5562C7A96CDF514A9DE048A3D4ACE624.taxon	description	Description. Single specimen (d = 3.4 cm, H = 1.6 cm). In situ, the body is reddish brown, rounded and flattened (Fig. 33 A, B). Spines are the same reddish brown colour of the body; oral primary spines are encased by a fleshy, clear sac, swollen and brighter at the tip. The test and covering skin are very thin and gonads are visible through; primary spines are projected upwards and tube feet extending downwards from the lower half of the body. Whole abactinal surface (ambulacral and interambulacral) covered by primaries arranged in irregular lines along the median lines of the plates, with few secondaries or militaries near ambitus (Fig. 33 C). Claviform (globiferous) pedicellariae carries two saccules and two valves. Before preservation, colouration was bright orange.	en	Bribiesca-Contreras, Guadalupe, Dahlgren, Thomas G., Amon, Diva J., Cairns, Stephen, Drennan, Regan, Durden, Jennifer M., Eleaume, Marc P., Hosie, Andrew M., Kremenetskaia, Antonina, McQuaid, Kirsty, O'Hara, Timothy D., Rabone, Muriel, Simon-Lledo, Erik, Smith, Craig R., Watling, Les, Wiklund, Helena, Glover, Adrian G.

90646AB61F165E90A4DCB58E0252598A.taxon	description	Description. Single specimen, with white arms and greyish blue disc in situ (Fig. 52 A). Disc is flattened and somewhat pentagonal; brownish when alive and white after preservation (Fig. 52 B, D). Dorsal disc surface is covered by minute, thin, imbricated scales covered by a thin skin, not obscuring the scale margins; few granuliform spinelets scattered on the dorsal surface (Fig. 52 B). Small, oval, radial shields, approx. as long as wide, arranged diagonally and touching proximally; distal margin extends beyond the disc margin (Fig. 52 D). Ventral surface of the disc covered by scales similar to the ones on the dorsal surface, but lacking spinelets; gonads are visible through the thin scales (Fig. 52 C). Each jaw bears two or three apical papillae, and three oral papillae on each side; two distalmost are block-shaped while the third distalmost is spiniform. Oral shield is triangular, longer than wide, rounded proximally; separated from the first lateral arm plate by the wing-shaped adoral shield. Supplementary oral shield, wider than long, located on the distal margin of the oral shield. Two adoral shield papillae, with one placed in the middle of each shield, resembling arm spines in shape and size. Arms are slender, ≥ 3 x as long as the disc diameter. Dorsal arm plates triangular, with rounded distal margin and slightly convex distal edge, separated from preceding plates by lateral arm plates; first two dorsal arm plates absent but arm segments covered by thick skin with smaller plates embedded (Fig. 52 D). Adjacent lateral arm plates are slightly separated by soft tissue; each lateral arm plate bears four long arm spines, similar in size; only two arm spines present in the first three arm segments and three on subsequent two arm segments. First ventral arm plate is small, broad and triangular, with the rest being pole-axe shaped and separated from the preceding plate except for the first two segments. Tentacle pores are large throughout the entire length of the arm, with no tentacle scales except for the first arm segment, where there is one attached to the lateral arm plate and resembles a small arm spine.	en	Bribiesca-Contreras, Guadalupe, Dahlgren, Thomas G., Amon, Diva J., Cairns, Stephen, Drennan, Regan, Durden, Jennifer M., Eleaume, Marc P., Hosie, Andrew M., Kremenetskaia, Antonina, McQuaid, Kirsty, O'Hara, Timothy D., Rabone, Muriel, Simon-Lledo, Erik, Smith, Craig R., Watling, Les, Wiklund, Helena, Glover, Adrian G.

362E33D763085457B57D3BE76EAFB1AB.taxon	description	Description. Single specimen (disc diameter = 9 mm, maximum arm length = 25 mm). Disc subpentagonal, flattened (Fig. 51 A, B). Dorsal disc surface covered with numerous, imbricated, delicate disc scales, which are irregular in shape, decrease in size distally and extend dorsally onto the first arm segments (Fig. 51 C). Radial shields and genital plates apparently absent. Disc covered by thin skin, not obscuring the scales. Ventral surface of the disc covered by scales similar to the dorsal disc scales (Fig. 51 D).

