Lambis cheragra
1. Cypraea lutea Gronovius, 1781 Zooph. Gron., pt. 3, p. V, pl. 19, fig. 17 C. lutea Gmelin, 1791 (Linn. Syst. Nat., ed. 13, 1:3414, no. 78) should replace it, as Gmelin was the first to validate it.
2. Cypraea corrosa Gronovius, 1781 Zooph. Gron.; pt. 3, p. V, pl. 18, fig. 10 The name corrosa had been used in a subspecific sense by the Schilders and other writers for the race of C. caurica Linné,
1758, from India, Ceylon and West Malaysia. The name should be replaced by C. caurica derosa Gmelin, 1791 (Linn. Syst. Nat.,
ed. 13, p. 3416), which has usually been regarded as a synonym to corrosa.
3. Amphiperas Meuschen, 1781 - Index to Zoophl. Gron., p. 293 The genus had Bulla ovum Linné, 1758, as type species; it should be replaced by the well-known Ovula Bruguière, 1789 (Enc.
Méth. Vers., 1:15).
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 Naturæ (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.
