Carapace about as broad as long, with three keels, the median one with 

 four strong spines, the first longest and placed on the upper margin of the 

 rostrum, the second nearly as long and situated immediately behind the 

 base of the rostrum ; the first, third, and fourth spines are directed obliquely 

 upward and forward, the second directly upward or a little backward. 

 The rostrum is short, not reaching the end of the first antennular seg- 

 ment, sharp and curved upward. The lateral keels are formed by four 

 spines; the foremost, on the anterior margin of the carapace near the 

 base of the antennae, is the largest, and is directed obliquely outward and 

 forward, more than half as long as carapace ; the three others are smaller 

 but sharp. There is a sharp spine at the outer angle of the orbit and 

 another on the outer side of the antenna at the base of the scale. 



Merus of first pair of feet with a strong superior terminal spine ; car- 

 pus with an outer, an inferior, and a smaller inner spine ; hand more 

 than twice as long as broad; anterior margin nearly transverse; spine 

 short. 



The abdomen is sculptured, first to sixth segments with a median keel,
