The endopodite has on its posterior surface 3 + 2 spines; the exopodite has 5 spines at the base of Se Re I, 6 spines at the base of Si Re II, and near the inner margin of Re III three groups consisting of 4, 3 and 3 spines. The endopodite of the second pair of legs has a long pointed Se in the Re I; on the posterior surface of Ri I a group of 5 fairly strong spines is found, and in Ri II two outer rows of 6 spines and an

The endopodite of the second pair of legs has a long pointed Se in the Re I; on the posterior surface of Ri I a group of 5 fairly strong spines is found, and in Ri II two outer rows of 6 spines and an inner one of 8 weaker spines. The terminal seta, which is like that of the preceding species, is as long as the third outer segment; on the posterior surface of the third basipodite and the exopodite groups of rather short spines are found; the number of glandular pores is like that of O. magmis. The armature of the posterior surface of the third pair of legs is like that of the preceding species; the endopodite has 5 long spines in Ri I, a curved row of 7 long spines and an inner group of about 20 setae in Ri II, and in Ri III groups of 5 strong and 12 short spines; the exopodite has a number of short spines and bristles. The third outer segment is, as shown in text-fig. 73 b, curiously short, probably due to ac- cident; a similar abnormal structure has been described by Wolf en den in the fourth pair of legs of the male of C. chelifer (1911 p. 283). The fourth pair of legs has the armature somewhat less developed, but the third outer segment was trans- formed in a similar way. The terminal segments of the third and fourth pairs of legs were only examined on the left side, as they were wanting on the right side. The fifth pair of legs (text-figs 74 câe) con- sists of three segments, which are almost com- pletely smooth on the anterior surface, but post- eriorly at least in distal half of the segments, they are covered with fairly long stiff hairs; the left leg has terminally