Each jaw bears a large, spiniform, apical papillae and a smaller adjacent one on each side; additionally, there are two to three modified papillae placed distally on each side of the jaws, block-shaped, the distalmost being wing-shaped. Genital slit is not conspicuous. Arms are thin, longer than twice the disc diameter (Fig. 51 A, B). Dorsal arm plates are triangular, wider than long, with pointed proximal and straight distal edges; separated by lateral arm plates and therefore not overlapping with preceding dorsal arm plate (Fig. 51 C). Arm spines are conical, tapering distally but with rounded tips; two arm spines on first three arm segments, three arm spines on next three segments and four on the rest; middle arm spine is the longest, but all are approx. the same length, approx. half the length of one arm segment. First ventral arm plate is triangular, while the rest are pole-axe shaped, approx. as long as wide, separated from the preceding plate by the lateral arm plates except for the first two ventral arm plates (Fig. 51 D). Tentacle pores are large and evident throughout the entire length of the arm. Three flattened, rounded, large adoral shield papillae. First four arms segments with two large papilliform tentacle scales attached to the lateral arm plate; subsequent arm segment with a single tentacle scale; tentacle scales absent on the remaining arm segments.	en	Bribiesca-Contreras, Guadalupe, Dahlgren, Thomas G., Amon, Diva J., Cairns, Stephen, Drennan, Regan, Durden, Jennifer M., Eleaume, Marc P., Hosie, Andrew M., Kremenetskaia, Antonina, McQuaid, Kirsty, O'Hara, Timothy D., Rabone, Muriel, Simon-Lledo, Erik, Smith, Craig R., Watling, Les, Wiklund, Helena, Glover, Adrian G.

07FCEAB9BF5D596C98138C6015EEB01E.taxon	description	Description. Two specimens, with greyish disc and pale arms in situ (Fig. 53 A, B). Disc rounded to pentagonal, flattened, with slender, long arms, at least disc diameter (disc diameter = 2.6 cm, arm length = 13.1 cm; Fig. 53 C, D). Dorsal disc surface covered by irregular, larger disc scales surrounded by small, imbricated disc scales that also vary in size and shape. Radial shields are small, subtriangular, almost as wide as long. Arm combs visible under the radial shields; with five short block-like arm-comb spinelets, not continuous on dorsal midline. Ventral surface of the disc is covered by large, imbricated scales, increasing in size towards the margin of the disc (Fig. 53 F). Oral plates with 6 - 8 oral papillae, proximalmost are pointed, becoming block-like towards the distal side of the oral plate. Oral shield approx. as long as wide, subpentagonal, with somewhat concave proximal margins, a convex distal margin, and with lateral margins slightly constricted in the middle, where the genital slit begins. Adoral shields touching proximally, with a similar width all along, and separating the oral shield from the first lateral arm plates. Genital slits run from the middle of the oral shield to the disc margin, bordered by a continuous row of block-like genital papillae that continues dorsally as an arm-comb. Dorsal arm plates fan-shaped, contiguous. Lateral arm plates bear three short (less than a third of the length of the arm segment) arm spines from the third arm segment; two are located ventrally, very close together, and one located dorsally, approx. halfway through the lateral arm plate; first arm segment bears two arm spines, the second two or three spines. Ventral arm plate trapezoidal, wider than long, only touching the preceding plate only on first three arm segments, after which they are separated by the lateral arm plates and become fan-shaped to rhomboidal, more than twice as wide as long, with pointed proximal edge and rounded distal margin. Towards the distal end of the arms, the second lowest spine is modified into a hyaline hooklet (Fig. 53 E). Tentacle pores only on most proximal segments (8 - 11), with six ventral and six lateral tentacle scales on first arm segment and decreasing in number until there is a single, very small, spiniform, tentacle scale remaining for most of the arm length.	en	Bribiesca-Contreras, Guadalupe, Dahlgren, Thomas G., Amon, Diva J., Cairns, Stephen, Drennan, Regan, Durden, Jennifer M., Eleaume, Marc P., Hosie, Andrew M., Kremenetskaia, Antonina, McQuaid, Kirsty, O'Hara, Timothy D., Rabone, Muriel, Simon-Lledo, Erik, Smith, Craig R., Watling, Les, Wiklund, Helena, Glover, Adrian G.
