The /(('((</ is not rostrate, as loug as the first two pereional segments togetlier. The eijes are 

 small. The Hagelluni of the tirst pair of (inleiince is anteriorly obtuse, shortcr tlian the 

 head. The jiei-ciopoda are slender, not hirsute. The carpus of the first pair is dilated 

 but not priidiiced; the carpal process of the second pair is louger tliau half the metacarpus. 

 The tibia' of the third and fouitli pairs are not tuniid, the dactyli niiddle-sized. The fifth 

 and sixth pairs are scarcely longer tluin the third and fourth; the femora are biHiad, linear; 

 the dactyli are long. The dactylus ol' the seventh pair is a little shorter tlian the meta- 

 carpus. The jiereion is dorsally tubercidated. The second and tiiird ural segments are 

 coalesced. The hinder corners of the last segment are not produeed. The peduncles of 

 the iiropoda are a little longer than the rami, linear. The telson is middle-sized, triangulär 

 a little longer tlian half the pedunclc of the last pair of iiropoda. 



Coloui". Yellowish wiiite.

By the tuberciilou.s aspect of the pereioii this species is easily to be distinguished 

 from its allies. 



The Iwad is large, oiilv a little deeper thaii long. 



The eyes ave eomparatively small, elongated, a little broader a1jo\e. 



The first pair of antennce (Pl. VIII, tig. 10) are almost as long as the head and 

 the first pereional segment. The tirst joint of the peduncle is nearly twice as long as 

 the tAvo following joiiits together. The tirst joints <jf the fiagellum is a third longer than 

 the peduncle, the two terminal joints are verv lainiite. 



The second pair of antennas (Pl. \'I1I, lig. 11) are sliorter than the first pair, five- 

 jointed, the basal joint is the shortest. 



The pereional segments being separated from one another by deep impressions, 

 the pereion appears hiimpy or tuberculous. Between the tirst and second segments
