Antenna; minute. Antennal peduncle slightly elongated, the joints bearing acute 

 spines on their anterior and posterior faces. 



Chelipedes slender, one and two-thirds longer than the carapace and rostrum, 

 and bearing a few spines. Fingers not gaping, and not half the length of the 

 propodus. Colour yellowish, with three longitudinal dark purplish bands on the 

 carapace, and one on either side of the chelipedes and legs.

 Miers (26). 



Rostrum slender and stiliform, with a well-developed supra-orbital spine on either 

 side of the base. Carapace with the surface usually spinulose. and the cardiac area, as 

 a rule, distinctly circumscribed. 



Chelipedes and ambulatory limbs elongated and slender. One or more of the 

 abdominal segments usually with a series of spinules on the antero-dorsal margin. 



Very many members of this genus are deep-sea forms, extending down to 

 1,300 fathoms. A few are littoral, and occur in the crevices of rock or coral.

Carapace a little elongated, and covered with a series of more or less continuous 

 pubescent striae. Edges of carapace armed with seven or eight spines. Rostrum a 

 slender, conical, elongated, entire rod. Behind the rostrum, on each side, are four 

 large spines, slightly less than the rostrum, and decreasing in size posteriorly. Eyes 

 fairly large, and overhung by a few setse. Peduncles rather short. Chelipedes long 

 (twice as long as the carapace, including the rostrum), slender and hairy. The merus 

 is elongated and bears three spines on its internal edge, and a few smaller ones on its 

 outer edge. Carpus shorter than the merus, with one large spine on its anterior edge, 

 and a row of about four smaller ones on its outer surface. Propodite as long as the 

 fingers, with a number of smaller spines on both its inner and outer edge. Fingers 

 gaping. Abdomen unarmed.
