large, broad in the first half, then tapering to a fine point, which 

 reaches much beyond the much narrower, subequal rami of the 

 third pair. These are unarmed, more than twice as long as their 

 peduncle, the inner the broader. They reach considerably 

 beyond the long, proximally broad, distally tapering telson, which 

 ends in a fine point. 



The single specimen, a female with narrow fringed marsupial 

 plates, measured about 3 ram. In the other two species the 

 length of adult female is given as 6 mm. 



Locality. — Off Wata Mooli, 54-59 fathoms.

To the fifteen genera of this family defined in " Das Tierreich" 

 the appendix adds Bouvierella, Chevreux, 1900, and Oradarea, 

 Walker, 1903, to which, in 1908, Professor Holmes further adds 

 the genus Gracilipes, and in 1909 Walker provisionally placed 

 in this family the genus Chagosia. I have already pointed out 

 the likeness between Walker's Oradarea and Leplamphojnis, Sars, 

 Djerboa furcijoes, a new genus and species in the family Ponto- 

 geneiidee instituted by Chevreux for an Antarctic specimen, 

 diflers from Oradarea longimana, Walker, in having the telson 

 not entire but deeply cleft, and in some other points, but in 

 general shows a remarkable similarity.

A single specimen, female, of this species, measuring 6 mm. or 

 a little over, was dredged by the " Challenger " at a depth of 127 

 fathoms off Kerguelen Island. It does not appear to have been 

 met with again till obtained by the " Thetis." This specimen 

 shows no signs of being a female. Otherwise it appears to be in
