338 Fishes of Upper Georgia. 



Scales large, deep, less closely imbricated than in coeruleus or analostanus ; 

 39 in the lateral line (38 to 41), 15 or 16 in front of dorsal. Fins rather 

 large, the height of dorsal about 5£ in length of body. Dorsal fin slightly 

 behind ventrals, midway between snout and caudal. Ventrals reachiug 

 vent; pectorals not to ventrals. D., I, 8. A., I, 8 (sometimes I, 9). 



Coloration dark and brilliant. Back very dark steel blue; sides a very 

 clear silvery violet, with blue shades ; belly and lower fins satin white. 

 A heavy black spot on upper posterior part of dorsal, extending down- 

 ward and forming a horizontal bar at the base which rises into a sort of 

 spot in front, as in Lythrurus diplcemius ; the rest of the flu bright vermilion 

 red, excepting the silvery tip. Caudal satin white at tip ; the rest of the 

 flu bright red, except the yellowish base. 



A red lateral streak in place of the usual golden one : a broad golden 

 vertebral band. 



A large distinct round black spot at base of caudal, not so bright as in 

 stigmaturus, the pigment seeming to lie under the scales (i. e., scales less 

 transparent than in stigmaturus). 



Females paler in color, with less black and no red. 



Teeth 1,4-4,1, as in stigmaturus. Length 4 inches. 



Habitat. Tributaries of the Etowah and Oostanaula, in 

 clear water. Most of my specimens were taken in Silver 

 Creek. 



27. PHOTOGENIS OERULEUS. Sp. nov. 



Body fusiform, somewhat elongated, moderately compressed; depth i} 

 in length (4^ to 5). Head moderately large, 4^ in length (4A to 4^), the 

 snout rather pointed, overlapping the small, oblique mouth. Upper sur- 

 face of head and neck thickly covered with small tubercles, in the males. 

 Eye moderate, 3^ in head ; the iris white. jVIaxillaries reaching nostrils. 



Scales firm, high and narrow, edged with dusky, 38 in the course of 

 the decurved lateral line (37 to 39) ; 13 to 17 in front of dorsal. 



Fins all high, the height of the dorsal nearly ± of the length of the fish. 

 Dorsal fin behind ventrals, its beginning equidistant between base of cau- 

 dal and front of eye. Pectorals not reaching ventrals ; the latter to vent. 



This is one of our most elegant species. Its general color is a bright 

 steel blue; the sides more silvery, pinkish-shaded anteriorly; the belly 

 silvery white. Along the sides is a very distinct brilliant blue-green baud, 

 most conspicuous towards the caudal fin. This color is not a matter of 

 lustre, but depends on the presence of blue pigment lying under the 

 scales. In spirits it becomes of a dark steel blue color. 



Fins all clear bright yellow, as in a highly colored Chrosomus. A vague 

 diffuse dusky blotch on last rays of dorsal, as usual, and some black edg- 

 ings on the anterior rays of most of the fins. Tips of dorsal, anal, and
