Head continuous with the neck contour, neither lips nor papillae elevated;
amphid aperture about one-fourth as wide as the lip region, expanding inwardly
until half as wide as the head; tails of both sexes elongate-hemispherical;
posterior two-fifths of esophagus enlarged until two-thirds the body width;
spear slightly longer than head width, the aperture occupying two-fifths
its length.
General description: Cardia cylindroid,
one-third the neck width; intestine two-thirds the body width, four to
six cells in circumference; prerectum and rectum each somewhat longer than
corresponding body diameter; ovaries reflexed nearly half-way to vulva.
Spicula slightly arcuate, nearly twice as long a anal body diameter; probably
inconspicuous supplements and submedian papillae present but none were

made by Dr. Cobb in 1910 and preserved in balsam.
