swollen, and closely soldered. Mouth-papille and scales of mouth-tentacles 
thick, squarish, irregular, and crowded. 
Description of an Individual (Station 320). — Diameter of disk 14 mm. 
Width of arm close to disk 2.3 mm. Mouth-papille angular, closely soldered, 
four or five on each side, and one, diamond-shaped, at angle of jaw. Mouth- 
shield large, five-sided, with blunt angle inward, and outer edge slightly curved ; 
length to breadth 2.3 : 2. Side mouth-shields narrow, of about even width, 
running along inner angle of mouth-sbield and meeting within. First under 
arm-plate three-sided, with inner sides much curved and outer edge nearly 
straight ; second and third also three-sided, having two re-entering curves on 
the lateral sides ; beyond this they become broader than long, with outer edge 
so much curved as to give them a diamond-shaped appearance. Side arm- 
plates swollen, just meeting below and separated above by upper arm-plates, 
which are rounded, with outer and inner edges slightly flattened ; farther out 
they become long hexagonal, with corners much rounded. Disk flat, covered 
with rounded raised plates, separated by deep furrows; in the centre are six 
primary plates surrounded by a row of smaller and more angular. In each 
interbrachial space above are two large plates, one on the margin. Radial 
shields blunt pear-seed shape, with the rounded end outward, separated widely 
by one large and one small plate. Genital plates composed of two or three 
pieces, the outer and principal piece long and narrow, tapering at each end, 
of which the outer is covered by a clump of small soldered papillae, which 
pass upward and form a sort of arm-comb. The rest of the lower interbrachial 
space is covered by five large and as many small plates. Arm-spines minute 
and peg-like, one half-way up the side arm-plate, and one near the junction of 
the upper arm-plate with the side arm-plate. Three large, square, close-set 
tentacle-scales on either side of pores of mouth-tentacles ; on the second pair 
one peg-like scale, and on the rest two similar scales. Color in alcohol, white.

Disk and arm plates thick, swollen, and closely soldered. Mouth-papillo and 
scales of mouth-tentacles thick, squarish, irregular, and crowded. 
Description of an Individual (off Marion Island). — Diameter of disk 9 mm. 
Length of arm 23 mm. Width of arm at disk 1.5 mm. Mouth-papillee angular, 
closely soldered, five or six on each side, and a larger, diamond-shaped, at angle 
of jaw. Mouth-shield large, pentagonal, with a long angle within and outer 
edge rounded. Side mouth-shields long, narrow, curved, and tapering towards 
either end, scarcely meeting within, First under arm-plate triangular, with 
one angle inward, outer edge straight, and lateral sides curved ; those beyond are 
wide pentagonal, with an angle within, and outer side a little curved. Side
