Dimensions in the preserved state. The largest breadth of the polyps was about 0-55 cm. The height was about 07 cm. excluding the groove-shaped ecenenchyme which may be of variable length (greatest length observed 14 cm.). The colour of living specimens has not been observed. In the preserved state the polyps are dirty coloured, lighter or darker. The polyps which are strongly incrusted witli foraminifera look as if they were covered with white grit. External appearance. The polyps are pear-shaped, in the proximal part often drawn out into a long narrow stalk, which often again increases a little in diameter towards the point and is sometimes somewhat swollen (see fig. 6 PI. 1 showing the most typical appearance of the polyps). This stalk which often had a groove-shaped appearance (fig. 15 — 16 PI. 2) does not however belong to the polyp itself but to the ecenenchyme. The cavity of the polyp namely is continued in the stalk part only as large canals, in contrast to what is found in I. arborescens. As the polyp, also in contrast to I. arborescens, is always unattached, this part which is strongly incrusted probably serves as a sort of anchor for the polyp. The groove-shaped part may possibly have surrounded some object, though the large material collected affords no evidence of this. The polyps are nearly alway
