Basipodite with a large blade and 3 small bristles. 
Endopodite with 2 lobes, the inner lobe with 4 bristles and a small 
masticatory process, the outer lobe with 6 bristles.

Stace V (Plate 1, Fig. 5). This specimen, the only one of its kind 
found, was unfortunately dead and damaged. Length of body 0-51 mm. 
Much like Stage IV. The hind part of the body divided into 2 segments 
with indications of a third, and besides Appendage IV there are traces 
of V and VI, which show as minute knobs. The armature of the hind 
end was damaged, but 3 pairs of lateral hooks could be seen, so that 
there are almost certainly 2 end feelers, a pair of end hooks and 2 pairs 
of ventral hooks, corresponding to the same stage in Pseudocalanus. 
Appendage I. ANTENNULE (Plate 2, Fig. 5) with 3 segments, the Ist 
with no bristle, 2 imperfectly divided into 3 each. with a bristle, the 
terminal segment with one proximal and 2 distal bristles on the ventral

long bristles and an accessory bristle at the end. A row of minute hooks 
occur inside the tip of the terminal segment.
