, long, broken near tip. Disc circular in outline, dorsal surface almost flat, slightly depressed towards centre; ventral surface convex, arching upward towards the relatively thin margin. Dorsal surface of disc with a very thin skin in wet specimen, thin imbricating scales and plates clearly visible when dried; primary plates larger and distinct; centrodorsal slightly ovoid, surrounded by a circlet of small scales, mostly widest proximally, and in 2 interradii the scales are enlarged; the primary radials are just outside this circlet and are transversely ovoid; both centrodorsal and the primaries have a minute tubercle, central on the centrodorsal, slightly distal on the radials; beyond the radials are 3 scales in a transverse row, the outer 2 larger and just touching the radial shields; 2 scales followed by 1 more distal separate the radial shields for most of their length. Radial shields longer than wide, slightly curved, extend inwards for almost 1/2 disc radius, in contact at extreme outer edge, where one may overlap the other. No arm comb. In the interradii, scales become larger towards margin; space between the inner ends of radial shields is occupied by one larger plate, rounded distally, at margin is a small plate flanking shields, the intervening space taken by a larger transversely elongate plate. Ventral surface of disc with thin, imbricating scales. Genital clefts extend almost to disc margin; genital scale 23 pieces, sutures indistinct; no genital papillae. Oral shield wider than long, acutely pointed proximally, distal margin broadly rounded; adoral shields extend to first lateral armplate, curved and meet within, almost the same width throughout. Oral plates with a pointed apical papilla at tip and 67 oral papillae, proximal 34 pointed, the rest becoming flat and truncate or with 2 distal points, as though 2 papillae are united. Distal end of oral slit lacks papillae. Second oral tentacle­pore opens outside of oral slit, with 34 low, flat papillae on each margin, these rounded distally and almost confluent.

No papillae on distal margin of dorsal armplates. First lateral armplate does not meet the dorsal plate, the space being skin­covered (this is not a consistent feature on all specimens); proximal plates have 56 finely thorny tapering armspines, upper 12 equal to 2 arm segments; spine length decreases ventrally, lowest is just less than one segment, has a slightly enlarged base and is almost thorny. From about the sixth plate they project slightly laterally, have 4, then 3 armspines, upper equal to one arm segment, lower sometimes with a slightly hooked tip. Ventral armplates separated from the third; first has a very short, straight proximal margin and is broadly rounded distally; others have an acute proximal point, and a similar rounded distal margin.
