Technical description : Carapace widest anteriorly, three-fourths 

 as long as wide; the regions clearly defined. The frontal border is 

 wide, equal to about two-thirds of the greatest width of the carapace, 

 cut into two lobes with the frontal margin slightly rounded and set 

 apart from the orbital angle by a distinct wide sulcus ; the preorbital 

 angle is deflected and touches upon the inferior orbital angle, com- 

 pletely closing the orbital hiatus. The superior orbital margin is ellip- 

 tical with indications of two brief closed sinuses ; the postlateral tooth 

 is acute, spinelike and in addition to this there are four similar but 

 successively smaller spines on the anterolateral border. The regions 

 of the carapace are distinctly defined. The frontal region, also the 

 hepatic and outer anterior branchial regions bear numerous coarse 

 spinose granules and interspersed among these are many solitary stiff 

 setae. Similar spinose granules are abundant. The sidewalls of the 

 carapace and especially the region adjacent to the epistome also bear 

 numerous coarse spinose granules. The male belt is triangular, seven- 

 segmented. 



The eye is large with a very flexible articulation of the stalk; the 

 cornea terminal, set obliquely. 



The antennulae are not very large and fold transversely within the 

 thick margined fossett ; the interantennulary septum is wide.
