The globiferous and ophicephalous pedi- cellariae (the latter rather numerous on the naked actinal part of the bivial ambulacra) are like those of flavescens. The rostrate (PI. XVII. Figs. 6,16) are more slender, the outer, widened part shorter than in flavescens; but small ones of the same form as those of flavescens (PI. XVII. Fig. 9) also occur. The tridentate pedicellarise (PI. XVII. Figs. 5, 35, 39) have the edges of the blade more or less inrolled or even coalesced in the lower part, the outer part being more spoon-shaped widened; in quite small specimens the valves are simply leafshaped (PI. XVII. Fig. 13). Some of the larger specimens (PI. XVII. Pig- 39) recall somewhat the larger rostrate pedicellarise. The largest tridentate pedicellarice seen were only o-3ram (length of head); doubtless larger ones will occur in larger specimens, and probably they will prove to differ yet more from those of flavescens. The triphyllous pedicellarise (PI. XVI. Fig. 12) differ from those of flavescens in being serrate almost all round the edge of the blade, only the point being smooth; the outline of the blade is also more rounded than in that Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Ingolf (Cruiser); Danish Ingolf-Expedition (1895-1896).
