These principal groupsare subdivided into seven secondary groups, sections or p],,. f^^^^y ^.^ijeg comprising the Sedentary spiders are named .strictly ^ from the cliief characteristics of their spinningwork, viz.: the Orbi- Group. Lb telarite, from their orb shaped web; the Retitelaria, from theirnet like web or snare of crossed lines; the Tubitelarise, from the tubularweb which they spin, and from the opening of which, in some species, a close textured snare spreads out in. all directions; the Territelaritc, fromthe silken cylinder with which thetypical species line their burrowsin the ground. The Wandering spiders includethree tribes, which are conspicuousby their ordinary independence ofsnares for the capture of prey, andhave been named from certain pe-culiarities of motion. TheLaterigradse have legs so Wander-ing Group inserted as to permit amotion sidewise, as well as forwardor backward. For this reason La-treille called them also Crab Citigradffi include those speciesthat keep cliiefly to the land andwater, upon which they run withgreat rai>idity. The Saltigradtt, orvaulting spiders, are named fromtheir hopping movement in ordi-nary progress. The individuals ofthese three tribes are ec^ual-ly entitled to be called citigrades,for they all move swiftly, but theCitigrades
