By the foregoing general observations and explanations, it is trusted that the reader will be prepared for the following exposition of the general arrangement of Lamarck, and the principles upon which it is founded. GENERAL ARRANGEMENT ACCORDING TO LAMARCK. In Lamarck's " Histoire Naturelle des Animaux sans Ver- tebros," he divides the invertebrata into classes, the 9th, 10th, and 11th of which include animals possessed of shells properly so called. These are the Annelides, the Cirripedes, the Conchtfera, and the Mollusca.

This order includes tubular shells, which,.
