Tubercles in ambulacra II and IV first appear on plates 3a and b, and in I and V on plates 4a and b. By plates 5a and b, the size and spacing generally matches that of adjacent interambulacra. Largest tubercles with an approximate areole diameter of 1.0 mm occur on interambulacra 1 and 4 adjacent to adoral edge of plates 2a and b, aborally on plate 1, and along the adradial suture line between ambulacrum III and interambulacra 2 and 3 from the marginal fasciole to the apical disk. These tubercles have a perforate mamelon and crenulate platform but appear to lack a scrobular ring. Because of the very close spacing of these tubercles, miliary granules occur mainly towards the peristome and between the periproct and marginal fasciole in interambulacrum 5 where the spacing between the larger tubercles increases. They also occur around the apical disk.</paragraph>

A well-defined marginal fasciole occurs just above the sloping ambitus, dipping sharply below the periproct posteriorly but crossing ambulacrum III anteriorly slightly below the ambitus at about 25%TH (see fig. 2). The semipetalous fasciole is only marginally indented between the posterior paired petals and crosses interambulacra 1 and 4 on plates 8/9 before descending transversely to join the marginal fasciole at right angles, posterior to the angle of the anterior paired petals (see fig. 3I). Although continuous, fasciole widths vary but maintain a fine tubercule (granule) density of about 100–120 per mm

Anterior paired petals 138% longer than posterior pair, extending 50% of the radius (28.0%TL) measured along the surface of the perradial suture from centre of ocular to ambitus. Anterior paired petals diverge at 175° and contain 23/24 pore pairs, posterior petals 315° and 20/21 pairs. Outer pores elliptical, inner pores slightly smaller and more tear shaped. Zone between inner and outer pores approximately equal in width to outer pores, pairs not conjugate.Interporiferous zone marginally narrower than poriferous zones.</paragraph>

Adapically, the pore pairs are angled inwards at approximately 45° to the perradial suture but gradually become monoserial halfway towards the anterior ambitus. The ambulacrum is covered with closely spaced small tubercles and miliary granules, the former gradually increasing in diameter adorally.
