irregularly alternating with the larger ones in both jaws. Posterior third of each jaw toothless; 
palate smooth. Anterior nostril with an overarching flap or short tube; posterior nostril without tube. 
Eyes elliptical, nearly even, long axis of lower eye very oblique. Oblique diameter of upper 
orbit 3.75 in head; snout short, five-sevenths diam- 
eter of upper eye. Interorbital space narrow, grooved, 
the width one-fifth diameter of upper eye. 
Dorsal fin beginning above anterior nostril, the 
first few rays slightly displaced toward the blind 
side; pectoral narrow, pointed, about 1.75 in length 
of head, that of blind side apparently shorter; caudal 
lanceolate in a young individual (mutilated in adult), 
the middle rays 1.25 in head. 
Jaws, snout, and interorbital space naked; head 
and body elsewhere covered with minute cycloid 
scales; lateral line nearly axial, its anterior arch low, 
above the head, the posterior downward curve abrupt, 
above base of pectoral; length of arch nearly equal to 
half depth of body. r 
Color in alcohol, head and body light brown, the h 
outlines of the scales dusky, the wide bases of dorsal 
and anal fins semitranslucent; abdomen in the adult ta 
with narrow vertical stripes of blue-black, alternating 4 
with wider muscular bands which are of the ground- |. 
color; head and anterior median portion of trunk 5 
with faint darker brown spots about one-third size * 
of pupil. In addition to these, the median part of 3 
body is marked with about 45 larger round spots, 5 
darker than the others, but still faint and ill-defined. S 
These are nearly as large as eye, and are arranged on £> 
anterior part of trunk in 7 lengthwise series, all but 3 <jf 
of which gradually disappear on tail. The larger y 
spots are much more distinct in the young than in a 
adults. Mouth and gill-cavity white; peritoneum | 
black; fins dusky. Taken in deep water about the 5 
Hawaiian Islands at depths of 238 to 344 fathoms. 4' 
Found only in the Pailolo Channel and its ap- S 
proaches, and in the southerly continuation of the jjf 
Kaiwi Channel, where it was originally obtained. ■< 
Three specimens 7 to 10 inches long, from stations ? 
3472 and 3476, were obtained by the Albatross in 
December, 1891, while engaged in surveying a cable 
route between California and Honolulu. Other ex- 
amples were collected by the Albatross in 1902.
