Figs. 7-38. 
Carapace wider anteriorly than posteriorly, and about as long as its width 
measured between the bases of the third and fourth pairs of legs. 
Surface thrown into five transverse wrinkles ; the first depression runs directly 
across the carapace just behind the orbits; the second is the cervical suture; 
the third is parallel to, and not far from, the second, the fourth is behind the 
cardiac region. There is a short deep longitudinal depression either side of the 
mesogastric area. The surface is covered with scabrous granules which are 
larger on the more elevated portions. 
Front cut into two broad rounded lobes. Antero-lateral border with three 
teeth, including the orbital angle, the third rudimentary. Second tooth pro- 
jecting laterally more than the first. Behind the second tooth, the margins 
are sinuous and convergent. Posterior border raised, entire. 
Upper border of the orbit with two notches, the inner one the deeper ; 
anterior margins of inner and outer orbital angles concave; lower border with 
two broad and deep notches. The end of the basal joint of the antenna forms 
a large lobe visible in a dorsal view, either side of the front. There are three 
lobules on the eye-stalk, and a large bilobed one at the antero-external angle
