MUSEUM OF COMPARATIVE ZOOLOGY. 69. 
Ophioglypha flagellata sp. nov. 
Plate II. Figs. 49-51. 
Special Marks, —Disk covered with smooth skin, through which the very 
small scales are scarcely or not at all visible. Arm-spines long, broad, and flat. 
Description of an Individual (Station 232). — Diameter of disk 18 mm. 
Width of arm without spines 4 mm.  Mouth-papillze four or five on each side, 
small, tooth-like, separated, growing larger towards the apex of the jaw, where 
there is one large and club-shaped resembling the teeth above it, Mouth-shield 
small, short heart-shape, with projecting corners and angle inward ; length to 
breadth 9.7: 3. Side mouth-shields long and narrow, wider without than 
within, where they do not quite meet. First under arm-plate broader than 
long, triangular or rudely hexagonal, with angles much rounded ; the plates 
beyond are much wider than long, bounded within by a blunt angle and with, 
out by a curve having a little peak at its apex. Side arm-plates rather thin, 
not meeting till some way beyond disk, widely separated above by upper 
arm-plates, which are hexagonal, much broader than long, very flat and thin, 
with outer and inner edges straight, and ill-marked lateral angles. Disk flat, 
covered with a thick skin, under which the thin small scales are scarcely, or 
not at all, distinguishable. Radial shields very small, rounded, and widely 
separated; length to breadth 1: 1.5. Interbrachial spaces below covered by 
regular rows of very fine, minute scales, extending quite to the margin. Genital 
scales long and very narrow, almost concealed by the disk-scales ; along the 
free edge is a row of very fine, delicately pointed papille, which grow longer 
as they pass upward to make a short arm-comb. Arm-spines longer than the 
joints, flat spatula-shape, arranged in a cluster of three just outside the tentaele- 
pores; of which those of the mouth-tentacles are very large, and have six or 
seven thin, flat scales on each side; the next three have three long thin flat 
scales on the inner side, and one or two very small slender ones on the outer 
side, beyond this three only, on the inner side. Color in alcohol, disk gray, 
upper arms yellow brown. 
Station 232, 340 fathoms, 2 specimens. 
Ophioglypha palliata sp. nov. 
Plate IV. Figs. 08-100. 
Special Marks. — Disk-scales thin and smooth. Under arm-plates, within 
disk, large and touching each other. Arm-comb of sharp needle-like papilla, 
with a well-marked under comb on the arm itself. 
Description of an Individual (Station 164 a). — Diameter of disk 10.5 mm. 
Width of arm close to disk 2.5 mm. Five or six small mouth-papille on 
each side, the two outermost being short and blunt, the next three or four 
sharply pointed, while the one at the apex of the jaw is large and rounded 
at the end, Mouth-shield pentagonal with a blunt.angle inward, and outer
