The greater number of the Crustacea here figured have been described by Mr. Adam White. The plates having been printed off many years since, and the stones destroyed, it has not been possible to alter their lettering, and bring it into correspondence with the nomenclature adopted in the text; but whenever I have adopted for any species a different generic or specific name from that used by Mr. White, and printed on the plate, a reference has been made to the latter in the synonyma of the species.
