Diameter of disk apparently not surpassing ca. 5 mm.; arms short, not more than four to five times the diameter of disk. Circumference of disk round. Dorsal side of disk with rather large, irregular scales, the largest at the centre; primary plates not distinct. Radial shields short, rather broad, widely diverging, sometimes contiguous distally. Ventral interradii wholly covered with rather large scales; the proximal part of the interradii in the adult usually more or less swollen (on account of. Fig. 13. Amphiura monorima, Part of oral side (a) and dorsal side (/)). â : 20, the sexual products). Buccal shields with a rather sharp inner angle and a broad truncated outer lobe. Adoral plates joining within, generally broadly so. Outer mouth papilla rounded, very small, sometimes totally wanting, infradental papillae rather pointed, well developed. The pore of the outer mouth tentacle continues inwards in a furrow, produced by the scale of the inner mouth tentacle being somewhat raised. As the jaws are somewhat sunken the part of the mouth frame proximally to the adoral shields is rather conspicuously sunken; round this sunken part the adoral shields, together with the buccal shields and the first ventral plate, form a somewhat raised pentagon, the corners of which are occupied by the buccal shields. The sides of the pentagon are slightly concav
