Rare variations of these may be 3-6-armed with one or more arms branched at tips, length of stem mm, length of arms mm. Curved spinous rods scarce, mm in length. Spinous 4-armed crosses with 2-4 apophyses (Fig. 9B) not common; length of stem mm, apophysis

There may also be present smooth crosses with 1-4 apophyses, often much longer than the arms of the rods; when single apophysis present, this is densely setose (Fig. 9C). In addition, there are numerous other smooth crosses, with up to mm long arms, and rods up to 2 mm in length, of possibly foreign (?sponge) Fig. 10.
