FISHES OF HAWAIIAN ISLANDS.

without cross-bars except on caudal peduncle and between dorsal and anal fin, where there are light 
bars which tend to break up into white spots. The caudal usually has the 2 black spots, though the 
lower one is often absent. 
The color of this species seems subject to great variation. Garrett, in Fische der Stidsee, figured 2 
forms, one a uniform lemon-yellow and another light brown with 5 or 6 rosy-brown longitudinal stripes 
each less than pupil in width; a narrow line of same color on caudal peduncle with a broader crossbar 
at each end and one at its middle; head pale rosy with 3 deeper rosy oblique bars on snout; fins all 
pale rosy; middle caudal rays scarcely rosy; a black spot on maxillary, one on base of ventral and 2

on caudal fin. In the yellow figure there is a black spot on maxillary and one on upper caudal rays, 
but none below nor on ventral. 
This species is fairly abundant at Honolulu, where specimens were obtained by Jenkins in 1889, 
by the Albatross in 1896 and 1902, by Wood in 1898, and by us in 1901. The Albatross obtained it also 
at Laysan, and it occurs at Johnston Island.

Family XXXVI. FISTULARIILLJi. — The Cornet-Fishes. 
Body extremely elongate, much depressed, broader than deep; scaleless but with bony plates on 
various parts of the body, mostly covered by the skin; head very long, the anterior bones of the skull 
much produced, forming a long tube, which terminates in the narrow mouth; this tube formed by the 
symplectic, proethmoid, metapterygoid, quadrate, palatines, vomer, and mesethmoid; both jaws, and 
usually the vomer and palatines also, with minute teeth; membrane uniting the bones of the tube 
below, very lax, so that the tube is capable of much dilation; post-temporal coossified with the 
cranium; branchiostegals 5 to 7; gills 4, a slit behind the fourth; gill-membranes separate, free from 
the isthmus; gillrakers obsolete; basibranchial elements wanting; pseudobranchiae present; air-bladder 
large; spinous dorsal entirely absent; soft dorsal short, posterior, somewhat elevated; anal fin opposite 
and similar to soft dorsal; caudal fin forked, the middle rays produced into a long filament; pectorals 
small, with a broad base, preceded by a smooth area as in Gasterosteidie; pectoral ossicles 3; inter- 
clavicles greatly lengthened; supraclavicles very small; ventral fins very small, wide apart, abdominal 
(through partial atrophy of the girdle, by which they lose connection with the interclavicles), far in 
advance of the dorsal, composed of 6 soft rays; pyloric coeca few; intestine short; vertebrae very 
numerous (4-j-44 to 49-j-28 to 33); the first 4 vertebrae very long. Fishes of the tropical seas, related 
to the sticklebacks in structure, but with prolonged snout and different ventral fins. A single genus, 
with few species.
