PLATE XV, FIGURES lA lAiv. PLATE XVI, FIGURE 3. 



The carapace and pleon are densely covered with short plumose 

 hairs. There is a dorsal gastric spine behind the rostral carina, 

 which rises abruptly ; the rostrum, which is directed a little 

 obliquely upward, is shorter than the carapace. It has eight to 

 ten dorsal teeth, all in front of the posterior margin of the orbit. 

 There are two small denticles on the posterior margin of the orbit, 

 and a much larger, angular, acute antennal spine just below it; 

 also a small acute spine at the lower margin of the antennal sinus ; 

 hepatic spine small, acute, appressed. 



The legs of the third pair reach as far forward as the tip of 

 the rostrum, being longer than the second pair by at least the 

 length of the chelae ; the chela is two-fifths the length of the carpus 

 and scarcely thicker. Fifth legs are longer than the fourth. 



The third to sixth segments of the pleon have a dorsal carina; 

 on the fourth and fifth segments the carina is divided by a median 

 incision at the posterior end into a pair of denticles ; sixth segment 

 strongly compressed. The telson is regularly tapered to an acute 

 tip, which has an elongated spine on each side; three pairs of 

 movable spines, the posterior much the largest, arise in front of 

 the lateral spines and reach beyond their tips. 



The length of the Bermuda type-specimen (female) was 57 mm; 

 length of carapace and rostrum, 19.4 mm; length of rostrum, 9; 

 of carapace, 7.5 ; of third perseopods, 18.2 ; of antennal scale 

 10.0 mm.
