Fig. 5. Dipsacaster fisheri, new species, holotype (specimen ethanol preserved and dried). A, interradial superomarginal plates bordering paxillose abactinal area and fringed by protruding spinose extensions of inferomarginal plates; B, actinal plates bearing clavate (club-shaped) spines and finer spinules. The ambulacral groove with its furrow spines is aligned across the top right hand corner; C, X-ray negative radiograph of whole specimen; D, X-ray negative radiograph of arm base; inferomarginal plate extensions bearing the laterally projecting spines become narrower than the plates themselves, particularly interradially. Scale bars: A = 2 mm; B = 1 mm; C = 10 mm; D = 2 mm.
