recurved all round, and beset with numerous very long and 

 strong spines, of which those on the latero-anterior margin 

 are regular, longer than the others, and six in number on 

 each side, including that immediately at the outer side of 

 the orbit. The surface is also covered with tubercles and 

 spines ; the regions distinct and elevated, excepting the 

 hepatic, which are very slightly developed. Rostrum one- 

 third as long as the rest of the carapace, projecting for- 

 wards, furnished with four spines at the base, of which 

 one is placed above and another (the longest) beneath, 

 and one on each side ; two other lateral spines near the 

 middle, and two terminal ones which are divergent. There 

 are no distinct orbits ; the eyes are contiguous at the 

 insertion of their peduncles, and stand forwards and out- 

 wards, being protected above by the rostrum and the 

 anterior margin of the carapace, between them by the 

 long inferior spine of the rostrum, and at the outside by 

 a strong spine. The anterior pair of legs are unequal, in 

 some cases the right, in others the left being the larger ; 

 they are covered with strong sharp spines, those on the 

 inner margin the largest ; the wrist nearly cylindrical ; the 

 larger hand robust, nearly as broad as it is long; the 

 fingers somewhat spoon-shaped, and furnished with small 

 tufts of hair above, the opposing margins tuberculated. 

 The second to the fourth pair of feet long, cylindrical, 

 furnished with strong spines ; the terminal joint compressed, 

 slightly curved and acute ; the fifth pair diminutive and 

 without spines. The abdomen is coriaceous, with regular 

 patches of crustaceous matter, representing the segments ; 

 the first is entirely crustaceous, very short, and extending 

 quite across the breadth of the abdomen, linear and spinous ; 

 the second, fourth, and sixth joints are represented each by 

 a pair of broad oval patches towards the margin ; the
