FISHES OF HAWAIIAN ISLANDS. 
669 
First dorsal u, 10; ventral 9; pectoral 20 or 21; 14 scales in a series downward and backward 
from origin of first dorsal to lateral line, 11 between lateral line and origin of second dorsal (8 in if. 
holocentrus) . 
Head short and high, compressed, the greatest depth contained 1.2 times in its length; upper pro- 
file nearly straight from dorsal fin to snout, a very slight depression above orbits; profile of snout gently 
decurved to rostral tubercle, descending thence in a vertical line to front of premaxillaries; head firm, 
without conspicuous mucous cavities, the scales everywhere firmly adherent; snout terminating antero- 
superiorly in a tubercle covered with spines radiating in all directions from the center; a pair of smaller 
spinous tubercles are separated from the first by less than half its diameter; suborbital flat, without 
ridge; interorbital space narrow, very slightly concave, its width slightly less than length of snout, 0.8 
diameter of orbit; upper rim of orbit encroaching on upper profile; snout 0.25 length of head; eye 
circular, 3.3 in head; distance from rostral tubercle to premaxillaries 0.2 length of head; front of 
premaxillaries far in advance of nostrils; maxillary scarcely reaching vertical from front of pupil, 
contained 3.25 in length of head, and equal to width of mouth; teeth in very wide villiform bands in 
both jaws, the outer series in the upper jaw scarcely enlarged; length of barbel 0.7 diameter of orbit; 
least width of the suborbital 0.3 diameter of orbit; preopercular angle not produced, the posterior 
margin nearly vertical, convex in its upper half, concave immediately above the angle. 
Fig. 260. — Macrourus burrcigei Gilbert, new species. Type. 
First dorsal fin very, long; second dorsal spine large, provided with 17 rather fine serrations 
evenly distributed for its entire length, its flexible portion short, its tip scarcely projecting beyond that 
of the first succeeding ray; total length of spine equaling distance from tip of snout to base of upper 
pectoral ray; rays of second dorsal very short and inconspicuous, the base of the first ray reached by 
the seventh ray of first dorsal; interspace between dorsals equal to base of anterior fin; first anal ray 
under middle of anterior dorsal, its distance from base of inner ventral ray one-half distance from 
latter to edge of gill-membrane; inner ventral ray reaching anal origin, the other rays extending well 
beyond it, the filamentous outer ray reaching base of fifteenth anal ray, its length 1.1 in that of head; 
pectoral wide, extending to opposite eleventh anal ray, its length 1.45 in head; a small naked pit on 
middle line of breast between the outer ventral rays.
