Fishes of Upper Georgia. 339 



caudal, as usual, filled with satin-white pigment. No red. Young with 

 the black, white, blue, and yellow obscure. 



D., I, 8. A., I, 8. Length 3 inches. Teeth 1,4-4,1, of the usual type, 

 hooked and sharp-edged. 



Habitat. This exquisite little fish occurs in abundance in 

 the clear tributaries of the Oostanaula River, above Rome, 

 Ga. Most of our specimens were taken in Rocky Creek, — 

 one of the clearest of the mountain streams of that region. 

 It also goes in shoals in the river channel. 



I give below an attempt at a synopsis of the species of 

 this genus described from the region east of the Mississippi. 

 Of these, eurystomus was found in the Chattahoochee River, 

 and xcenurus in the Ocmulgee. These will be described 

 further on. Grandipinnis Jordan MSS., will be elsewhere 

 characterized. Spilopterus Cope, is from the Ohio Valley 

 and north-west ; pyrrhomelas, from North Carolina. Uer- 

 costigma Cope, calliura Jordan MSS., and analostana Grd., 

 are true Cyprinellw, having serrate teeth. 



Galacturus Cope, has the physiognomy of Photogenis, but 

 differs in having the grinding surface on the teeth. It is 

 probably referable to Luxilus. 



* Anal fin elongate, I, 10 or I, 11 ; no distinct caudal spot; 

 body and head stout; fins red in #. 

 f Scales on flanks tuberculate as well as those on head 



and neck, Ocmulgee River, .... X/ENURTJS.
