what tapering with apex truncate and provided with about 8 branched 

 (antler-Hke) spines ; inner plate small, triangular, with 3 spines api- 

 cally. Second maxillae of usual form with oval plates, outer plate 

 broader distally, inner one broader proximally. Maxillipeds with 

 4-jointed palp, second joint long and slender, more than 4 times as 

 long as broad, third joint as long as fourth including terminal spine ; 

 outer plate rather narrow and slender, reaching nearly to end of 

 second joint of palp, provided on inner margin with row of closely 

 set toothlike spines which become longer toward distal end of plate 

 where they become plumose ; inner plate rectangular, with plumose, 

 spines on apical margin and distal portion of inner margin, which 

 bears at distal end a submarginal toothlike spine and external to 

 this a fascicle of simple setae. 



In male, first gnathopods with epimeron which is higher than 

 long and which projects strongly anteriorly, with a short seta just 

 behind anterior ventral corner; second joint moderately long with 

 several setae near middle of posterior margin ; third joint slightly 

 longer than broad with fascicle of setae near distal end of posterior 

 margin ; fourth joint short with posterior margin very convex so 

 that joint is ^/s as broad as long, posterior margin with numerous 

 setae on distal portion ; wrist subrectangular, widening somewhat 

 toward distal end, as broad as hand and slightly longer, posterior 

 margin with 8 or 9 fascicles of slender setae which increase in 

 length distally, surface of wrist provided with many fascicles of 

 short simple setae and longer pectinate spines ; hand oval, with 

 more or less convex palm passing by even curve into posterior 

 margin, provided with 2 prehensile spines, posterior margin with 

 3 fascicles of setae, palm finely serrated and provided with numerous 

 submarginal setae, surface of hand and anterior margin further 

 furnished with fascicles of setae ; finger of usual form with single 

 seta on outer margin near base and 5 or 6 blunt spines on inner 

 margin. 



Second gnathopods with epimeron about as broad as long, with 

 ventral margin slightly convex and furnished with 4 or 5 setae; 

 second joint long, with posterior margin convex and furnished with 

 4- or 5 setae placed at equal distances from each other ; third joint 

 somewhat longer than broad ; fourth joint twice as long as broad, 

 broadening somewhat distall}', with posterior margin elongated to 

 form a sharp projection having 2 setae at base ; wrist triangular, 

 not as wide as hand, with posterior margin rounded to fit internal 

 to projection on fourth joint, rounded portion covered with setae
