It seems as if Strombus hawaiensis may not be as rare as once believed, but it will always be a difficult shell to find. They
bury quite deeply in the sand without any track or trace. The depths at which they are found inject a definite hazard into
diving for them. Such vigorous fanning is required as to place a diver in jeopardy by obscuring himself in a cloud of
sediment. Not [just] any deep coral bottom covered with sand could be considered likely territory for the shells for there
must be a generous supply of filamentous algae for feeding. A second true plant (one having a root system) is also found at
this site and may have some bearing on the matter. Even sand density, depth and granular quality may be important. It appears
quite definitely that the amount and type of rubble present with the sand is an important factor. The shells displayed a
decided tendency to avoid larger rocks while in the aquarium. Much of this mystery remains unsolved making pure luck a
significant constant in the discovery of this beautiful shell.
Judging from beach results I think the following areas may prove profitable for future exploration:
Haga-Haga, Cypraea capensis; Kei Mouth, Epitonium coronatum; Bashee Mouth (to right of Hotel), Cypraea marginalis, Cypraea
carneola, Cypraea chinensis; Coffee Bay, Cypraea vitellus, Cypraea helvola; Xora Mouth, this locality has species also found
on east and south coast including Voluta africana, Cypraea citrina, vitellus, helvola, arabica, moneta, and Tonna variegata.
I think this should prove the most profitable during the winter months of July and August.
In Sean Raynon Sabado (n.s.) 72:8 (1965), Dr. R. Tucker Abbott tried to prove that the specific name Cypraea arenosa Gray
(1824) is not preoccupied by Cypraea arenosa Dillwyn (1823) and therefore should be restored. His deductions, however, are
erroneous and caused further confusion among collectors.
First, Dillwyn did not say that arenosa is a synonym of pantherina as suggested by Dr. Abbott, for Dillwyn's explanation to
Lister's figure 685.32 runs as follows: "Quoted by Dr. Solander in his Ms. for his Cypraea arenosa; and it is probably a
young shell of Cypraea pantherina." Therefore he adopted Solander's name in the same way, as he quoted, on the same page, the
published Cypraea nebulosa of Gmelin and C. cervus of Linnaeus as varieties of stercoraria and C. exanthema respectively. In
1827, Dillwyn treated "Cypraea arenosa of Solander" as a synonym of C. turdus.
