The genus Actasodes, which is not sustained by A. Milne Edwards and by some 
other authors, in Dana’s system represents in the Chlorodiinse the genus Actasa in the 
Xanthinse, which it resembles in the transverse and distinctly lobulated carapace and in 
the rounded lobes of the antero-lateral margins, also in the structure of the orbits, 
antennse, maxillipedes, and in other essential characters ; it is, in fact, only distinguished 
from Actasa by the structure of the chelipedes, whose fingers are excavated in the adult 
at the apices, and is connected with that genus by almost insensible structural gradations. 
The species are small, and inhabit the coasts and islands of the Indo-Pacific region ; 
one species, Actaeodes fdba, Dana, occurs in the Atlantic region. Most of them are 
apparently somewdiat local in distribution, but the only species [Actasodes tomentosus ) 
collected by the naturalists of the Challenger Expedition, ranged from the Red Sea and 
the Mauritius eastwards to the Sandwich Islands. 
Besides the species described by Dana which are placed by Milne Edwards in Actasa, 
the following are, I think, referable to Actaeodes : — 
Actaeodes nodipes, Heller, perhaps = Actaeodes speciosa, Dana. Red Sea. 
Actaeodes poly acanthus, Heller. Red Sea. 
Actaeodes fragifer (White). Philippine Islands. 
Actaeodes pubescens (Milne Edwards). Mauritius. 
Actaeodes variolosus (A. Milne Edwards). Upolu, Samoa Islands. 
Actaeodes tomentosus (Milne Edwards).
