Monhystera ambigua Bast., de Man. 1888, p. 7, pl. i, fig. 4. Monhystera vivipara Allg é n, 1929, p. 472, fig. 29 a-b. 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.
