Lip
region set off by a deep constriction, slightly more than one-third
as wide as base of neck. Spear

extension. Esophagus enlarged slightly anterior to middle.
Intestinal cells with brown granules. Female prerectum length one
and one-half times anal body diameter. Anterior ovary extending almost
to base of esophagus, the posterior reaching half way to anus. Supplements
15, slightly separated, the series beginning about half a body width anterior
to the spicula.
Male prerectum extending to a point about midway of the supplements.
