moderate size ; longest dorsal spine 2| in head ; longest soft ray 1 ; 

 caudal subtruncate, its longest ray 1 in head ; longest ray of anal \\ ; 

 pectoral a little longer than head ; ventral a little shorter. Color of 

 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 

 some dark specks and some dashes of orange ; breast with light-orange 

 shades ; first dorsal with a broad median band of blue black ; a paler 

 stripe below it and above it ; the base of the fin with dark interspinal 

 spots, and the edge of the fin again blackish; second dorsal blue black, 

 dashed with orange toward the base ; caudal blackish, rather darker at 

 base; anal blue black, with orange yellow at the base; pectoral blackish, 

 with orange cross shades; ventrals blue black, with some edgings of 

 orange. Young examples similarly marked, but paler in color, with 

 more distinct markings, especially the dark cross bars on back, which 

 are often very distinct, much as in Cottogaster uranidea ; fins in females 

 and young paler. Length 3i inches. Ohio River 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 (cceruleum andpeltatus).

Head4i; depth 6; eye 4 in head. D. XI or XII-12 to 14; A. II, 9; 

 scales 6-48 to 57-7 or 8. Form of Ulocentra simotera. Body robust, some-

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

 River), seems to belong to Etheostoma variatum. Anal large; dorsal spines 12; scales 49. Gill 

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

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

 and this locality may be doubtful. 



fThis group is very closely allied to Ulocentra.
