The coral is cuneiform and very much compressed at the base, which is rounded inferiorly. The calice is elliptical and shallow. The septa are delicate ; the principal are exsert and rounded, having large lateral spiny granules. There are six systems of septa, and four cycles. The first three orders are nearly equal ; but the septa of the fourth and fifth orders are small, curve towards and touch the tertiary. The pali are tall rounded lobes on the tertiary septa ; they are stout, larger than the end of the septa, and are sparsely granular. The columella is long and papillary. The costae are visible to the base, are slightly wavy in their course, are separated by di-
