Note 34 — Class—CRUSTACEA. Sub-Class—CIRRIPEDIA. (continued 3)

The general title to the volume, containing four Quarterly parts, is dated 1818; but as in the ‘Journal de Physique,’ for July, 1817, the editor refers to Conchoderma, the Quarterly Part containing this genus must have appeared before 1818: Lamarck gives the year 1814 as the date of the paper in question, and I have accordingly followed him. From a similar reference by the editor, it appears that Schumacher’s volume appeared before the number of the ‘Journal de Physique’ containing Leach’s Paper.
