Remarks
This is the first record of this species from southern Africa, south of the tropic of Capricorn. Its Querimba (northern
Mozambique
) record is that of
Pearson (1910)
. The
two specimens
at hand measure 114 x
81 mm
and 102 x
32 mm
; both are chocolate brown dorsally, paler ventrally, with a much paler patch around the anus. The podia are all retracted, scattered in the larger specimen but with some indication of their arrangement in rows ventrally in the smaller specimen. There are 18 tentacles with the mouth and anus both subventral. The stone canal is suspended in the dorsal mesentery, the Polian vesicle terminally saccular and the madreporic body spherical. There are no Cuvierian tubules. The spicules of the dorsal body wall (
Figure 4A
) measure
17–41 µm
and those of the ventral body wall (
Figure 4B
)
19–28 µm
. The rods of the podia (
Figure 4C
) are
51–110 µm
long; those of the tentacles (
Figure 4D
)
97–218 µm
. This species is well characterised by the pale patch around the anus and the presence of only minute, poorly branched rods in the body wall.
