Disarticulated valves, dorsal surface. Length of live animal 16mm.
Outer coloured layer of shell (tegmentum).
Properiostracum (outermost proteinaceous layer) thin on this species as unobtrusive and no appreciable immediate loss of dorsal colour after boiling.
At right, head valve i enlarged and tilted to expose steep sloping face; granules follow indistinct semicircular growth lines.
White apophyses on valves iv-viii are short (i.e. antero-posterior distance), wide, near-trapezoidal, some with gently curving anterior edge, but those on valves ii & iii are more strongly curved.
(Tail valve viii deformed on this specimen.)
