b4 CRUSTACEANS OF THE 



lateral border , is nearly as long as the outer margin of 

 the penultimate tooth. Just as in Menippe Fanope, the 

 straight postero-lateral borders strongly converge backward, 

 so that the slightly concave posterior margin ofthecepha- 

 lothorax is scarcely as wide as the front. 



The basal joint of the external antennae is small and 

 even slightly more distant from the front than it is itself 

 long; the second, much smaller joint reaches scarcely the 

 front and the third joint is narrower than the orbital 

 hiatus ; unfortunately the flagellum is broken , but it is 

 certainly as long as the orbits are broad. The internal 

 antennae (Fig. 2*) are a little oblique , the epistome is 

 short. The endostome is faintly ridged, the ridges being 

 only distinct on its posterior part. 



The external maxillipedes (Fig. 2^) are covered every- 

 where with a close microscopic granulation and a few fine 

 hairs are distributed over them ; they have about the same 

 form as those of Menippe Rumphii from the Indian Ocean. 



The fore edge of the merus-joint is slightly convex, 

 the antero-external angle is obtuse and the outer margin 

 is somewhat concave. 



The whole under surface of the carapace, between the 

 lateral margins and the buccal frame, presents the same 

 close microscopic granulation as the upper surface; the 

 granules on the internal infra-orbital lobe are a little larger 

 and near the lower border of the orbits the surface is 

 somewhat pitted (Fig. 2'''). 



The abdomen of the female is a little broader than 

 that of Menippe Panope , it presents its greatest width 

 at the penultimate joint and the terminal joint is semi- 

 circular; the seven joints are quite smooth, though some- 

 what pitted near their lateral- and anterior margins. 



The chelipedes difler from those of Menippe Panope es- 

 pecially by their different granulation. They are, 

 as in Herbst's species , massive and unequal , the right 

 being the larger. The strongly curved upper margin of the 

 quite short arm of the right leg, which scarcely extends
