BULLETIN OF THE UNITED STATES FISH COMMISSION. 
11 inches; gill-opening narrow, longitudinal, length less than diameter of cornea; interorbital space 
equal to diameter of cornea; distance from posterior margin of cornea to angle of mouth about equal 
to distance from anterior margin to tip of snout; dorsal tin beginning at occiput, in height about 0.5 
depth of body; height of anal about diameter of cornea; teeth all pointed, long, and in a single series 
in each jaw; 3 long sharp teeth on vomer. 
Color in life, light brown, with 17 distinct wide, dark brown bands encircling body and fins, not 
much narrower across the dorsal, much narrower or interrupted on ventral aspect on forward part, less so 
on posterior part of tail; bands nearly equal to depth, on anterior portion quite equal to depth; a white 
spot on outer margin of dorsal on each side each dark brown band; between white spots a dark brown 
spot; spaces between dark bands on anal nearly white; area between eyes, angles of mouth, and borders 
of lower jaw, dark brown; from dark brown area between eyes to first dark brown band, yellow. 
This species differs from G. petelli in the white spots on margin of dorsal and white areas on anal, 
in distinctness of bands, and their encircling the dorsal and anal. 
Only one specimen known, type, No. 50682, U. S. N. M. (original No. 280), 21 inches long, obtained 
by me from the coral rocks at Honolulu. 
19. Gymnothorax ercodes Jenkins, new species. 
Head 6.6 in total length, or 3 in distance from tip of snout to vent; depth 12; snout 6.6 in head; 
eye 1.3 in snout; gape 2.6; tip of snout to vent 1.35 in tail; interorbital width slightly greater than 
eye, or nearly equal to snout. Body moderately elongate and much compressed; tail more compressed 
and pointed; mouth rather large, the 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 the teeth in 2 series anteriorly, laterally and posteriorly in a 
single series; 2 large, sharp-pointed, depressible teeth on anterior part of vomer, followed 1 >y 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 the 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 net-work, 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, and no dark area around gill-opening. 
The only specimen known is the type, No. 50843, IT. S. N. M. (original No. 2354), 8.5 inches long, 
obtained by the Albatross at Honolulu in 1891. 
20. Echidna leihala Jenkins, new species. 
Head 7 in total length; depth 2.1 in head; tip of snout to angle of mouth 2.5 in head; eye 10 in 
head; interorbital 8.5; gill-opening a very small narrow slit, 3 in eye, with no distinguishing color- 
marking; origin of dorsal well in advance of gill-opening, 3 in head; jaws curving away from each
