Descrição:	. The study of animal life. Zoology. CHAP. XV Backboneless Animals 239 The members of the last four classes usually breathe by means of air-tubes or tracheae, which penetrate into every part of the body, or in the case of spiders and scorpions, by " lung-books," which seem like concentrated and plaited tracheae. The King-crab (Limulus), which is very often ranked along with Arachnids, is aquatic, and breathes by peculiar "gill-books."

(From Fritz Muller.) time, and some shore-forms which live in great part above the tide- mark, the Crustaceans are aquatic animals, and usually breathe by gills. Each segment of the body usually bears a pair of append- ages, and each appendage is typically double. Among these ap- pendages much division of labour is often exhibited, some being sensory, others masticatory, others locomotor. In the higher forms the life-history is often long and circuitous, with a succession of larval stages. The lower Crustaceans are grouped together as Entomostraca. They are often small and simple in structure; the number of.
