FISHES OF HAWAIIAN ISLANDS.

very broad on nuchal region; tip of tail narrowly white. In some of the cotypes, the dark cross-bands 
tend to break up below and form reticulations. 
This species is not rare about Honolulu among the coral rocks. It apparently does not reach a 
large size, the examples in hand ranging from 15 inches down to 6 inches in length. 
Echidna vincta Jenkins (type, No. 50687, U. S. Nat. Mus., a specimen 13.5 inches long, obtained at 
Honolulu. Cotypes, No. 7492, L. S. Jr. Univ. Mus., 15 inches long; No. 2753, U. S. F. C.; No. 2753, 
Field Museum), appears to be identical with this species. Specimens were also obtained by the 
Albatross at Honolulu in 1902.

Echidna polyzona, Fowler, op. cit. 496 (Honolulu); not of Richardson.

69. Echidna zonophaea Jordan & Evermann. Plate 21. 
Head 3 in trunk, or 6.5 in total; tail longer than head and trunk by a little more than the snout; 
eye 2 in snout, 1.5 in interorbital space; snout 6; interorbital space 7.75; mouth 2.8. 
Body compressed, the tail tapering rather narrowly posteriorly; head deep and compressed, 
pointed in front; snout rather long and pointed, the tip obtusely rounded and projecting considerably 
beyond the mandible; eye rather small, midway between tip of mandible and corner of mouth; 
mandible arched below so that only the anterior teeth touch the front of the jaw above, though the 
thick fleshy lips conceal them all; teeth molar, those in front of jaws pointed; anterior nostrils in 
short tubes, the posterior pair above the eye with a slightly elevated margin; interorbital space 
convex; top of head more or less swollen or convex in profile; gill-opening 1.67 in eye; skin smooth; 
head with a few pores; origin of dorsal beginning at last fourth of space between corner of mouth and 
gill-opening; caudal small. 
Color in alcohol, grayish white, the body and tail crossed by about 25 broad rich-brown bands, 
extending upon the dorsal and anal fins; dark bands anteriorly broadest above and not meeting 
across belly, their width about equal to the distance from tip of snout to middle of eye; first brown 
band through eye, second across nape, the fourth across gill-opening; gray bands of ground color 
anteriorly broad and widening much upon belly; posteriorly the gray bands are narrower and better 
defined, especially on the fins, their width scarcely greater than half that of the brown bands; tip of 
tail very narrowly white; body anteriorly, especially within the gray bands, profusely covered with 
numerous small, roundish, black specks, less numerous and more scattered posteriorly; no black 
spots on head; angle of mouth black, with a small white blotch immediately in front on lower jaw, 
continued across under jaw as a broad whitish band; side of head with about 4 or 5 narrow blackish 
lines between mouth and gill-opening; region of gill-opening marbled with dark brown and whitish, 
the opening dark. One example (No. 03545) had much yellow on the head and between the brown 
zones. This species is known from the type and 3 cotypes, all obtained by us at Honolulu. 
Echidna zonoplixa Jordan & Evermann, Bull. U. S. Fish Comm., XXII, 1902 (April 11, 1903), 167, Honolulu (Type, No. 
50621, U. S. Nat. Mus). 
70. Echidna leihala Jenkins. Fig. 32. 
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 
other, closing only at tip; a few sharp fixed teeth in anterior portions of jaws, the remaining all blunt; 
teeth in anterior portion of upper jaw sharp, in a single series; in the posterior portion a double series 
of blunt teeth, between which the roof of the mouth is crowded with blunt teeth, becoming as many 
as 6 series posteriorly; teeth in lower jaw in 2 series anteriorly, becoming blunt posteriorly and 
apparently in 3 series; anterior nostril tubular, near tip of snout above margin of lip; posterior 
nostril smooth, near the middle of the upper margin of the eye. 
Color in life, uniform yellowish brown, not lighter on the belly, being distributed over the whole 
body in fine granular markings; no transverse bands appearing in life, but evidence of bands,
