jaws and in front of eye, very minute'on all the fins except vontrals; lateral line concurrent with dorsal 
outline; peritoneum dark gray. 
Color in life, dark steel-blue, becoming paler below; a definite deep blue stripe from snout below 
eye widening on opercle, and thence straight to center of base of caudal; below it a narrow bright 
golden stripe from angle of mouth to lower part of caudal, and then a fainter blue stripe below this; 
a blue stripe from eye to upper part of gill-opening, interspace golden shaded with green; a deep blue 
stripe, not sharply defined, from upper part of eye along each side of back to base of upper caudal

Type, No. 50664, U. S. Nat. Mus. (field No. 03363), a specimen 15.25 inches long, taken off the 
shore near Ileeia, Oahu Island. 
This species must be very rare, being unknown to the fishermen and only the single specimen 
having been obtained by us.

Family LXVI. MULLID.F.- The Surmullets. 
Body elongate, slightly compressed, covered with large scales which are usually slightly ctenoid; 
lateral line continuous, the pores often branched; large scales on the head; upper profile of head more 
or less parabolic; mouth small, low, subterminal; teeth mostly small, variously placed; no canines, 
incisors, nor molars; premaxillaries somewhat protractile; maxillaries thin, nearly as broad at base as 
at tip, without supplemental bone, partly hidden by the broad preorbital; preopercleentire or slightly 
serrate; opercle unarmed or with a single spine; eye moderate, placed high; branchiostegals4; pseu¬ 
dobranchiae present; 2 long, unbranched barbels at the throat, attached just behind the symphysis of 
the lower jaw; dorsal fins 2, remote from each other, both short, the first of 6 to 8 rather high spines, 
which are depressible in a groove; anal short, similar to the soft dorsal, with 1 or 2 small spines;
