circlet, flagellum barely as long as peduncle, ca. 21 -jointed in c?,ca. 17 

 in ? . 



Upper lip, distal margin strongly convex and setose. 



Lower lip, lobes short, broad, apically truncate, inner apical angle 

 rounded, setose. 



Mandible, cutting-edge with 2 large and 5 small teeth, secondary 

 cutting-edge in left 5-dentate, in right 3-deiitate, spine-row with ca. 5 

 spines. 



First maxilla, inner plate with 3 plumose setae, outer plate with 

 9 spines. 



Second maxilla, inner plate shorter and narrower than outer, more 

 pointed apically, with a large stout plumose seta at junction of inner 

 and apical margins. 



Maxilliped, inner plate with 3 blunt teeth on truncate apex, outer 

 plate not extending very much beyond inner plate (to middle of 2nd 

 joint of palp), 4th joint of palp quite obsolete. 



First guathopod in < , 4th joint without apical process, 5th longer 

 than 6th, with pellucid apical lobe, 6th not widening much distally, 

 subchelate, inner apex with a rounded lobe, finger (excluding unguis) 

 reaching to end of this lobe, with 2 setules on its inner apex, 

 unguis unusually long, as long as finger ; in $ , 2nd joint wider than 

 in (J , 5th without apical lobe, 6th simple, slightly tapering, finger and 



ungus as n 



Second gnathopod in $ , 6th joint large, cordiform, hind margin 

 short, bearing spines at equal distances apart, a very small defining 

 tubercle, first portion of palm evenly convex and bearing spines as on 

 the hind margin, the distal portion of palm concave, smooth, with a 

 strong triangular tooth, spiuuliferous at its apex, situate near the 

 hinge, finger as long as palm, curved, inner margin slightly emarginate 

 at the base ; in $ , 2nd joint rather strongly expanded on anterior 

 margin (half as long again as broad), 4th in the Dassen Island 

 specimens apically produced downwards as a narrow subacute lobe, 5th 

 broader proximally than distally and equal to 6th joint including its 

 apical process, which is rounded and slightly curved upwards, finger 

 and curved unguis very short. 



Second peraeopod, 7th joint sharply constricted, but its appearance 

 is better described as having a tubercle in middle of inner margin, 

 unguis long but not equal to 7th. 



Third peraeopod, 2nd joint expanded, rather broader than long, 

 hind margin evenly convex, setuliferous, 7th slender, unguis not equal 

 to 7th. 



Fourth peraeopod in <$ very long, 2nd joint enormously expanded,
