Note 63 — Class—CRUSTACEA. Sub-Class—CIRRIPEDIA. (continued 6)

This is one of the rare cases in which, after much deliberation, and with the advice of several distinguished naturalists, I have departed from the Rules of the British Association; for it will be seen that Mitella of Oken, and Ramphidiona of Schumacher, are both prior to Pollicipes of Leach; yet, as the latter name has been universally adopted throughout Europe and North America, and has been extensively used in geological works, it appears to me to be as useless as hopeless to attempt any change. It may be observed that the genus Pollicipes was originally proposed by Sir John Hill (‘History of Animals,’ vol. iii, p. 170), in 1752, but as this was before the discovery of the binomial system, by the Rules it is absolutely excluded as of any authority. In my opinion, under all these circumstances, it would be mere pedantry to go back to Oken’s ‘Lehrbuch der Naturgeschichte’ for the name Mitella,—a work little known, and displaying entire ignorance regarding the Cirripedia.
