much shorter than the femur of the sixth pair. The genu is longer than broad, a little 

 shorter than the tibia. The carpus is wider than the other joints, elongate-ovate, with 

 some few, short, equidistant bristles along the anterior margin. The metacarpus is much 

 shorter than the carpus, tapering, the hinder margin curved. The dactylus equals a 

 third of the length of the metacarpus; it is feebly curved, acute, of the same shape as 

 in the preceding four pairs. Glands as in the preceding pairs. 



The pleon is a little longer in the male, and the lateral parts reach farther down 

 than in the female; the lateral parts of the last two segments are deeper than those of 

 the first, they are all evenly rounded but shorter than the corresponding segment itself, 

 not occupying the foremost part of the segment. 



The pleopoda (PI. II, fig. 9) are larger and more developed in the male than in the 

 female, the peduncles being globular, and the rami containing some more articuli; in the 

 male the inner ramus has five, the outer seven articuli, in the female the inner shows 

 usually not more than three, the outer five articuli. 



The first segment of the urus is a little longer than the coalesced second and third, 

 and considerably more than half as long as the last pleonal segment. 



The uropoda (PI. II, fig. 10). The peduncle of the first pair is longer, but 

 not twice as long as the inner ramus, narrow, linear; the outer ramus is narrow, acute, 

 more than half as long as the inner, both margins smooth; the inner ramus is three times 

 longer than the breadth of the peduncle in the female, and about four times that in the male; 

 it is smooth along the inner convex margin, and strongly pectinated along the outer in 

 the male, but serrated on both margins in the female. The second pair hafve the peduncle 

 broader in the male than in the female; the outer ramus is more than half as long as the inner, 

 the outer margin smooth, the inner serrated; the inner ramus is much longer than half 

 the peduncle, elongate lanceolate, serrated on both margins. The third pair have the 

 peduncle as broad as that of the preceding pair, in the male; in the female it is a little 

 broader than the peduncle of the second pair; the peduncle is almost linear, more than 

 twice as long as the rami; the outer ramus, with the outer margin indistinctly serrated, 

 the inner serrated, is as long as the inner ramus, which is serrated on both margins, more 

 coarsely on the inner; the inner ramus is much longer than the breadth of the peduncle. 

 The uropoda are filled with glandular matter, the outlets of the glands are situated at 

 the bases of the rami just at their points of contact. 



The telson is broad, rounded behind, almost as broad as the peduncle of the last pair 

 of uropoda.
