total length. Posterior extremity ot" maxillary extending to the vertical 

 line of the anterior rim of pupil ; eye circular ; its diameter contained 

 about four times in the length of side of head; external soil ray ofven- 

 trals continued into a membranous thread extending beyond the other 

 rays, but not reaching the anal fin. Caudal emarginaled posteriorly. 



D. X. 14; A. III. 8; C. 4, I. 8, 7, I. 3 ; V. I. 5 ; P. 15. 



Scales well developed ; in six rows above lateral line, and fourteen 

 to fifteen below. 



General color light olive green, with narrow, well defined longi- 

 tudinal lines of purplish brown along the sides ; one through the centre 

 of each row of scales. These lines, above the lateral line, are parallel 

 to it ; below, they are somewhat oblique, ascending behind. A nar- 

 row, well defined horizontal line of steel blue passes beneath the eye, 

 tangent to the orbit ; a broader one of violet extends through the pupil, 

 parallel to the upper outline of the head. 



D. light olive green, the distal half of the spinous portion dull pur- 

 plish; the membrane elsewhere mottled with purplish brown. C.with 

 rays 3'ellow and red, the membrane mottled with purplish. 



A. and V. yjurplish red anteriorly, yellow behind, the former some- 

 what mottled. P. greenish voUow. A narrow margin of D. A. and

About six vertical broad bars of dark purpfish brown on each side 

 between head and tail; the first just anterior to the dorsal fin. The in- 

 termediate space, wlien viewed directly, appears of a brownish olive 

 and greenish white mixed; but, held a little obliquely, this resolves into 

 ;i silvery tint, with well defined longitudinallines of purplish, a line for 

 t:ach row of scales, and usually along the adjacent edges. Above the 

 lateral line these lines are oblique, and nearly parallel with the dorsal 

 profile anterior to the D. fin. Head above (excepting a lighter bar be- 

 neath the eyes), operculum, and an obhque bar beneath the eye rich 

 purplish brown. Back along the dorsal fin and a space on each side 

 of the nape witli reflections of rich metallic green. A dark spot on the 

 base of th(> pectoral bones. Belly white, closely punctate wdth dark 

 brown. 



D. with the rays silvery, the membrane mixed green and purplish 

 brown, the margin clear dark reddish brown. C. brown at base, then 

 greenish, then violaceous white, and ending in dark purplish brown ; 

 these colors in rather ill defined V-shaped bands, parallel with the
