fourth or the outer margin of the fifth joint ; the slender sixth is 

 about twice as long as the still more slender seventh. The exopods 

 of the first four peraeopods, like those of the third maxillipeds, have 

 the peduncular joint narrow compared with the stout second joint 

 of the limb, while the first joint of the flagellum is unusually long, 

 and at least in that of the first paraeopods with a denticulate margin. 

 In the second peraeopods the third joint is short but outdrawn to a 

 conspicuous apical spine ; the fourth joint is much stouter but not 

 longer than the fifth, which together with the small sixth cannot 

 make up the length of the slender straight seventh joint. The third 

 peraeopods have the stout second joint much narrowed distally, 

 longer than the slender rest of the limb, in which the fifth joint 

 is considerably the longest, the seventh almost spine-like. The 

 fourth peraeopods are very like the third, but with the second joint 

 a little shorter and less narrowed distally, while the fifth joint is a 

 little longer than in the preceding pair. The fifth peraeopods are 

 very like the two preceding pairs, except for the absence of an 

 exopod and the strikingly different second joint, which is very 

 slender and not much longer than the fifth joint. 



The endopod of the uropods is rather less than two-thirds of the 

 length of the serrately margined peduncle, and carries nine spines 

 on its inner edge, the apex having a large spine flanked by two 

 smaller ones; the much narrower and shorter exopod has a slender 

 apical spine with a small one adjoining and a small spine or two on 

 its inner edge.
