The fifth pair are the longest, and more slender than the two preceding pairs, but 

 with the same relative length of the joints. 



The sixth pair are shorter than the fifth, but similar in shape. 



The seventh pair (PI. VI, fig. 19) are shorter than the sixth, but as long as the 

 first pair. The femur is considerably broader than the following joints, more than twice 

 as long as broad, the margins are smooth. The genu is more long than broad, smooth. 

 The tibia is half as long as the carpus, smooth. The carpus is linear, much more than 

 half as long as the femur, the margins are smooth. The metacarpus is shorter than the 

 carpus, the hind margin is curved, the front margin straight, both are smooth. The 

 dactylus is curved, half as long as the metacarpus. 



The pleon is only a little longer than the dorsal margin of the last peraeonal seg- 

 ment; the first segment is the longest. The pleon and urus together are shorter than a 

 fifth of the diameter of the globe. 



The jyleopoda (PI. VI, fig. 20). The peduncles are longer than the rami, cylindrical. 

 The coupling spines and the cleft bristle are similar to those in Mimonectes Loveni. The 

 outer ramus has eight, the inner seven joints. 



The urus. The first segment is much longer than the coalesced second and third, 

 and a little broader. The last segment shows, as in the preceding species, a line of division 

 between the original second and third segments. The urus is scarcely longer than the 

 last pleonal segment. 



The uropoda (PI. VI, fig. 21). The peduncle of the first pair is almost four times 

 as long as broad, and about twice as long as that of the second pair; it is as broad 

 as the peduncle of the third pair, the margins are smooth. The inner ramus is narrowly 

 elongate, ten times as long as broad, a little broader than the outer ramus, the margins are 

 sharply serrated, almost pectinated, with long, narrow, spine-like teeth; the outer ramus is 

 only a little shorter than the peduncle, and more than half as long as the inner ramus, armed 

 in the same manner. The peduncle of the second pair is scarcely three times as long as 

 broad; linear, the margins are smooth. The inner ramus is more than twice as long as the 

 peduncle, narrowly lanceolate, more than ten times as long as broad, and a little broader 

 than the outer ramus; the outer ramus is much longer than the peduncle, and more than half 

 as long as the inner ramus; the outer margins of both rami are smooth, the inner margin 

 is armed as in the preceding pair. The peduncle of the third pair is longer than the last 

 ural segment, narrow, linear, fully thrice as long as broad, indistinctly serrated on the 

 inner margin, the outer one is smooth. The inner ramus is somewhat longer than the 

 peduncle, and a little broader than the outer ramus, both margins are pectinated as in 

 the preceding pairs; it is narrowly elongate, eight times as long as broad. The outer 

 ramus is as long as the peduncle, and a little shorter than the inner ramus; the outer 

 margin is smooth, the inner pectinated. Glands in all the pairs. 



The telson is nearly twice as long as broad, obtusely rounded behind, much longer 

 than the breadth of the peduncle of the last pair of uropoda, but shorter than half the 

 length of the peduncle.
