Ambb boot-shaped, each bearing a large, dorsally sloping, podial basin shared with the Adambb and partly by the next distal Amb. Adambb greatly expanded abradially, with expanded parts set oblique to radial line and abutting each other with large flat surfaces, with pair of larger spines dorsally and four small spines along distal margin ventrally, the number of spines decreasing distally along the ray. Mouth frame of distally expanded Ambb2 lying over short Ambb3 and 4 dorsally; Ambb, as long as Ambb2; torus on proximal face of each Ambbl, bear- ing few long spines projecting into mouth.
