Macrurus trichiurus sp. n. 
Brenan os LL ae iay V8: 
The shape in this species is much like that of I. convergens, from which 
it may be distinguished by the smaller number of rays in the ventrals, the few 
serrations on the second dorsal spine, and by the great length and slender- 
ness of the caudal section. Body compressed, caudal extremity very slender, 
threadlike. Head two thirteenths of the total length. Snout broader than 
the interorbital space, the ridges of the top diverging forward to the two prom- 
inent lateral angles; median angle protruding, apex equidistant from orbit 
or maxillaries; length equal to three fifths of that of the orbit. Orbit large, 
two and two thirds times in the length of the head, half of the interorbital 
space. Suborbital ridge prominent, sharp, subtending the entire orbit. Mouth 
medium; maxillary extending below two thirds or more of the orbit. 
Teeth small, equal, in villiform bands. Dorsal origin above the base of the 
pectoral ; first spine short; second spine longest with a filament and three 
or four spinules. Second dorsal low, feeble. Origin of anal slightly back- 
ward of the hind end of the base of the first dorsal. Vent a short distance 
forward of the first anal ray, opposite the midlength of the ventral fins. 
Ventrals small, originating somewhat farther backward than the dorsal, 
below the bases of the pectorals. Pectorals small, two thirds as long as the 
head. Scales small, anteriorly in the median line each bears a short spine 
and directly behind this a larger one extended out and backward beyond 
the scale margin. Toward the back some scales have an additional, and 
shorter, row of spines on each side of the median, the three rows diverging 
backward, 
Black ; muscular portions lighter, reddish brown.
