FISHES OF HAWAIIAN ISLANDS. 
673 
Scales large, adherent, those on anterior part of head greatly reduced in size; they densely cover 
entire head, including snout, the suborbital region, and the posterior 0. 7 of the mandibular rami; gular 
and gill-membranes bare; on middle of sides each scale bears numerous very short appressed spines, 
arranged usually in 16 or 18 parallel series; there is some irregularity in the arrangement of the spines, 
which sometimes break rank and show a tendency to form in quincunx order; in the smaller scales of 
snout and interorbital area the spines are greatly crowded, stand out vertically from the scales, and 
are sometimes arranged in diverging series; there are 26 series of scales in advance of origin of second 
dorsal fin. 
Fig. 263 . — Macrourus longicirrhus Gilbert, new species. Type. 
Color uniform dark brown or purplish brown on head, body, and fins; gill-cavity similarly colored; 
inside of mouth lighter; peritoneum white, or only faintly dusky; barbel and ventral filaments white, 
dorsal filament colored like rest of fin. 
. Only the type known. 
Ccelorhynchus gladius Gilbert & Cramer. 
Six specimens of this rare species were secured. In the longest specimen, 238 mm., the scales 
along back near first dorsal fin have 40 to 50 minute equal spinelets, arranged in about 10 series, 
which, are parallel throughout; the spines are thus much more numerous than in the smaller type 
specimen and in other smaller specimens before us. In the figure of the type cited below, the enlarged 
cut of the scale is very poor and misleading, the spines being much smaller than there shown, and 
more closely set. The scales on the head have the spinelets still more minute and more numerous, 
arranged in slightly radiating series, and giving a rough shagreen-like texture to the head. 
The following additions and corrections may be made to the type description: Barbel variable in 
size, and may equal 0.4 diameter of orbit; gill-membrane with a very narrow free margin behind; outer 
gill-slit not pore-like, but a slit 0.4 diameter of orbit; distance from inner base of ventrals to origin of 
anal 0.3 length of head; vent at posterior end of a well-marked naked fossa; lining of mouth whitish 
anteriorly, becoming dusky toward gullet; gill-cavity slightly dusky, but not black, a dark blotch on
