The grooves appear to be exactly opposite each other (not alternate) and produce, on each side, a series of laterally di- rected, haU'moon-shaped leaflets. Superficially, as previously suggested, the appearance suggests a stack of coins with a cord running along it.

Superficially, as previously suggested, the appearance suggests a stack of coins with a cord running along it. Behind the clitellum the lateral grooving gradually disappears and the typhlosole becomes more nearly thickly laraelliform. The grooving is typical, characterizing each of the 77 worms of the 1956 series. The typhlosole ends in front of the 119th segment as shown in Table 3. Dorsal and ventral blood vessels have not been traceable an- terior to 5/6, probably because they are empty. Extra-oesopha- geals, median to the hearts and in contact with the gut only in.
