fissure above the external angle of the orbit, and a tooth 

 beneath that cavity. The latero-anterior margin has four 

 strong teeth, the bases of which are long ; the first situ- 

 ated beneath the line of the orbit, the second furnished 

 near its base with a tubercle or small secondary tooth, thus 

 appearing almost as if double ; the third occupying a larger 

 portion of the margin than either of the others, and the 

 last the smallest. The latero-posterior margin nearly as 

 long as the latero-anterior. The first pair of legs are 

 robust and nodulated ; the hand has several small conical 

 teeth on its upper and inner edge. The claws are smooth 

 and polished, strongly denticulated and internally hollowed 

 at the extremity, the denticles of each finger shutting into 

 the interspaces of the other ; the moveable finger much 

 curved on the upper side ; the wrist largely nodulated ; the 

 second and third pairs of legs much shorter than the first, 

 terminating in a strong, sharp, curved nail ; the fourth and 

 fifth pairs are doubled back over the posterior part of the 

 carapace, flattened, and each terminating in a sharp, tole- 

 rably perfect, double claw. The abdomen in the male is 

 much curved longitudinally, and the joints are distinct; 

 the terminal one broader than it is long. In the female 

 the abdomen is extremely broad and much curved ; each 

 joint elevated in the centre, and on each side. The whole 

 animal, body and limbs, covered with dense short hair, 

 which in the young state is of a buff colour, and in the 

 adult dull brown. 



Length of the carapace of a full grown male two inches 

 and a half, breadth three inches. 



I have carefully examined the hair with the microscope, 

 in individuals of various ages, and have not found in any 

 one instance the club-shaped hair assigned by Dr. Milne 

 Edwards to this species. The hair is in all cases setaceous,
