); the prosegment bears a hydrotheca, its complement of nematothecae, and a pair of opposite cladial apophyses; the remainder of axis comprises a succession of hydrothecate internodes, each bearing a cladial apophysis lateral to a hydrotheca (proximalmost hydrotheca occasionally has a pair of opposite cladial apophyses); the apophyses are arranged alternately along the axis. With the exception of a short, proximal, athecate internode, followed by a nematothecate internode, the remainder of cladium is composed of a succession of thecate internodes separated by oblique nodes. Each hydrotheca, on both axes and cladia, is surrounded by 5 nematothecae: a mesial (well below its basis), a pair of laterals (of varied length and borne on short, conical apophyses), and a pair of axillar (
