Eyestalks piriform, dorsally beset with transverse ciliated lines, not two- 

 thirds the length of the anterior border of the carapace, much shorter than the 

 antennal peduncles. Eyes large, reniform : ophthalmic scales thin, foliaceous, 

 dorsally concave, fringed with setae, distant. 



The antennal and antennular peduncles are of nearly equal length, the 

 former are stout and their dorsal surface has a squamose appearance : antennal 

 acicle curved, surpassing the eye, setose but not plumose : flagellum very long, 

 nude. 



Chelipeds and legs ciliated and tomentose, the edges of the legs 

 plumose as if for swimming. 



The chelipeds, which are subequal and not twice the length of the 

 carapace, are decidedly slender, none of their joints being so stout as the 

 meropodites of the 2nd and 3rd legs : they are covered with squamiform 

 ciliated markings, and their only armature consists of a row of spines in the 

 distal half of the inner border of the wrist, and another shorter longitudinal 

 row of spines in the distal part of the outer surface of the wrist : the wrist 

 is shorter than the merus and a little longer than the palm : the palm is 

 much longer than broad and a little shorter than the fingers. 



The 2nd and 3rd legs surpass the chelipeds by almost the whole length 

 of their dactylus : the merus and carpus and propodite are broad, stout and 

 compressed, as if for swimming, and they are covered with ciliated squamiform 

 markings which on the propodite and posterior part of the carpus run very 

 obliquely : a thin, fine, smooth crest separates the upper from the outer 

 surface of the propodite ; the dactyli are narrow, curved and compressed, 

 those of the 3rd pair, which are the longest, being as long as the two preced- 

 ing joints combined : except for a row of spines on the anterior border of 

 the carpus, and sometimes also on the anterior border of the propodite, the 

 legs are not spinose. 



The vas deferens (left) is of relatively enormous size and forms a rigid 

 coil of two nearly complete turns. 



Length of carapace 16 millim.
