Radial articular facet rather large, sloping slightly outward; interarticular ligament fossae large. Radials and arms different in size, more or less distinctly arranged as group of 3 larger arms and group of 2 smaller arms. Arms 10, stout, coiled inward, forming fistlike cover over adoral surface; each branch with as many as 25 to 30 brachials forming spiral and meeting laterally as cover over adoral side of cup when retracted. Proximal 3 to 10 secundibrachials large, succeeded by distinctly smaller brachials. Some brachials may be irregular, commonly smaller, and triangular to fit within cover. [details]
