THE VOYAGE OF H.M.S. CHALLENGER. 
Philippines ; Etisus punctatus, Jacquinot and Lucas, from Mangareva Island ; Etisus 
dejiexus, Dana, from the Fijis ; Etisus dentatus, Milne Edwards, from Natal and the 
Mauritius to New Caledonia and the Fijis ; also perhaps Etisus anaglyptus, Milne Edwards, 
from Australia and the Philippines, and Etisus rhynchophorus (A. Milne Edwards), from 
Japan, adult examples of which are distinguished from the typical species of Etisodes, to 
which genus they are referred by A. Milne Edwards, by the broader transverse carapace 
and the greater dilatation of the basal antennal joint, which is not so greatly reduced 
at its antero-external angle as in Etisus.

Islands, Honolulu, reefs (a male). 
The colour of this species is subject to very considerable variation. The ground 
colour of the three specimens in the Challenger collection is yellowish-brown (in spirit), the 
adult male from Tongatabu has the carapace punctulated with spots of a brownish-red.

In this genus, which represents in the Chlorodiinse in Dana’s classification the genus 
Liomera in the Xanthinse, the carapace is very widely transverse, longitudinally convex,
