FIGURE 3 in Two new species and a new subspecies of Tetraclitella (Cirripedia: Thoracica) from the Cainozoic of Australia and New Zealand and a consideration of the significance of tubiferous walls

FIGURE 3. Tetraclitella judiciae sp. nov. P313914 (holotype)–shell with opercular valves absent (the opercular opening is the large central quadrangular structure); carina at top. The dark, "round" cavity (c. 1.0 mm in diameter) to right of the opercular opening is an eroded radius, and it is here where the recrystallized shell fabric is suggestive of having had radial pores.
