JAPANESE FISHES. 
607 
Scales very small, thin, caducuous, fallen in most of our specimens. As usual in the genus, they 
are unarmed, marked with extremely fine concentric strife. The lateral line runs posteriorly along 
middle of sides, rising anteriorly in a wide, low arch, the chord of which nearly equals length of head; 
entire head covered with scales (except gill and gular membranes) ; smaller than in M. bowersi, being 
little larger than the scales on sides. 
Light brownish on head and body, breast and belly little darker except in young specimens, 
where the belly is blue-black and the breast brown; head light brown like body; opercles blackish in 
young. Rows of very small brown spots on top and sides of head, and along the rami of mandibles in 
some specimens; mouth and gill cavities and peritoneum black; fins dusky. 
( dvrpodr / ;, full of cavities, from the spongy head.) 
Station 3696, Sagami Bay, 501 to 749 fathoms; station 3711, Suruga Bay, 500 to 677 fathoms; sta- 
tion 3736, Suruga Bay, 480 to 599 fathoms.

Of this species, well figured and described by Dr. Gunther, three large specimens were dredged in 
Sagami Bay, by the Albatross, near the original locality.
