The length of the carapace is very little more than its 

 greatest breadth. The uptilted rostrum is a good deal more 

 than half the lengtli of the carapace and more than double 

 the length of the slightly divergent supraorbital spines ; it 

 extends backwards as a faint carination of the front half of 

 the gastric region. The anterior border of the cara])ace on 

 either side of the rostrum is convex and slightly oblique ; 

 the posterior border is smooth ; the lateral borders are armed 

 with 7 (2 + 3 + 2) spines. The transverse ridges are strongly 

 developed and finely and faintly beaded, and are thickly 

 fringed with setse, some of which at regular distant intervals 

 are long, Tiie gastric area is armed in front with a convex 

 row of spines, of which only two, namely those in the imme- 

 diate rear of the supraorbital spines, are conspicuous, while 

 of the others the outermost one on each side is the largest 

 and stands far back. 



A small spinelet is present on each side immediately behind 

 the bifurcation of the cervical groove. The cardiac area is 

 usually well defined by a zigzag incision. 



The abdominal terga have the transverse ridges well 

 developed and setose ; the second only is armed, having on 

 its anterior margin a row of 8 distant spinelets. 



The eyes are large, the major diameter of the moderately 

 flattened corneal region being between one third and one 

 fourth the length of the carapace; conspicuous sette fringe 

 the corneal region, and the pigmentation of the latter varies 

 from slate-grey to cinnamon-brown. 



The spines of the basal joint of the antennulary peduncles 

 are long and needle-like. 



The antennal peduncles are smooth ; the basal joint has its
