thaii twice as long as all the following joints together. The tbllovving joirits 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 mäss of wartlike prominences, 

 exactly as in Vihilia robusta. 



The eirimerals are equal in depth, those of the lifth pair are the largest, those of 

 the seventh the smallest. 



The hranchial säcks are very large, as long as, or longer than the femoi'a of the 

 corresponding legs. 



The p/eon in tlie 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 posteriorl}' (Pl. XI, fig. 31), 

 in the last segment entirely smooth. 



The 2^leopoda (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 iiropoda (Pl. I, fig. 33 — 35) have the peduncles broad, linear. That of the first 

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

 coai'sely and complexely seri-ated, the large teeth being finely serrated ; the interiör ramus 

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

 than the exteriör 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 pi'eceding 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 leng-th of the peduncle of the last pair of uropoda.
