The appendage, especially when long, is apt to be wound towards its extremity into a spiral, and its last four joints usually possess a peculiar armature. In Bhynchothorax this ^'°- ^72. ~ Nymphon takes the form of a stout toothed tubercle. Terminal joints of ovigerous leg, with magnified "; on each joint ; in Colossendeis of several rows of small imbricated denticles; in Nymplion and Pallene of a single row of curious serrate and pointed spines, each set in a little membranous socket.
