Gosse’s figure of this species gives the shape of G. punctata with a more 
convex and regularly rounded caudal, in which the upper portion is a little 
the longer, and with the origin of the dorsal nearer the middle of the total 
length and a less distance backward of that of the anal. He gives the 
formula D. 11; A. 10; V.6; P13; Lil. 31; Ltr. 9. “The body almost 
pellucid ; olive above ; the sides pearly, with rich amethystine reflections ; 
green and golden hues prevail on the cheeks and gill covers; a black band, 
rising from the upper side of the base of the pectoral, runs along the side 
about one third of the length ; the dorsal and caudal are edged with black- 
ish. Length to two inches.’ Gunther gives a number of additional 
particulars. 
Depth three tenths of the length to the base of the caudal; head three 
elevenths. Snout broad, blunt. Chin steep; lower jaw longer. Eye as 
long as snout, three fifths of interorbital space, one third of head. Dorsal 
and anal moderate. Dorsal origin midway from front of orbit to tip of tail, 
above sixteenth scale of lateral line, opposite the middle of the base of the 
anal. Free portion of tail short, depth equal to distance from dorsal. Sides 
of abdomen silvery ; the portion above the silvery black.

In form this species is not greatly different from G. Holbrookii. The 
coloration, large scales, large eye, and pointed anal fin in the females, serve 
as ready means to distinguish it from any others of the genus. Body com- 
pressed, head depressed, depth of body or length of head about one fourth 
of the total length. Snout short, not as long as eye, broad, blunt. Chin 
moderately steep. Mouth medium; lower jaws longer, firmly united ; upper 
short, protractile. Teeth conical, hooked, in bands, outer series stronger and
