CHLORODIUS IMBRICATUS, N. S. Anteriorem regionem 

 carapacis habens imbricatani irregulariter ; posteriorem planam ; 

 carpuin et propodon pereiopodimi paris prinii rugosa. 



Carapace having the posterior portion smooth, 

 the anterior being rough with flattened promi- 

 nences, that form an irregularly imbricated sur- 

 face. Anterior margin five-toothed, the central 

 tooth being the largest, the posterior the most 

 prominent. A small secondary tooth stands 

 upon the anterior surface of the fourth and fifth 

 teeth. The first pair of pereiopoda are short and 

 robust ; they have the carpus deeply corrugated 

 upon the external surface; a slight rib is also 

 present upon the carpus of each of the four suc- 

 ceeding pairs of pereiopodos. 



Only a single specimen of this pretty little 

 species was obtained. It was dredged in about 

 eight fathoms of water, in Esquimalt Harbour.
