BULLETIN OF THE UNITED STATES FISH COMMISSION, 
! 
As in other species of the genus, there are two small lens-like bodies on the mid-ventral line, one 
immediately in front of anal opening, the other on middle of breast. 
Color light-grayish or brownish above, silvery on lower half of sides; sides of body and tail marked 
by rather coarse brown specks, which form a definite line along middle of sides. A strip along bases 
of dorsal and anal fins is devoid of specks, a sharp line between this and the spotted area often marked 
by a series of coarser dots; dots on sides of tail arranged partly in oblique lines which seem to corre- 
spond with those separating the myotomes; a dark vertebral line between dorsals and a dark spot at 
base of each ray of second dorsal and anal. The first dorsal occupies a conspicuous colorless area of 
the back which is margined with dusky; a dark blotch behind occiput; tip of snout faintly dusky. 
Upper jaw black in its anterior two-thirds, the lower jaw in its anterior third; posterior portions of 
both jaws white. Gular membrane silvery, with a fine network of dark lines, most of which are short 
and transverse, arranged in a right and a left series, those of each series united by a lengthwise com- 
missure. Lateral portions of isthmus, concealed by the gill flap, bright silvery, crossed by fine parallel 
hair lines of brownish purple. This striated area extends backward above and behind hase of vent- 
rals; breast and belly purplish-black. The roof of mouth shines with a silvery luster. Mouth and 
gill cavity light in color, region about entrance to gullet blackish. Peritoneum silvery, overlaid with 
brown. Fins translucent, unmarked. 
One specimen was found in the Tokyo Market by Jordan & Snyder; the others were dredged by 
the Albatross at station 3697, Sagami Bay, 120 to 265 fathoms, and station 3707, Saganii Bay, 63 to 75 
fathoms.

Macruroplus Sleeker, Vers). Med. Akad. Wet. Amsterd., vm, 1874, 369 (terrains). 
Macrurus Gunther, Cat., tv, 392, 1862; corrected spelling. 
Snout broadly conical, high, projecting beyond mouth; mouth moderate, its cleft horizontal; 
U-shaped, entirely inferior; teeth in both jaws in villiform bands, those of outer series not enlarged, 
head with roughened bony ridges, one of which, on the suborbital and preorbital, is more or less 
prominent; eyes very large; scales imbricate, very rough, keeled. Dorsal spine long, serrated on the 
anterior edge. Deep water fishes. (juaKpo c, long; ovpa, tail, hence correctly written Macrurus, but 
Macrourus is the original name as given by Bloch. ) 
a. Snout conical, overhanging the mouth, much longer than eye; scales each with a compact mass of spinules; 
G scales between lateral line and spinous dorsal; dorsal spine and first ventral ray filamentous nasvivs, 99 
an. Snout short, little longer than eye, not much overhanging the mouth; 7 or 8 scales above lateral line; each 
scale with 5 ridges; dorsal spine and first ventral ray produced as 'per, 100 
99. Macrourus nasutus (Gunther). 
Coryphxnoidcs nasutus Gunther, Ann. & Mag. Nat. Hist., xx, 1877, p. 440. 
Macrurus nasutus Gunther, Deep Sea Pishes, Challenger, 1887, p. 132, pi. xxx, fig. B; south of Tokyo in 565 fathoms; 
off Enoshima in 345 fathoms. 
Short snout with a terminal and a pair of lateral spinous tubercles; mandibular rami are com- 
pletely invested in scales; interorbital width slightly exceeding two-thirds the vertical diameter of 
orbit, which is contained 4.33 to 4.5 times in length of head. The first dorsal contains 10 rays, the 
second filamentous and well serrate, the pectoral 21 to 23, and the ventrals 9 (not 10, as stated by 
Gunther), the first ray filamentous. Scales everywhere covered with closely packed long, slender 
spines, posterior spines well overlapping margin of scale; while not in longitudinal rows, these spines 
are definitely arranged in quincunx order, as can be readily seen on viewing them from different 
angles. 
The alcoholic specimens are all very light olive-gray, fins blue or blue black; lips black; mouth, 
gill-cavity, and peritoneum, black; opercular membrane more or less black. 
Fifteen specimens, each about 15 inches long, were dredged by the Albatross in Sagami Bay, near 
Enoshima, at station 3696, 501 to 749 fathoms; station 3699, 400 to 726 fathoms; station 3711, 500 to 
677 fathoms. 
Another, presented by Kuina Aoki, came from off the shore of Izu.
