slightly hooked. Lower lip, inner lobes broad, outer with short mandibular processes. 

 Maxilla 1 , outer lobe with numerous spines, inner ovate, with one strong seta in middle 

 of inner margin, palp 2-jointed, ist joint strong, 2nd shorter, with three strong plumose 

 setae apically. Maxilla 2, both lobes ovate, apically rounded, inner with an oblique row 

 of plumose setae as well as the marginal row. Maxilliped, inner plate truncate, outer 

 ovate, with close-set curved spines on inner margin, 2nd joint of palp strongly expanded 

 on inner margin, 3rd angularly expanded on outer margin, 4th terminal, slender. 



Gnathopod 1 slender, 4th joint expanded on lower margin, with thick fringe of long 

 simple setae, 6th fusiform, narrowing rather rapidly distally, with thick brush of simple 

 setae surrounding the short curved dactyl. Gnathopod 2 slightly more slender than
