Chromis velox Jenkins, new species. Fig. 6. 
Head 3.5 in length of body; depth 2.33 in length. D. xiv, 11; A. ii, 11 or 12. Profile of head and 
body regularly and symmetrically rounded above and below, except the head before eyes where it is 
slightly concave; in some the nape appears somewhat bulging, due to the depression below. Length of 
caudal peduncle a little less than 2 in head, depth at middle equal to its length. Eye elliptical, 3 in 
head, equal to interorbital space. Interorbital convex. Snout 4 in head. Preorbital at narrowest 
part 3 in eye, its edge entire. Edge of suborbital concealed by scales. Preopercle entire, its angle 
rounded. Opercular margin entire, without spines. Teeth conical, in a single series in each jaw. 
First dorsal ray equal to eye, two-thirds of third; third and fourth longest, 2 in head; following spines 
successively shorter, last slightly shorter than second. Soft dorsal rounded; first rays abruptly longer 
than last spine, equal to third and fourth spines, last ray equal to fourth spine. First anal ray very 
short, the second equal to tenth spine. Soft anal longer than soft dorsal, rounded, median rays equal 
soft dorsal rays. Caudal deeply forked, upper lobe the longer, longest rays 3 in length of body. 
Pectoral large, pointed, upper rays longest, 3 in length of body. Yentrals a little shorter than head, 
slightly greater than 4 in length of body. All parts of head and body, except lips and a minute ridge 
from nostril to eye, scaled, and scales on opercle enlarged. Scales on body 4-29-9. Lateral line arched, 
beginning above upper end of gill cleft, extending over first 20 rows of scales. 
Color in alcohol: Brownish or dusky olive above, below silvery yellowish; base of pectoral black, 
color not extending to axil on body; about eight indistinct longitudinal dusky streaks along sides of 
body, below dorsal dark region, following rows of scales;' membrane of spinous dorsal black; soft anal 
and dorsal dusky; caudal dusky brown.
