  The ovate, red-coloured central capsule exhibits in the
      lower half the striate podoconus, in the upper half
      four oil-globules, and at the left the kidney-shaped
      nucleus. Numerous "yellow cells" or xanthellæ are
      scattered in the calymma, which contains brown pigment
      around the porochora. Numerous pseudopodia radiate from
      the supporting spines of the sagittal ring.
