BULLETIN OF THE UNITED STATES FISH COMMISSION. 
rather large, gape, reaching beyond eye a distance equal to length of snout; lower jaw scarcely the 
shorter, not much curved; teeth all pointed, in 2 series anteriorly and 3 series posteriorly in upper 
jaw, lower jaw with teeth in 2 series anteriorly, laterally and posteriorly in a single series; 2 large 
sharp-pointed depressible teeth on anterior part of vomer, followed by a series of about 6 smaller 
teeth on the shaft; anterior nostril in a short tube whose length is one-fourth diameter of eye, 
situated near tip of snout just above lip; posterior nostril without tube, situated above margin of eye 
just in front of vertical through middle of eye; gill-slit moderate, its length 1.5 in eye; origin of dorsal 
slightly in front of gill-opening, height of fin 3.5 in head; anal similar, but lower. 
Color in alcohol, body and fins light brown on a whitish background, the brown arranged in a 
somewhat regular network, giving the appearance of rows of indistinct whitish spots surrounded by 
polygonal brownish interspaces, which are most distinct on tail; no white border to the fins or tip of 
tail, ami no dark area around gill-opening. 
The only specimen known is the type, No. 50843, U. S. Nat. Mus. (original number 2354), a 
specimen 8.5 inches long, obtained by the Albatross at Honolulu in 1891. 
Gymnothorax ercocles Jenkins, Bull. U. S. Fish Comm., XXII, 1902 (Sept. 23, 1903), 428, tig. 8, Honolulu. 
Head 2.3 in trunk; head and trunk less than length of tail by a space a trifle greater than length of 
latter; eye about 2 in snout, 1 in interorbital space; snout 5.5 in head; mouth 2.3. 
(Body deep, compressed; tail tapering gradually posteriorly where it is greatly compressed; head 
compressed, sides above slightly swollen; snout elongate though rather short, blunt, rounded, not 
projecting beyond mandible; jaws even; eye small, covered with the skin of head, a little nearer corner 
of mouth than tip of snout; mouth horizontal, the rather thin lips more or less concealing teeth; teeth 
rather large, sharp, in several series, or in a broad patch on each side of upper jaw, uniserial in 
mandible; large canines in front of both jaws, Vomer with a single median series of small ones; anterior 
no’strils in short fleshy tubes near tip of snout; interorbital space narrow and convexly elevated; gill- 
openings small, a little below middle of its depth and about equal to eye; pores of body small; origin 
of dorsal a little before corner of mouth, fin rather high, and together with anal, which is more or less 
similar, confluent with small caudal. 
Color in life, dark brown; head, body, fins, and tail covered with numerous distinct white spots, 
larger than eye on the trunk, smaller elsewhere; tip of tail white; margin or gill-opening brownish- 
black. The two specimens examined, taken by Dr. Jenkins at Honolulu, are each about 6.5 inches 
long, and do not differ in coloration. 
The species is distinguished from G. meleagris by the more anterior insertion of the dorsal, and 
the larger and fewer white spots, which are larger on the trunk than elsewhere.
