The year 1758 marked the beginning of a whole new era of systematic enlightenment. Linnaeus introduced for the first time an
orderly arrangement for the animal kingdom, among them the mollusca in general and the Cypraea in particular. He enunciated
the first acceptable principles for defining species and genera, and this, with his suggestion for a simple binomial
nomenclature, resulted in the first systematic arrangement to enable workers to sort their material in a logical manner.
Linnaeus' famous work, Systema Naturę (10th edition) first fixed the taxonomy of the Cypraeidae in a way that made sense; the
International Commission on Zoological Nomenclature uses this work as the starting point for name priority in all animal
groups.
With this starting point in mind, subsequent work on the Cypraea can be traced through the literature in fairly definite
stages: the first stage is evidently the study of local populations; the second, the acceptance of possible environmental
influences, and the third would be the study of species and races in a broader sense. These are the essential stages to be
considered in the study of any shell family group.
After Linnaeus, many other naturalists contributed their work to subsequent volumes. Gmelin 1789-1791 is the author of the
13th Edition of Linnaeus' earlier work; he revised it by adding many new species and enlarging the bibliographic references.
Gmelin mentioned a total of 114 species of Cypraea.
Just inshore of Barber's Point lighted buoy is a more or less flat coral plateau. This area is best remembered, as far as my
diving is concerned, for two things. Most important, because it concerns shells, is that I collected six live and two dead
specimens of Murex insularum in a half hour dive on this coral plain. The second item is that the largest shark I ever
encountered in Philippines waters came face-to-face with me as I came up onto the top of the cliff from the deeper water
offshore. He seemed to be hovering there, perhaps measuring me for size. Other than the M. insularum this area offers little
in the way of collecting. It is basically barren, free of any coral heads or rubble. Simply a flat, hard ocean bottom.
