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

 snont, jaws, and preorbital naked ; lateral line running very high, as in 

 Jioh-ichthys fusiformis, from which this species is chiefly distinguished by 

 the scaly crown, a character seen also in P. tuncumlria. 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; ventrals, 

 anal, and pectorals plain. Length If 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 southsrnmost known species of the darters. Specimens 

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

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

Boleichthys, GIRARD, Proc. Ac. Nat. Sci. Phila., 1859, 103, (exilis). 



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

 section Oligocephalus under Etheostoma. The lateral line is incomplete and 

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

 the species of Etheostoma. Top of head not scaly. Lowland streams and 

 swamps; the species few, variable, and hard to determine. (3oM$, dart;
