It includes the crabs ami lobsters, spiders, centipedes, Insects, etc. All these creatures afirec in having the body built in >e^- nienl?- or rings, all or some of which bear jointed append- iii^es. The Insects ditfer from the others in hnving these segments grouped, in adult life, into three regitjns, usuallv <piite distinct. These regions are the head, the tor('-bod\", and the hind-body. The spicUrs. which are conimonh- regarded in popular esti- mation as Insects, lia\'e onlv two bod\-regions. There arc other differences, of course, which are not e\ident u])on a superhcial view of the exterior form ; but e\en hero two or three additional points may be mentioned, contrasting a spider witii an Insect. The head of the Insect bears a pair of an- tenn;e. or " feelers" ; the spider lias no antennit. The Insect, with a few excep- tions among the sim])ler forms, has a pair of prominent compound eyes made \ip of a large num- ber of lenses, and two or three simple eyes, or " ; placed between the compound eyes. The spider's eyes are all simple, and number.
