the free edges of which are elegantly ciliated, the scales on the hand forming 

 several series : the inner edge of the carpus, both edges of the palm, and the 

 outer edge of the fixed finger are spinose : the finger-tips are markedly cor- 

 neous. 



The 2nd and 3rd legs exceed the chelipeds by about half their dactylus : 

 the anterior and upper surfaces of the long joints are covered with transverse 

 ciliated and pilose subsquamiform markings : there is a spine at the far end of 

 the anterior border of the carpus : the dactylus is stout and curved, that of 

 the 3rd pair is as long as the two preceding joints combined. 



The paired appendages of the first abdominal somite of the female are 

 L-shaped rods.

Carapace short, broad, well calcified in front of the cervical suture ; ros- 

 trum obtuse, leaving the ophthalmic segment exposed. Abdomen well deve- 

 loped, soft, spirally coiled. 



Eyestalks short and stout : eyes large : ophthalmic scales distant. Anten- 

 nal acicle of moderate length : flagellum very long and slender, naked or 

 sparsely setose. 



External maxillipeds widely separated at base : the exopodites of all 

 three pairs of maxillipeds are flagellate. 



The chelipeds may be of about equal length, but the right is stouter than 

 the left, especially in the male : the fingers move in a horizontal plane, and 

 the finger-tips are calcareous. 



The 3rd pair of legs are not, or hardly, subcheliform and have the subter- 

 minal "rasp " narrow : the 5th pair are minutely subcheliform and have the 

 usual subterminal " rasp."
