mate and is rather less than twice as long as broad. The inner 

 edges of the last three segments and the greater part of the lower 

 face of the penultimate are thickly clothed with hair. 



The first peraeopods reach beyond the antennal scale by the 

 chela and the greater part of the carpus. The merus and carpus 

 are moderately stout, the latter slightly longer than the former and 

 17 times the length of the chela. The fingers are almost equal in 

 length with the palm. 



The second peraeopods (text-figs. 101&, c) are a little unequal,

but are identical in structure. They extend beyond the scale by 

 the greater part of the chela. The merus is unarmed at the distal 

 end of its upper border, but bears a strong tooth externally at the 

 end of the lower border. The carpus is very short and, as in 

 C. graminea and C. superba, is provided with a stout ventral tooth. 

 In the female the distal margin of the carpus on its upper and 

 outer aspect is cut into a number of very minute teeth ; in the 

 male, which is much smaller, these are not visible. The chela is 

 swollen and is widest near the base. The palm is from 2 to 2*3 times
