too 

 small ; evidently Eafinesque trusted his eyes in such cases instead of a 

 tape-line. 



tSth species, Black-Eye Sunfish, ICTHELIS MELANOPS, Icthele seuil- 

 noir. 



Apomotis cyanellus Eaf. 

 Description somewhat erroneous, but characteristic.

 Hue dotts ; brownish above; head elongate, lower jaw longer, cheeks ivith Hue flexuose lines ; 

 spot oblong, blackish, nearly marginal; tail rounded, notched; anal fin very broad with 

 12 rays, whereof three are short spiny ; pectoral fins very short. 



A small species hardly three inches, called Blue-fish or Sun-fish. I found it on the 

 Ohio at the falls. Appearing entirely blue at a distance. Head brown above ; iris gilt ; 

 opercle curved; tail olive-blue with 24 rays. Dorsal fin brownish with 20 rays, 

 whereof 10 are spiny, hardly any middle depression. Pectorals small trapezoidal, 12 

 rays. Thoracic one and five. 



t Body oblong, diameter one-fourth, olivaceous, covered with blue dotts, neck brown above, 

 head large, mouth rather large, upper jawlonger ; opercule with blue curved and longitudi- 

 nal Vines beneath. ; s]}ot rounded, black at its base; fins olivaceous, tail bilobed; anal 

 fin with three and nine rays ; pectoral fins large oboval. 



Length from 2 to 6 inches ; common in the tributary streams of the Ohio, the Ken- 

 tucky, Licking, Miami, &c., and even in small creeks. Vulgar names, Blue-fish, Black- 

 eyes, Sun-fish, Blue-bass, &c. It has black eyes (pupils) like all the other species, but 

 the iris is black also, with a silvery hue or ring. Dorsal fin with 10 and 10 rays, the 

 spiny ones very short. Caudal 20. Pectoral 16. Thoracic 1 and 5 as usual, but the 

 spiny ray is very short, as are also those of the anal fin.
