The pleon is considerably shorter than the pereeon, equalling in length the last 

 four peraeonal segments together; the first pleonal segment is shorter than the last two 

 pergonal segments together. The lateral parts of the segments are not fully as largety 

 developed as in the male, but of the same shape. 



The pleopoda are like those in the male. 



The urus. The first segment is longer than the last coalesced one. The whole urus 

 is longer than the last pleonal segment. 



The first pair of uropoda (PI. VII, fig. 26) do not reach fully to the apex of the last 

 pair; the peduncle is four times as long as broad, longer than the inner ramus; the outer 

 ramus is almost as long as the inner one, smooth on the outer margin, and serrated along 

 the inner one; the inner ramus is serrated along both margins; at the bases of the rami there 

 are deep grooves or holes, as described in the male. The second pair have the peduncle 

 three times as long as broad, only a little longer than the inner ramus; the outer ramus 

 is shorter and narrower than the inner, smooth on the outer margin, and serrated along 

 the inner one; the inner ramus is serrated along both margins. The third pair are less broad 

 and stout than in the male; the peduncle is three times as long as broad; the inner 

 ramus is much longer than the breadth of the peduncle, serrated along both margins; 

 the outer ramus is rather longer than the inner one, and a little narrower, it is smooth 

 on the outer margin and serrated along the inner one. 



The telson is broadly rounded, equalling a third of the length of the peduncle of 

 the last pair of uropoda, it is fully as long as the breadth of the peduncle.

The head equals in length the first two peraeonal segments together. The tibial process of 

 the first pair of r pera>opoda does not reach to the base of the carpal process; the front margin 

 of the carpal process is serrated, a little shorter than the hind margin of the metacarpus. 

 The dactylus of the second pair is retractile, able to be drawn in into the apex of the meta- 

 carpus. The carpus of the third and fourth pairs is a little dilated, the hind margin 

 serrated. The last three pairs are not longer than the two preceding pah's(?); the femur
