Carapace longer than wide, five-sided, rather produced and 

 acuminated in front. Upper surface with four elevated spines, 

 rather thickened and blunt at the ends, the first about midway 

 between the fore and hind part of the carapace, directed upwards 

 and slightly backwards ; behind it another spine much longer 

 and one on each side of this, on the hind margin of the carapace ; 

 in the middle, two spines directed upwards and slightly backwards ; 

 the first and second spines from before backwards, moderate in 

 length ; the third placed in the centre of the carapace, long, 

 vertical, and rather sharp-pointed; the spines situated in the 

 raised prominent tuberosity of the branchial region, long, stout, 

 erect, and directed a little outwards and backwards ; entire 

 surface of the carapace covered with blunt, sub-conical tubercles. 

 Breadth of carapace about four lines, length about four lines and 

 a half. Front small, depressed very considerably, rather short, 

 somewhat obtuse, deeply concave in the middle, with a slight tooth 

 on each side. Pore-legs very long in comparison with the rest of

 are smooth, rounded on the sides, and more spinous on the 

 angular crests. Hind-legs very slender and smooth, rounded 

 above and below, with the claws long, fine, slightly flattened and 

 very sharp. [Adams and White.]
