| Within the septate group there are uniserial and coiled forms. |
| Secundibrachials slightly cuneate uniserial, same approximate dimensions and same distal expansion as on primibrachials, aborally rounded. |
| One isolated uniserial arm trunk with biserial ramules was recovered from the Nada. |
| Scutum dark grey with slightly brownish dusting, 2 stripes faintly visible, pleura grey dusted, dorsocentrals uniserial. |
| Taxa within the group are variously unilocular or multilocular, spherical, tubular or uniserial, and coiled or uncoiled. |
| Uniserial budding produces a chain one zooid wide, whereas, colonies that are biserial, zooids share one wall and result in a strip two zooids wide. |
