Ophioglypha inornata sp. nov. 
Plate II. Figs. 26, 27. 
Special Marks, — Side mouth-shields small. Mouth-shield broader than 
long, with a peak inward. Disk and arm plates thick, swollen, and closely 
soldered. Mouth-papille and scales of mouth-tentacles thick, squarish, irreg- 
ular, and crowded. 
Description of an Individual (Station 106),— Diameter of disk 10 mm. 
Length of arm about 23 mm. Width of arm close to disk, without spines, 
2 mm. Five or six short, bead-like, closely soldered mouth-papille on each 
side, with one much longer at apex of jaw. — Mouth-shields broader than long, 
small, rounded. triangular, with angle inward, and outer edge eurved. Side 
mouth-shields short, pointed oval, occupying inner sides of the mouth-shield 
and meeting broadly within, First under arm-plate rounded, with a long 
curve within and an obtuse angle without ; second. pentagonal, with an angle 
inward, outer side wide, and laterals re-enteringly curved ; beyond these the 
plates become broader than long, with an angle within and a eurve without, 
Side arm-plates thick, slightly swollen, meeting broadly below; separated above 
by upper arm-plates, which are thick, rather small, of a rounded diamond- 
shape, and as long as broad. Disk rather thick, swollen, covered with thick, 
minutely tuberculous plates. Radial shields irregular in form, inner edges 
nearly eireular or oval, diverging inward, where they are separated by a single 
row of three scales ; in each interbrachial space is a marginal plate connecting 
the radial shields, In centre of disk above are six round, well-marked. pri- 
mary plates, separated from each other and from the radial shield by single 
lines of much smaller plates. Interbrachial space below covered chiefly by 
a large marginal plate, and two smaller between it and the mouth-shield. 
Genital plates short, thick, broader within, tapering outward, where they bear 
small, irregularly placed papilla, which make above a sort of arm-comb, Arm- 
spines minute and hard to see, one near upper arm-plate and two or three near 
the under. 'Tentacle-scales minute; on the pores of the mouth-tentacles are 
four on one side and three on the other; the second pore, which is near the 
inner end of the arm-plate, has only three; and the third two. Color in 
aleohol, gray.
