One pair commissural blood vessels connects dorsal and ventral blood vessels in posterior part of anterior segments to about XX or XXI; these vessels lack a dense chloragogen layer; in pre-clitellar segments they are long and sinuous, joining the ventral vessel in the next segment. One pair lateral, blind blood vessels joins dorsal vessel in anterior part of segments beginning about XV to XXII; short and unbranched at first, but by XXV reaching ventral part of the body, with few branches; these vessels thick and covered with chloragogen.
