68 B. IV. Kunkel, 



extending slightly beyond apex of tirst joint of palp, outer margin 

 convex and apical margin rounded and provided with numerous 

 submarginal setae ; palps strong, first joint with outer margin about 

 3 times as long as inner, second joint nearly twice as long as first 

 and ver}^ broad on account of presence of broad lobe on inner side 

 which is produced distally and bears numerous long, stout setae at 

 apex and distal part of inner margin ; third joint about as long as 

 first, provided with broad, rounded lobe on inner side at distal end 

 so that joint is much broader distally than proximally, outer apex 

 also provided with small, rounded lobe, distal margin and lobes 

 armed with many long, stout setae ; fourth joint about as long as 

 third, clawlike, with concave margin provided with numerous setae. 



In female, first gnathopods somewhat smaller than second ; epim- 

 eron rather deeper than long with anterior ventral angle rounded 

 and not greatly produced ; second joint moderately stout, with an- 

 terior margin slightly concave, posterior margin convex and prox- 

 imal end much thinner than distal, anterior distal angle produced 

 to 'form rounded lobe, posterior margin with 2 rather stout pectinate 

 spines near middle ; third joint short, with posterior distal angle 

 provided with long pectinate spine and several setae ; fourth joint 

 subrectangular, more than twice as long as broad, provided with 

 several pectinate spines on distal margin ; wrist ^/a as broad as long, 

 articulating with fourth joint by entire anterior margin of fourth, 

 posterior margin forming a semicircular lobe which is provided with 

 closel}' set row of pectinate spines ; hand subrectangular, slightly 

 broader at distal end than proximal, posterior margin provided with 

 row of pectinate spines occupying middle third of margin which at 

 this point is slightly convex, outer surface of hand provided with 

 diagonal row *of stout, plumose spines, palm slightly oblique and 

 convex, provided with several setae and 2 prehensile spines ; finger of 

 usual form, short and stout and provided with several setae on con- 

 cave margin. 



Second gnatho])ods similar to first but having epimeron subrect- 

 angular with ventral margin rounded and palm of hand slightly 

 more oblique than that of first ; whole appendage stouter in all respects 

 than first. 



In male, first gnatho])ods with e])imeron having anterior ventral 

 angle not greatly produced ; second joint stout, with anterior margin 

 straight and posterior margin convex with several sharply pointed 

 spines at nearl}- equal distances from each other; third joint about 

 as long as wide ; fourth subrectangular with anterior margin forming 

 articulation with wrist which is triancfular, much longfer than wide
