    • chilognatha An order of the class Myriapoda; the myriapods or millepeds proper, or thousand-legs. They have a cylindric or subcylindric segmented body with a hard crustaceous integument, and 2 pairs of legs to each segment or somite (excepting certain anterior ones); no footjaws; and a 4-lobed plate behind the mandibles, which are without palpi. The antennæ rarely have more than 7 joints. The genital openings are on the coxal joint of the second pair of legs. They are sluggish animals, living on decomposing animal and vegetable matters, and depositing their eggs in the ground. They have the appearance of hard round worms with numberless legs, and some can roll themselves up in a ball, circle, or spiral, like some of the wood-lice. There are several families, with numerous genera and species. Diplopoda is a synonymous term. The term is contrasted with Chilopoda. Also written Cheilognatha. See cut under milleped.
