hinder margins of all the segments are bisinuated. The upper 

 side of each segment is transversally convex at the hinder 

 margin. The incuhatory youcli (Pl. V fig. 48) consists of four 

 large, deeply engraved lamina, and one smaller one anteriorly 

 on each side. 



The epimerals (Pl. V. fig. 48) are subequai in length. 

 Those of the second and third segments are oblong, straight, 

 the first mentioned is rounded at both ends, the latter 

 pointed at the anterior and emarginated at the posterior end. 

 The >epimerals of the following segments are concavated at 

 the inferior margins. None of the epimerals occupy the whole 

 length of the lower side of the corresponding segment; that 

 of the sec(md segment occupies three fourths, that of the fourth 

 segment only half of the segment. 



The first three pairs of pereiopoda have very long femora 

 and short dactyli (Pl. V fig. 53). The fourth pair are the 

 smallest of all the legs (Pl. V fig. 54). The fourth to seventh 

 pairs have broad femora and long strong dactyli. The seventh 

 pair (Pl. V fig. 55) are the longest and strongest of all, with 

 the femora almost as broad as long (20 : 21). 



The pleon is only feebly immersed, the lateral corners of 

 the first segment are not covered but free ; the pleon is broader 

 at the base than long (3 : 5). The first segment is broader 

 than half of the fifth segment (2 : 3). The first four segments 

 are equal in length, the fifth a little longer (5: 3). The corners 

 of the segments are narrowly rounded, free from one another. 

 The pleon is a little longer than the first pereional segment. 

 (15: 14). 



The itrus is broader than the last pereional segment, 

 slightly emarginated at the anterior margin, the posterior 

 maroin being- straight with rounded corners. The urus is 

 longer than the pleon (17 : 15) and much broader than the 

 last pleonal segment (4 ; 3), more than twice as broad as long 

 (39 : 17). Its upper side is smooth without impressions. The 

 pleon and urus together are a little longer than a third of the 

 pereion with the head (16 : 45). 



The uropoda (Pl. V fig. 56) do not by far reach to the 

 posterior margin of the urus. The rami are ovate lanceolate, 

 the inner one shorter than the outer. The peduncle is stout, 

 longer than the inner ramus.
