swollen, and closely soldered. Mouth-papillae 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-papillae 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 luoutli-shields narrow, of about even width, 

 running along inner angle of mouth-shield 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 

 60 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. Kadial 

 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.

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. Moutli-papillae angular, 

 closely soldered, five or six on each side, and u 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 

 cither end, scarcely meeting within. First under arm-plate triangular, with 

 one angle inward, outer edge straight, and lateral siiles curved ; those beyond are 

 wide pentagonal, with an angle within, and outer side a little curved. Side
