Note 444 — Chapter XIII

Foss. South D. tab. xxx. fig. 3. In the beautiful work of the late Mr. Dixon, on the Fossils of Sussex, there are figures of very fine specimens of these two species of Enoploclytia (plate xxxviii*.) with detailed descriptions by Prof. Bell (p. 344); but unfortunately, from inadvertence, no reference is made to my former drawings and descriptions of these fossil Lobsters of the Chalk, and new names are given by the Professor; E. Leachii appearing as "Palæastacus macrodactylus," and E. Sussexiensis as "P. Dixoni." I need scarcely remind my readers that according to the established rules of Nomenclature the earlier specific names must be preserved; and that, Prof. M‘Coy having already indicated the distinction of these fossils from the recent Astacus by providing an appropriate generic appellation, these new names are altogether inadmissible.
