“Je crois qu’on doit donner comme synonyme l’Anomia capensis Gmel., d’après la citation de Chemniz; mais l’individu que j’avais sous les yeux, n’est pas assez entier pour affirmer ce rapprochement.” There is obviously some want of farther explanation in these details, the omission of which may possibly be supplied by tracing the history of this interesting shell from the time in which it first appeared in this country; for there are local circumstances connected with it which having escaped the mention of Dr. Leach, and consequently of Lamarck, have led to the erroneous conclusion that it had remained till very lately undescribed. Dr. Leach was probably not aware, or through some oversight omits to notice that the specific name which he has given to this shell was that assigned to it many years ago by Dr. Solander, and that it has uniformly borne the name of _Anomia sanguinea_, or (_Terebratula sanguinea_) among all the English Naturalists in consequence from the time of that learned friend and companion of Sir Joseph Banks down to the present period: It is the Anomia sanguinea of Dr. Solanders MSS. and was designated under that name in the Museum of the Dutchess of Portland: it appeared under the same appellation in the catalogue of that museum, published in 1786: in the Calonnian Museum and Catalogue, printed in the year 1795; it stood under that name also in the Museum of Sir Ashton Lever, and it appeared under the same denomination in the sale catalogue of that museum, published in the year 1806. Under all these circumstances it may be presumed the name must have obtained no small publicity, and we need scarcely add that the example of these authorities were followed in the Cabinets of english collectors generally, that happened to be in possession of the shell, among which was that of Mr. Cracherode, which was subsequently deposited in the British Museum. And lastly, it should be mentioned that it occurs under the same name in the Testaceological Manual of Mr. Dillwyn. Nothing therefore can be more certain than that the french writers are not correct in their opinion when they imagine that the shell had been so named in the first instance by Dr. Leach; and it is no less certain that the credit of having first noticed the species is due to Dr. Solander, he described it more than forty years ago: his words as they stand in his manuscripts are, “ANOMIA SANGUINEA _obovato, longitudinaliter sulcata, triloba; sinu profundo nate producta latere angulata foramen ambiente_.” Mr. Dillwyn has well expressed the character of this shell in his description of Anomia Sanguinea, but has by some oversight misquoted this passage of Dr. Solander’s manuscripts; and by that means has confounded the _Anomia Sanguinea_ of Dr. Solander, with his Anomia Cruenta; this will be more fully shewn hereafter.
