Cyprea vitilus
The animal: The riving animal observed by Mrs. Couacaud, was as follows: The sole of the foot reddish-orange, dorsum of foot
bright red. Mantle bright red, with minute black spots, giving it a darker appearance; on close observation it could be seen,
that the black spots were set out in small circles around the papillae, recalling somewhat the design of the shell. The
majority of papillae were bright red a few (about 8) were whitish, and surrounded with minute white specks at the base;
papillae were short and simple, not exceeding 1 mm in length. Siphon red, tentacles bright red and pointed.
The description of the animal of C. esontropia, agrees almost in detail with that of C. cribraria from Fiji (see The Veliger,
1964, 6(4):199).
C. cribraria is not known to occur in Mauritius; Viader (Maurit. Inst. Bull., 1(2), 1937), recorded C. cribraria from
Mauritius, however, Viader's records are unreliable, and were compiled from literature records and not actual specimens
examined. Viader reports Pacific species, e.g. C. eburnea, C. mariae and C. gaskoini from Mauritius.
C. esontropia most probably evolved from C. cribraria, through effective geographical isolation, on the same lines as C.
caputdraconis from Easter Island (Pacific), C. semiplota Mighels and C. granulata Pease, from Philippines, and C.
erythraeensis Sowerby, from the Red Sea region. C. esontropia is regarded as a weak species by some, strong subspecies by
others, and a valid species by most workers.
