Body comparatively stout, short and thick, compressed behind the head, 

 caudal pedicel deep and short, head and nape broad, depressed on the 

 upper surface. Head longer than depth of body, nearly one third of the 

 length to the base of the caudal, as broad as deep, crown flat. Snout short, 

 not as long as the eye, blunt, rounded ; chin steep. Mouth large, directed 

 obliquely upward, lower jaws longer, firmly united ; upper short, protractile. 

 Teeth conical, hooked ; outer series larger, in open order ; inner small, in 

 bands ; pharyngeal with a shoulder. Eye large, little longer than the snout, 

 nearly two fifths of the head, half of the forehead. Dorsal origin almost 

 directly opposite that of anal, two thirds of the distance from the eye to the 

 base of the caudal, or half of that from the occiput to the end of the caudal 

 fin. Anal larger, deeper and reaching farther back than dorsal. Ventrals 

 small, not reaching anal. Pectorals narrow, pointed, not reaching bases of 

 ventrals. Caudal deep, short, little more than half as long as the head, con- 

 vex on the hind margin. Scales large. Intestine short, hardly as long as 

 head and body. 



Olivaceous, light and yellowish to dark and brownish, whitish to silvery 

 beneath and on the lower half of the head, edges of scales darker. A small 

 spot of brown on the base of each scale, of the upper flank and back, gives 

 the appearance of vittae. Fins plain, or with transverse streaks, or clouded, 

 or darker toward the tips. A darkish streak behind the eye. A faint dark- 

 ish streak along the middle of the side. Top of head dark. Small to 

 medium sized specimens have a blackish patch behind the upper angle of 

 the operculum, half a dozen or more narrow, more or less distinct, vertical 

 streaks of brown on the hinder portion of the body, and transverse series of 

 dots on dorsal anal and caudal, more or less zigzag on the last. Small and 

 light colored individuals have a narrow band of brownish from the eye 

 around the lower lip. Largest specimen two and one half inches.
