second and third joints together ; second joint rather longer than the third ; 
accessory flagellum two-jointed, armed with setae, hardly as long as first 
joint of flagellum. Each joint of antennule provided with setae, which 
on the flagellum after the eighth joint number seven, and display an 
unvarying arrangement. 
Antennae : the peduncle longer than the flagellum ; ultimate and 
penultimate joints of peduncle well provided with setae; the distal part of 
the flagellum joints carry about eight setae each, disposed in an unvarying 
sequence. 
Mandibles of unequal size and of slightly different structure on each 
side ; palp rather like that of Paracrangonyx compactus Chilton, except 
that the second joint is broader. 
Maxillala much like that of P. compactus : the endite of the first joint 
bears two plumose setae and a number of hairs on the inner margin. 
Maxilleped : not unlike that of P. compactus ; however, slenderer, and 
the seventh joint is shorter. 
Gnathopods well developed, subchelate; both pairs of about the same 
size and length ; the fifth and sixth joints of gnathopod I somewhat broader 
than those of gnathopod II. 
Pareiopods : numbers I and II subequal, shorter than the succeeding 
ones ; number V the longest ; second joint of numbers III, IV, and V broader
