 The distinguishing characters of this genus appear to be as 

 follows : The flagellum of the second antennae is two-jointed ; 

 the mandibular palp is three- jointed ; there are branchial 

 vesicles only on the third and fourth segments of the perseon, 

 and in connexion with these vesicles there are single-jointed 

 quite rudimentary limbs ; the third perseopods are normal ; 

 pleon in the male with one pair of appendages; sixth and 

 seventh segments of peneon in coalescence. 



It is on the last character that Dr. Mayer lays most stress.
