Behind this the nerves appear to vary considerably and run to the various muscles connected with the caudal furca. I have not followed them in detail. The ventral chain system consists of two parallel trunks which swell up in places and make various cross connexions. Liiders (1909, p. 138) states that there are four commissural connexions and these indicate that this chain system is primitive and represents the type of nervous system only found in the Crustacea among certain 6-2.
