14 CONTRIBUTIONS TO NORTH AMERICAN ICH1*HYOLOGY III. 



opposite the eye. Eyes large, high up, longer than the muzzle, 3J 

 in head : interorbital space rather narrow, the eye having some upward 

 range. Mouth moderate, slightly oblique, the maxillary reaching to 

 orbit. Upper jaw slightly longer than the lower, not protractile. Head 

 entirely naked, both cheeks and opercles being destitute of scales. 



Scales large, 5-4b'-5. Belly scaled: throat naked: neck anteriorly 

 naked, but scaly in front of the dorsal : lateral line complete. 



Fins all large : D, X-1, 10, or 1X-1, 11, the membrane of the first dor- 

 sal continued to the base of the second : longest dorsal spine a little 

 over half the length of the head, scarcely shorter than the soft rays; 

 the base of the spiuous dorsal a little longer than that of the soft dor- 

 sal. Anal II, 8, rather smaller than second dorsal, the first spine longer 

 and larger than the second. Caudal fin deeply lunate, almost forked. 

 Pectoral and ventral fins large; the former reaching nearly to the vent, 

 the latter somewhat shorter. 



Color, in spirits: Olive, closely mottled and tessellated above with 

 dark green ; this color extending down the sides, forming six or eight 

 irregular dark green bars. Head daik green ; a dark green line down- 

 ward from eye and another forward. Fins in males nearly plain, the 

 spinous dorsal with a black edge; females with all the fins except the 

 ventrals closely barred or speckled with dark green. Two pale orange 

 spots at the base of the caudal. 



Life-colors : The colors of a male specimen in life are as follows : Body 

 dark olive and blotched above: sides with nine dark blue-green vertical 

 bars, the five next the last most distinct, and reaching down nearly to 

 the anal. Spinous dorsal reddish at base, then with a broad black 

 band, the uppermost third being of a bright ferruginous orange-red : 

 second dorsal blackish at base, reddish above : caudal with two orange 

 blotches at base, black mesially, pale orange externally. Anal fin of a 

 brilliant blue-green color at base, pale at tip. Pectorals barred, the 

 middle of the fin grass-green. Ventrals dusky mesially, with a green 

 shade. Opercular region more or less grass-green : streaks about eye 

 blackish-green. 



Length of largest specimens taken, 2J inches. 



Habitat. Very abundant in all the streams seined, especially so in 

 the rocky shoals of Beedy Kiveriu the city of Greenville. 



This handsome little fish may be easily known from its congeners by 

 the smooth head, and by the general greenness of its coloration, which 

 resembles somewhat that of the species of Diplesium.
