Archive image from page 58 of The Danish Ingolf-Expedition (1907). The Danish Ingolf-Expedition danishingolfexpe0402ingo Year: 1907 B( HINOIDEA. II. -j ferous pedicellarise (PI. X. , ul are very characteristic, the valves ending in a single long tooth, at a right angle with the narrow blade, which forms a flattened, closed tube. As in Urechinus the valves are clad with a thick, dark, evidently glandular skin. Xoneek; the stalk is more compact than in Urechinus. In the two globiferons pedicellaria: I have seen, the valves are nnsvmmetrieally devel- oped in the basal part, the one figured from the inside being the most regular of them. Whether this is a constant feature it is, of course, impossible to decide from such scanty material. The ophieephalous pedicellariae (PL X. Fig. 26) have low and broad valves, somewhat sinuate and very finch- and closely serrate along the edge of the blade down to the apophysis. The upper end of the stalk as usual cupshaped. The tridentate pedicellariae occur in two distinct forms; the one (PL X. Fig. 22) has very long and narrow valves, somewhat widened in about the outer third, where the valves join. The edge of this widened part is closely serrate; in the lower, narrowed part the edge has only some very few small thorns. The blade is open along the whole length; there may be a faint indication of a meshwork in the blade. This form reaches a length of ca. r2mm (head). The other form (PI. X. Fig. 8) has the blade almost, sometimes completely, closed as a tube in the lower half; the outer half is spoonshaped widened, with the edges finely serrate. In smaller specimens the narrowed part of the blade is shorter, in cjuite small ones it is not narrowed at all, the blade being simply leaf-shaped. This form is much smaller than the former, the largest ones seen being ca. o-5''n. The triphyllous pedicellarise (PI. X. Fig. 14) are like those of I 'rich, giganteus, only somewhat more narrowed below the blade. — The spicules and the rod
