Globiferous, rostrate, tridentate and triphyllous pedicellarise have been found; ophicephalons ones do not seem to occnr. The globiferous pedicellarise (PI. XVII. Figs. 37, 49) are very conspicuous, with a thick, brownish head; the valves are very short, with a very large basal part and a short, tubeshaped blade, which has 5—6 teeth along each side of the elongate terminal opening and often an outer median one.

The stalk has a whorl of free projecting rods at its lower end; the upper end is attenuated. These pedi- cellarise I have found only on the actinal side, and only in specimens from the Mediterranean, never in any specimen from the northern seas. In some specimens from Tamaris (Var), which Professor Koehler has most kindly lent me for examination I find them thus represented: in one specimen (the largest) they are very numerous and well developed; in four specimens there are very few of them, at the mouth or on the anal area, and they are small, the basal part being not very large and the whorl on the stalk little developed; in two specimens I find no globiferous pedicellarise at all —.
