 large male specimen, dusky greenish above, the head similar, the centers 

 of the scales darker, and the whole body covered with fine dark points 

 visible ■with a lens ; belly and sides of the body from anal fin forward 

 and as high up as the level of the scapula of a bright yellow orange; 

 posterior parts of the body with 5 vertical zones of bright orange, 

 these about half as broad as the dark greenish interspaces ; first zone 

 opposite the interspace between the dorsals and extending downward to 

 front of anal ; the last two on caudal peduncle ; a vague, dusky area on 

 base of caudal ; a dusky shade across nape in front of dorsal, with 2 or 

 3 blackish cross blotches on back behind it; head nearly plain, with

 and young paler. Length 3^ inches. Ohio Eiver basin from western 

 Pennsylvania,* through Ohio, Indiana, and Kentucky; generally rare, 

 probably more common southward. A large, handsome species, not 

 recognized for nearly thirty years after its discovery, the name variatus 

 having been meanwhile transferred to other species (cwruleum and jyeltatus).

* A specimen in the Museum of Comparative Zoiilogy from Easton, Pennsylvania (Delaware 

 River), seems to belong to Etheostoma rarintiiiu. Anal large; dorsal spines 12; scales 40. Gill 

 membranes united; belly scaled; premaxi Mary not protractile; a dark spot on last dorsal spine, 

 color otherwise faded. There is no other record of this species from east of the Alleghauies, 

 and this locality may be doubtful. 



t This group is very closely allied to Ulocentra.
