Carapax throughout imperfectly areolate, and surface cellulous, naked 

 ' antero-lateral margin imperfectly three to four lobed and excavated 

 with cellules, postero-lateral margin very short, concave. Anterior

Length of carapax of female, 3 lines; greatest breadth, 4'3 lines; 

 ratio of length to breadth, 1 : 143. The animal looks like a worn 

 pebble of cellular coral. The whole surface of the carapax is cellular; 

 and the legs, when drawn up, may be mostly concealed beneath the 

 carapax. Traces of the areolets may be made out over the back, but 

 they are not well defined. The surface between the low prominences 

 of the antero-lateral margin has in each case a deep hollow excavated 

 in it, The postero-lateral margin is quite concave, and the surface 

 against which the posterior legs rub is flat, making an angle with the 

 surface of the carapax above. The under surface of the body is very 

 short villous throughout, the outer maxillipeds included.
