Srnt'ujem coleojrtnitti, L., South < in-many and Italy. Order '2.—CHILOGNATHA. The shape of the body is cylindrical or subcylindrwal. There is a four-lobed plate behind the mandibles, and two pairs of legs on each segment (the anterior segments excepted). The genital openings are on the coxal joint of the second pair of legs. The body of the Chilognatha is, as a rule, cylindrical or sub- cylindrical. The segments have the form of complete rings, or are provided with special dorsal plates. In many cases (Julid(e) the body is much elongated ; in others (Glomeris) it is short, like that of a wood-louse (tig. 427). The antenna? are short, and consist only of seven joints, of which the last may abort. The mandibles are provided with broad masticating i, Maxillae surfaces, which serve to crush the vegetable matters on which the animals feed, and with an upper movably articulated pointed tooth. The maxilla? are united so as to form an inferior buccal plate, the sides of which bear two rudimentary hook-shaped blades (tig. 427, b), while the middle portion appears to represent the underlip. The eyes, which as a rule consist of aggregated simple eyes, are situated above and external to the antenna?. The anterior thoracic legs are as a rule directed forwards towards the mouth. The three thoracic segments, and sometimes the next two or three segments, bear a single pair of legs. All the others, except the seventh in the male, bear two pairs. Stigmata are present in all the segments, and are more or less hidden beneath the coxal joints of the limbs. The rows of pores (foramina repugnatoria) on either side of the back, which are often ta
