COPEPODA

the ventral protuberance is in lateral view scarcely different from R. Farrani ; the anterior process is 

 comparatively shorter, but the posterior margin and the dorsal lateral process are scarcely different. 

 In the transverse chitinous plate no median incision was found posteriorly; covered by this plate a 

 chitinous system was found with a median incision (text-figs 49 a — d).

The measurements of the antennulae show in the examined specimens a slight difference from 

 R. Farrani; the segments 240^25 are slightly longer than, (not=) segment 19 and the segment 21 is 

 almost n as long as 17 (not as long as). The lye of the maxillulae possesses in the examined specimens, 

 in addition to the usual 5 long setae, 2 shorter ones, showing from fairly long to very short variations.
