very lobular. The lobes of the anterior portion are 

 prominent, covered with pointed tubercles or with spines, 

 between which extend wide grooves, deep and smooth. 

 The front is formed of two lobes very advanced, and 

 separated in the middle line by a notch relatively wide. 

 The frontal and suborbital borders bristle with spines. 

 The antero-lateral borders are long, regularly bowed, and 

 divided into five lobes armed with three or four spines ; 

 the external orbital angle is also spiny. The postero- 

 lateral borders are concave. The posterior border has a 

 row of tubercles. The basal antennal joint has spines. 

 The fourth joint of the external maxillipedes is short, 

 wide, and deeply notched on the inside for articulation 

 with the fifth joint ; its anterior and internal border is 

 slightly toothed. The first pair of legs subequal ; the hand 

 is covered with spines upon the superior and external face ; 

 the fingers are short, spinous, black, with a white ex- 

 tremity; the black, in males, extends upon almost the 

 whole of the hand. The fifth joint is spiny. The walking 

 legs have many spines.

Carapace broad and deeply lobulated both in front 

 and behind ; the lobes forming prominent granulated 

 nodes, mostly of nearly equal size, about forty, including 

 the antero-lateral teeth. These lobes are strongly convex 

 in the anterior, but flattened in the posterior, regions of 

 the carapace. The furrows separating them are wide and 

 deep, and more or less thickly pubescent. The median 

 gastric lobe, which is usually long and slender, reaching
