. a b Fig. 10. Amphiura grandisquama, var. guineensis, Part of oral side (a) and dorsal side (b). X24. typical A. grandisquama in having much finer disk scales, in having often six arm spines on the proximal joints, and in the outer mouth papilla being in general more rounded, scale-like. Also the ventral arm plates are somewhat different from those of typical grandisquama (compare fig. 10 with fig. 19 of my Echinoderms of St Helena). Further, the interradii bulge conspicuously outwards between the arms. The spines show more or less distinct traces of brownish colour in their basal part
