The second leg has the basis as long as the remaining joints, the merus 
longer than the carpus or propodus, which are subequal in length. Setae of 
posterior peraeopods as in fig. 3, I. 
The peduncle of the uropoda is as long as the telsonic somite and as the 
exopod, which is slightly longer than the endopod. 
Submature examples have the usual characters of immaturity, the peduncle 
of the uropods is shorter than the rami, etc. In some examples of both sexes, 
about 8 mm. long, the ridges and elevations of the carapace are more defined and 
the surface is coarsely reticulate (fig. 48 D-E).

In his key to Cyclaspis spp. Stebbing (1913, pp. 29-80), from Sars’ descrip- 
tion, separates australis from exsculpta, ete., in having ‘‘Ridges not enclosing 
quadrilateral areas on carapace.’’ These areas are present though faintly 
marked. 
In the grouping here adopted, this species has a quite characteristic facies; 
considering both adults and subadults, it has the sculpturing of the carapace less
