The above description is based upon the type, 10.5 inches long, the only example known, obtained 
by Dr. Jenkins at Honolulu in 1889. 
Scriola sparna Jenkins, Bull. U. S. Fish Comm., XXII, 1902 (Sept. 23, 1903), 442, fig. 14, Honolulu; type, No. 50845, U. S. N. M. 
(field No. 742), coll. 0. P. Jenkins. 
Genus 109. ELAGATIS Bennett. The Runners. 
Body long and slender; second dorsal and anal long, each with one detached finlet, composed of 
2 rays, behind the rest of the fin; otherwise essentially as in Seriola. One species, pelagic.

Head 4.3 in length; depth 5.5; eye7.3in head; snout 2.6; I>. vi-i, 25 + 2; A. r, 18 + 2; interorbital 
2.9; maxillary 3.1; mandible 2.5; scales about 100. 
Body oblong, pointed, the back little elevated; head moderately long and pointed; snout long, 
conic, the jaws subequal; maxillary broad, triangular, its greatest width 2 in its length; supplemental 
maxillary long and narrow; slipping under the thin preorbital; teeth in broad villiform patches on 
jaws, vomer, and palatines, tongue naked; eye small, somewhat anterior; interorbital space broad, con- 
vex ; preopercle and operele entire; gillrakers about all below the angle, cephalic ones gradually shorter, 
longest about 1.5 in eye; fins moderate; origin of spinous dorsal over tips of pectorals, the rays weak 
and short, folded somewhat in a groove, the longest 2 in snout, the fin not connected to soft dorsal; 
soft dorsal long and low, anterior rays elevated, longest 2.9 in head, last ray equal to eye; last ray of 
dorsal finlet produced, its length 3.6 in head; distance between dorsal finlet and base of last dorsal 
ray 1 in eve; distance from last ray of dorsal finlet to base of caudal lobe 3.6 in head; origin of anal 
under about the fifteenth dorsal ray, the fin very low, anterior rays slightly elevated, the longest 4 in 
head; detached anal spines obsolete; caudal very deeply forked, lobes long and slender, their length 
equaling distance from snout to first third of pectoral; pectoral short, scarcely falcate, 2 in head; ven- 
trals about equal to pectoral; scales small, numerous, cycloid; head naked, except cheek and postocular 
region; scales on cheek in about 7 series; scales on nape and antedorsal region smaller than elsewhere; 
lateral line well developed, continuous, forming a very low keel on last part of caudal peduncle. 
Color in alcohol, dark blue or leaden above, becoming paler and yellowish below; under parts 
dirty white; fins dusky, yellowish, or olivaceous. In life 2 conspicuous blue bands on side of body, 
the upper beginning at orbit and passing to dorsal margin of caudal peduncle, its width about equal to 
that of eye, the other beginning at snout and passing along the lower margin of orbit across operele 
and above pectoral fin to the caudal; caudal yellowish with a darker margin; ventrals and pectoral 
yellowish with some blue.
