Dimensions.--Body-length= 0.711 mm., max. width= 0.026 mm., oesophagus=0.0 7 0 mm., t a i l=0.8 0 mm., α=2 7.3 5, β=10.16, γ=8.8 9.

In my material also a very faded female and an adult specimen o f a Monhysterid were recorded, which in the shape of the h e a d (buccal cavity, lateral organs) a n d the tail seem t o agree r a the r well w i t h this marine saprophagous species.

The cuticle is smooth and the head is rounded, provided with very short, submedian bristles.

Buccal c a v i t y small, funnel-shaped. Lateral organs situated 15/z behind the front end, probably rounded.

(Esophagus short, posteriorly gradually thickened.

The elongated, pyrifbrm, granulated ventral gland is situated only a short distance behind the (esophagus and is provided with a central nucleus.

The tail is short, conical and contains in the anterior half three large glands with central nuclei. I t is provided with a short, conical end tip. Egg cells large.
