Figs. 6, 16) are more slender, the outer, widened part shorter than in flavescens,- but .small ones of the .same form as those oi flavescens (PI. XVII. F'ig. 9) also occur. The tridentate pedicellarise (PI. XVII. Figs. 5, 35, 39) have the edges of the l)lade more or less inrolled or even coalesced in the lower part, the outer jjart 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. P'S- 39) recall .somewhat the larger rostrate pedicellariie. The largest tridentate pedicellarise seen were only 0-3""" (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 oi 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 Danish Ingolf-Expedition (1895-1896); Københavns universitet.
