Macrurus liocephala Gunther, Deep Sea Fishes, Challenger, p. 145, pi. xxxvm, tig. a, 1887; near Yokahama in T.SJ5 
fathoms; middle Pacific in 2,050 fathoms. 
This species is known to us solely from Dr. Gunther’s figure and description.

Coryphosnoides Gunner, Trondhj. Selsk. Skrift., m, 50, 176!j (rupestris). 
Branckiostegus Ratinesque, Analyse de la Nature, 1810, 86 (substitute for Coryphsenoides) . 
Snout short, obtuse, high, obliquely truncated, soft to the touch, except its bony center; mouth 
1 troad, terminal, its cleft lateral; head without prominent ridges, membrane bones of side of head rather 
soft, but not papery; teeth villiform in both jaws, those in outer series of upper jaws somewhat enlarged. 
Scales spinous, second or elongate dorsal ray finely serrated in front, the seme sometimes scarcely 
appreciable. Lower jaw with a barbel at tip. Deep sea. Close to Macrourus, differing in the larger 
terminal mouth.

Conjphxnoidcs altipinnis Gunther, Ann. & Mag. Nat. Hist. 1877, xx, p. 139; south of Tokyo in 1,879 fathoms; off Japan in 565 
fathoms. 
Macrurus altipinnis Gunther, Deep Sea Fishes, Challenger, 1887, p. 138, pi. xxxix, fig. A, three specimens. 
This well-marked species is known to us from Dr. Gunther’s description and figure. 
(Altus, high; pinna, fin.) 
92. Coryphsenoides awae Jordan & Gilbert, new species. 
Type No. 8547, L. S. Jr. Univ. Coll., 620 mm. long, from off Nanaura in Awa at the entrance of 
the bay of Tokyo; presented by the Imperial University. 
First dorsal 11 , 9; ventrals 7 and 8 respectively; pectorals 21. Head 5.3 in total length, equaling 
depth. Seven scales in a vertical series bet ween Jateral line and median line between dorsals. 
Head and body high and compressed, greatest depth of head at posterior end of occipital crest 
equaling length of head anterior to upper end of preopercle; snout short and gibbous, its outline 
everywhere convex, its extreme tip formed by a small protruding tubercle; supraocular region 
depressed, longitudinal profile strongly concave, nearly flat transversely; head everywhere firm, mucus 
canals comparatively little developed, sides of head nearly vertical, suborbital ridge evident but very 
low, ending on middle of cheek; posterior nostril very large, anterior small, roundish. 
Eye 4.33 in head; interorbital width 5; length of snout 3.4; posterior border of orbit in middle of 
length of head; preopercle not produced at angle; posterior margin vertical and convex. 
Mouth but little overpassed by snout, the axial projection of which does not exceed one-half 
diameter of pupil; mouth nearly horizontal, comparatively short, the maxillary not passing vertical 
from middle of orbit; width of mouth at angle slightly exceeding length of cleft; mandibular barbel 
short, four-fifths diameter of pupil; teeth slender, in moderate villiform or cardiform bands in each 
jaw, bands tapering laterally, but not to a single series; outer teeth not at all enlarged. Gill-opening 
wide, membranes anteriorly united with isthmus, apparently without free fold along posterior margin. 
Anterior gill-slit contracted to little more than a pore just below angle of arch, its length less than half 
diameter of pupil. Posterior gill-slit half diameter of eye. Pseudohranchke wanting.
