PILUMNIDAE. é 
carapace smooth and the chelipeds coarsely rough; in the deep median 
sinus of the front; in the denticulation of the lateral spines; in the lack of 
prominent spines on the anterior border of the arm. 
The genus Pilodius stands very near Pilumnus and Chlorodopsis ; it has the 
aspect of a Pilumnus, but the fingers are spoon-shaped instead of pointed ; 
the carapace is not so much subdivided into areolets as in Chlorodopsis, where 
the antero-lateral areolets are exceptionally rough and high. As for the 
arrangement of antennae and orbits, it does not in Pilodius differ much from 
some species of Chlorodopsis, although the movable part of the antenna is 
excluded from the orbit in the typical species of the latter genus.
