REPORT ON THE OPHIUROIDEA. 43 



Ophioglypha palliata, Lym. (PI. IV. figs. 4-6). 



Ophioglypha palliata, Lym., Bull. Mus. Comp. Zool., vol. v., part 7, p. G9, pL iv. figs. 98-100. 



Disk scales thin and smooth. Under arm plates, within disk, large, and touching 

 each other. Arm comb of sharp needle-like papillae, with a well-marked under comb on 

 the arm itself. 



(Type specimen from Station 164a). Diameter of disk 10"5 mm. Width of arm close 

 to disk 2 '5 mm. Five or six small mouth papillae 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 corners rounded. Length to breadth 2"5:2. Side mouth shields long and 

 narrow, meeting within ; broadest at their outer end, where they join the side arm plates. 

 First under arm plates irregular, transverse oval ; the second similar, but larger ; those im- 

 mediately beyond are transverse diamond shaped, with much rounded angles. Side arm 

 plates broad and thin, not meeting below till beyond the disk, widely separated above by 

 the upper arm plates, of which the first one is small and triangular, the second quad- 

 rangular, with the outer edge widest and curved, and inner edge straight. Upper surface 

 of disk, which is smooth and even, covered with thin, fine, ill-defined curved scales ; the 

 radial shields are longer than wide, with edge much rounded, separated their entire 

 length by small scales. Under surface covered by rows of scales somewhat larger than 

 those above. Genital scales wholly covered by the scaling, except above, where they 

 support an arm comb of sharp, slender papillae ; their free edge below carries a row 

 of small conical papUlae. Three tapering arm spines, upper one longest, second and third 

 about equal. Three or four small rounded tentacle scales on each side of the mouth 

 tentacles, second and third pores having three on each side; those just beyond with 

 four short sharp scales on the inner side. Colour in alcohol, grey. 



Station 164«.— June 13, 1874 ; lat. 34° 13' S., 34° 19' S., long. 151° 38' E., 151° 31'

Ophioglypha lepida, Lym., Bull. Mus. Comp. ZooL, vol. v., part 7, p. 70, p.l iii. figs. 71-73. 



Four arm spines ; one long and high up, three short and low down. Radial shields touch- 

 ing without ; disk scales angular. Disk thin, with rather delicate scales. Arms slender. 



(Type specimen from Station 46.) Diameter of disk 9 mm. Width of arm close to 

 disk 1 "5 mm. Mouth papillae, three to four on each side, short and square, with a larger 

 pointed one at apex of jaw. Mouth shield wide pentagonal, with an obtuse angle inward, 

 outer edge slightly curved, and outer corners rounded ; length to breadth 1:1. Side 

 mouth shields long narrow, wider without, tapering inward where they meet. First under 

 arm plate broad triangular, those beyond pentagonal, with obtuse angle inward, lateral 

 sides re-enteringly curved and outer edge slightly curved ; beyond the disk they gradually
