334 Fishes of Upper Georgia. 



Its coloration is brilliant, and reminds one of Ghrosomus 

 erythrogasler, and it is possibly the species referred to by 

 Prof. Agassiz (above cited) as having a continuous lateral 

 line. This species is apparently related to Ht/bopsis rubri- 

 croceus, chiliticus, and clilorocephalus Cope, but I cannot 

 identify it with any of them, nor with any of the species of 

 Alburnops Girard, to which group or subgenus the present 

 species belongs. 



My specimens show the following characters. 



Form chubby, little compressed, much as in Chrosoraus, the back some- 

 what elevated; depth 4I£ to 5£ in length; caudal peduncle not much con- 

 tracted, but more so than in xcenocephalus. Head rather large, 41 to 4£ in 

 length, rather rounded above, with the snout somewhat pointed : mouth 

 large, oblique, upper jaw a trifle longest. Eye as long as snout, 3 to 3£ in 

 head. 



Scales everywhere large, slightly dark-edged, but not enough so to give 

 a dusky color. Lateral line scarcely decurved, continuous, with 36 to 38 

 scales; dorsal scales large, as usual in this genus, 16 before the dorsal fin. 



D., I, 8. A., I, 8. Dorsal fin very slightly behind ventrals; pectorals 

 not reaching ventrals; the latter reaching vent. 



Snout minutely tuberculate in males, as in Ilybopsis oioenocephalus and 

 Nototropis rubrifrons ; teeth in all examined 2, 4-4, 2. 



Coloration (in spirits) pale yellowish, with a plumbeous lateral baud 

 and a pinkish stripe above it ; snout dusky. 



In life, — back of a clear hyaline green as in Labidesthes, but with bril- 

 liant blue reflections; belly, etc., clear silvery, with blue lustre, not 

 yellow. A scarlet bar across dorsal, anal, and base of caudal ; a scarlet 

 band from upper edge of opercle to caudal, very bright when the fish is 

 just dead, shining silvery red in life. Iris with a red touch above. Sides 

 with a very distinct silvery band, below the red line. A row of black 

 dots along lateral line, forming a small distinct spot at base of caudal. 

 Top of head aud vertebral line golden; tubercles whitish. 



Habitat. In Etowah, Oostanaula, and Coosa Rivers, and 

 their tributaries, quite abundant in shallow still places and 

 fords in the creeks, where it is often the commonest of the 

 little Minnows. Length 2£ inches. 



24. HYBOPSIS X^NOCEPHALUS. Sp. nov. 



This small species is an ally of the last, but it is entirely
