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 100120 per mm

The ambulacrum is covered with closely spaced small tubercles and miliary granules, the former gradually increasing in diameter adorally.
