Ventral blood vessel divides in VII; the two branches join anteriorly in front of the brain at the dorsal vessel. One pair lateral blood vessels in posterior part of each segment; they are unbranched and convoluted in XII and anterior, and branched in posterior segments. Anteriorly to about XXXV lateral vessels (or a main branch) terminate in the ventral vessel. In more posterior segments (to at least XLV) a thick branch joins the perivisceral sinus, and a thin branch joins the ventral vessel. Nephridia paired, occurring regularly in most segments posterior to XII. A small, bulbous postseptal expansion is followed by a tubule loop that follows commissural blood vessel to near the dorsal vessel (
