families, ^^gidae, Anilocridae, Saophridae and Cymothoidae, 

 excluding from the group the genera which were subsequent!}' 

 included by Hansen in the families Cirolanidae, Corallanidae, 

 Alcironidae and Barybrotidae. Hansen in 1890 makes the 

 Cymothoid group consist of six families, the four just 

 mentioned and the yEgidae and Cymothoidae, but it must be 

 observed that the Cymothoidae of Hansen includes the 

 Anilocridae and Saophridae as well as the Cymothoidae of 

 Schiodte and Meinert. Thus it will be seen that the family 

 Cymothoidae, with some variations in the spelling of the 

 name, has also had a diversified career, being sometimes 

 restricted and sometimes extended, so that nothing like 

 general agreement has yet been reached as to its limits. 

 Hansen distinguishes it from the ^gidae by the mandibles 

 being without accessory plate and with the first joint of the 

 palp inflated, and by the maxillipeds being always four- 

 jointed, with the last joint rather long and narrow and 

 sub-acute, and adds that the adolescent or adult animals of 

 this family may be further distinguished from the ^gidae 

 by the following characters : — both pairs of antennae having 

 the peduncle in general scarcely or not defined from the 

 flagellum ; all the pleopods with bare rami ; terminal segment 

 with bare margin ; uropods with margin of the rami bare at 

 least in the female ; the animals hermaphrodite.

From the other genera assigned by Schiodte and Meinert 

 to their family Anilocridae, this genus is distinguished by the 

 rounded or sub-truncate cuneiform front of the head, while the 

 Anilocridae in general are distinguished from the Saophridae 

 and Cymothoidae of the same authors by having the peduncle 

 of the uropods produced into a long inner spine.
