). Mouth anteroventral, anus posteroventral. Tentacle discs with rounded knobs at the edges, and the tentacles partially retracted into the mouth, making the number of tentacles difficult to calculate. Ventrolateral tube feet 40 pairs, arranged in alternating two or three rows on each ventrolateral ambulacrum. Midventral tube feet two and rudimentary, scattered along the mid-ventral ambulacrum, one positioned in the front third of the body, the other is positioned in the back third of the body, the anus surrounded by few small tube feet. Dorsal papillae roughly 18-20 on each body side, evenly distributed, measuring 4-10 cm in length, and placed in single rows along the dorsal radii. Ventrolateral papillae ~ 9-12 on each side, generally shorter than dorsal papillae, measuring 2.5-7 cm in length, arranged in single rows along the ventrolateral radii. All papillae slender and tapering from base to end.
