 fourth length of body, in females somewhat lo^yer: its insertion almost 

 directly over first ray of ventrals. In the other similarly colored species 

 of Xoiro2)is the dorsal is evidently behind the ventrals. Coloration bril- 

 liant, clear dark blue above, sides and below abruptly silvery; a blue 

 lateral streak, much as in X. cwruleus, bounding the blue of the upper 

 parts, the white pigment of the lower parts looking as if painted over the 

 blue. Dorsal with a large black spot on its last rays above. Dorsal, 

 anal, and caudal with the usual satin-white pigment at their tips; these 

 fins otherwise of a clear, ferruginous orange. Females slender and dull- 

 colored. Length 21 inches. Ocmulgee River, Georgia. An elegant fish.
