than twice as long as all the following joints together. The following joints are sube- 

 qual in length, the dactylus a little the shortest, all richly provided with glands. The 

 dactylus is linear, rounded below and covered with a mass of wartlike prominences, 

 exactly as in Vibilia robusta. 



The epimerals are equal in depth, those of the fifth pair are the largest, those of 

 the seventh the smallest. 



The branchial sacks are very large, as long as, or longer than the femora of the 

 corresponding legs. 



The pleon in the male is almost as long as the whole pereion, in the female much 

 shorter. The segments are equal in length; the lower parts of the sides are evenly rounded, 

 in the first two segments showing a small serrated projection posteriorly (Pi. XI, fig. 31), 

 in the last segment entirely smooth. 



The pleopoda (PL I, fig. 32) have the peduncles shorter than the rami; the rami 

 are 13 — 14-jointed. 



The urus is as long as the last pleonal segment. The first segment is shorter than 

 the two following together; the second segment is much shorter than the third; the hinder 

 corners of the third segment are sharp-pointed. 



The (iropoda (PI. I, fig. 33 — 35) have the peduncles broad, linear. That of the first 

 pair is a little shorter than the exterior ramus (11:12); both rami are elongate lanceolate, 

 coarsely and complexely serrated, the large teeth being finely serrated; the interior ramus 

 is longer than the exterior (7:6). The peduncle of the second pair is a little longer 

 than the exterior ramus, linear; the rami are nearly equal in length, serrated in the same 

 manner as in the preceding pair. The peduncle of the last pair is a little narrower than 

 those of the preceding pairs, linear, twice as long as the rami; the rami are equal in 

 length, finely serrated. 



The telson is broadly rounded, half as long as the last ural segment and equalling 

 a fourth of the length of the peduncle of the last pair of uropoda.
