The carapace is wider than long, very flat and con- 

 tracted behind. The fronto-orbital border occupies almost 

 the whole breadth of the carapace ; the front is spin\'. 

 The basal antennal joint has on the outside a prolonga- 

 tion which, inserted between the inferior orbital border 

 and the front, is prolonged as far as the angle of the 

 orbital cavity. The movable part is inserted under the 

 front, and is excluded from the orbit. The basal joint 

 of the internal antennae is wide, but very slightly elevated. 

 The buccal cavity is wide in front ; it is notched on each 

 side for the passage of the water from the branchial 

 chamber. The fourth joint of the external maxillipedes 

 is wider than long. The first pair of legs is short, and 

 the fourth joint is hid under the carapace ; the fingers of 

 the pincers are pointed. The walking legs are short, 

 compressed, and the last joint is curved and pointed. 



The abdomen of the male is seven-jointed.
