Since this species is only known from Studer's brief, yet for 

 purposes of identification quite sufficient, description, the details of 

 the appendages may here be given. 



First antenna with 5-jointed flagellum, the 1st joint much the 

 longest, equal to the 1st peduncular joint. 



Second antenna with 4-jointed peduncle, Studer having evidently 

 overlooked the short 1st joint, 4th joint equal to 2nd and 3rd 

 together, flagellum ca. 24-jointed. 



Upper lip transverse, twice as broad as long, clypeus triangular 

 with a projecting point. 



Mandible as figured by Hansen for the other species of the genus, 

 palp with 2nd joint 2| times length of 1st, 3rd joint a little shorter 

 than 1st, 2nd and 3rd joints setose. 



First and second maxillae and maxilliped as figured by Hansen. 



First peraeopod with 3rd and 4th joints strongly produced 

 externally, 4th joint underriding 5th, inner margin with ca. 8 stout, 

 blunt spines, inner margin of 6th joint with 6 spines. 



Seventh peraeopod, inner margin of 3rd joint with 5 marginal and 

 3 submarginal groups of 3 spines each, innei- apex with 6 spines, 

 outer apex with 3-4 spines, 4th joint with 3 marginal and 3 sub- 

 marginal groups of 5 spines each, inner apex with ca. 9 spines, outer
