Iinii-s, serrated upon one Hide nud curved at the npcx. First ]»air 

 of maxillie havnnf; tho ischium lonii; and the sfiuamiforni plato 

 tapi-rin-j. Second pair of maxilla? ha\-ing the basos comph^x ; it 

 is formed like a hollow chamber with a longitudinal septuin. tlie 

 edges ciliated ; ischium tapenng. and plumosely ciliated upon 

 the inner margin. Maxillipeds having the carpus intenially 

 dilated, compressed, abundantly covered with fascicidi of long hairs 

 strongly serrated upon the lower margin ; i)ropodos internally di- 

 lated, compressed, fringed with creniilated hairs ; dactylos absent. 

 First pair of guathopoda having the nieros short, the carjius long, 

 and the propodus about half as long as the caiinis ; dactylos 

 unguiculate ; hairs upon the propodos long, lobod at the point, 

 and fiu-nished with a subapical appendage. Second pair of gna- 

 thopoda scarcely differing from the fii-st pair except that the dac- 

 tylos is nidimcntary ; the haii-s upon the inferior margin of the 

 caipus arc of two kinds, one long and slender, the other short, 

 stout, flat, curved at the point, and erenulate upon each margin ; 

 upon the propodos they arc short, lobed, and scn-ated along one side. 

 Two anterior pairs of pei-eiopoda resembling each other ; meros 

 l">luinosely ciliated ; carpus compressed, dilated, ciliated upon the 

 inferior side, and furnished with a few stout spines ; propodos 

 compressed, dilated, and furnished along the apical margin with 

 short stout sj^ines. Third pair of pcreiopoda having the meros 

 and carpus distally produced posteriorly, scaly, the margin of each 

 scale fringed with short spines or long plumose cUia ; propodos 

 not dilated ; anterior margin and apex studded with short strong 

 spines ; dactylos absent. Fourth pair of pcreiopoda haWng the 

 meros posteriorly and the caq)us anteriorly dilated and covered 

 with fasciculi of short spines and long simple hairs, the latter 

 marginal ; propodos cylindrical, and studded posteriorly and on 

 the apex with bunches of short strong spines. The posterior 

 pair of pcreiopoda diflPer from the preceding in ha\-ing the meros 

 dilated posteriorly and distally, and the projwdos compressed and 

 slightly dilated. Three posterior pairs of pleopoda short ; rami 

 subequal, spinous ; a fasciculus of long plumose hairs near the 

 inferior distal margin of the peduncle of the penultimate pair. 

 Telson deeply divided, the divisions dilated so as to overlap each 

 other ; apex covered with spines ; a small, lateral, compressed, 

 spinous lobe upon each side at the base. 

 Ix'Ugth ^Jths of an inch (exclusive of the inflected portion of tho
