Only six primary pairs of 48 total pairs mesen teries complete; mesenteries widest proximally; those of highest order may extend only to distal end of scapus; regularly arrayed; thin but tough, all with filaments (which may be reddish brown). All except primary mes enteries fertile; dioecious; ova may exceed 1 mm diameter in preserved specimens. Two sym metrical directive pairs attached to siphonoglyphs; actinopharynx as much as two-thirds total column length but in some only siphonoglyphs extend so low, deeply to hardly sulcate (perhaps dependent on state of expansion of entire animal).
Wall of well-preserved specimens raw umber to rust brown color, rugose, leathery, commonly with circumferen tial folds; ectoderm of poorly preserved specimens friable, eroded in places, dark brown to black. Uppermost column smooth, collar-like; fosse deep. Base. Flat; edge of most specimens con tracted so diameter considerably less than that of column (Figure 29b) although in some it is slightly flared; same color as column. Tentacles and oral disc. Oral disc equal to or wider than column, edge wavy in large specimens; cannot be retracted much.
