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 peraeon, 



and in connexion with these vesicles there are single-jointed 



quite rudimentary limbs ; the third peraeopods are normal ; 



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



seventh segments of perieon in coalescence. 



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