_A specimen, of which the carapace is 18 mm. broad by 11 mm. 
long, was taken by Mr. H. W. Bell Marley at Vetch’s pier. It 
prettily answers, after being in spirit for a considerable time, the 
description given by Riippell for the colour variety which he named 
Carpilius marginatus, the dorsal surface being a fine red surrounded 
by a milk-white border. The antero-lateral margin is entire.

Miers, after giving the definition of the genus, remarks that it is 
distinguished “from Atergatis by the non-carinated and non-cristated 
antero-lateral margins of the carapace, and joints of the ambulatory 
legs.”
