Depth 2. D, XVI, 8; A. X, 9. Caudal peduncle very short, its height 

 at root heing twice as great as it is long, and it comparatively rapidly 

 narrows to caudal; head having forehead slightly gibbous, and snout 

 rectilinear and pointed in front ; length of snout little more than that 

 of head ; interorbital area slightly raised ; preoperculum nearly vertical 

 and at angle boldly rounded; buccal scales in 5 rows; jaws normally 

 developed ; supramaxillary terminating at a vertical about a pupil's length 

 in advance of eye; lips moderately dsveloped, the lower interrupted in 

 front; teeth of outer row rather strong; dorsal fin moderately developed; 

 dorsal spines increase in a regular, bold curve from first to sixth, and the 

 following nearly equal ; longest rays, bent backward, extend for length of 

 basal half of caudal; anal fin very long and commences under ninth dor- 

 sal spine; spinous portion not much less than 3 times longer than soft; 

 first 3 spines rapidly graduated and following ones nearly equal; long- 

 est soft rays reaching backward to terminal half of caudal; caudal fin 

 forms i of extreme length, its angles round and the posterior margin 

 slightly emarginated; pectoral fin extending backward nearly to verti- 

 cal of fifth or sixth anal spine; ventral fins also reaching to nearly 

 same point ; parts above and below longitudinal axis nearly equally bal- 

 anced ; back declines moderately in a curve toward tail and in front of 

 dorsal slightly, but regularly decurved toward forehead. Color bronze 

 olive, with 7 indistinct cross bands; at base of tail a faint spot, chiefly 

 above lateral line ; fins dusky and immaculate. Lake Nicaragua. (Gill &

Body oblong, compressed, somewhat elevated, the form Centrarchoid. 

 Head rather large, scaly on the cheeks and opercles; preopercle entire. 

 Mouth rather small, terminal, low, moderately protractile, the jaws sub- 

 equal, lower lip without frenum, its fold being continuous; maxillary

 teeth, behind which, in front, is a narrow band of villiforin teeth. Gill
