Jordan and Evermatin. — Fishes of North America. 1101 



opercles, and whole top of head closely scaled; breast and nape scaled; 

 snout, jaws, and prcorbital naked ; lateral lino running very high, as in 

 liolcichthys fusiformi.s, from which this species is chiefly distinguished by 

 the scaly crown, a character seen also in /'. tuscumhia. Gill membranes 

 separate, a small black humeral spot. Caudal long, 1;^ in head, rounded 

 or pointed behind; pectoral nearly as long as head. Color dark brown, 

 the pale parts chiefly bright red in life ; back with some dark markings ; 

 side with a broad black lateral band, mottled and interspersed with red; 

 an area of red along lateral line ; some black spots on lower part of side ; 

 a black spot at base of pectoral ; 3 black bars about eye; 4 or 5 round 

 black spots in a cross series at base of caudal, the 2 middle ones conspic- 

 uous; fins checkered; dorsal, anal, and caudal finely barred; veutrals, 

 anal, and pectorals plain. Length 1| inches. Swamps and streams of the 

 lowlands from Virginia to Florida ; known from Blackwater River, Zuni, 

 Virginia; Allapaha River, Nashville, Georgia, and various streams in 

 Florida; the southsmmost known species of the darters. Specimens 

 from Orlando, Flori.ia (Coll. Einar Lonnberg), are larger and more brightly 

 colored than those from the Dismal Swamp region, {quiescens, lying quiet.)

Boleiddhyn, Girard, Proc. Ac. Nat. Sei. Phila., 1859, 103, {exilix). 



This genus contains small and slender species allied to those of the 

 section OUyocephul as under Etheostoma. The lateral line is incomplete and 

 has a slight upward curve anteriorly instead of being straight as in all 

 the species of Etlu-ostoma. Top of head not scaly. Lowland streams and 

 swamps ; the species few, variable, and hard to determine. {3o7iig, dart ;
