of the superior. The first pair of hands have the carpus 

 rather longer than the propoclos, and ciliated along the 

 inferior margin; the propodos has the inferior digital 

 process liberally ciliated over the surface, and more so 

 along the margins ; the dactylos is curved, smooth, and 

 inversely corresponding in form to the margin of the 

 opposing finger. The second pair of hands have the 

 margins of the carpus and propodos fringed with strong 

 spines, and the finger planted in the middle of the ex- 

 tremity of the flattened propodos. The succeeding legs 

 appear not to differ much from those of the preceding 

 species, except the posterior pair, which, instead of having 

 the propodos fringed with cilia, have it armed with short, 

 stiff spines, that increase in length towards the distal 

 extremity. In most other points this species appears to 

 differ but little from the preceding. 



"We have seen but a solitary specimen, which was 

 sent to us by our esteemed correspondent the Rev. A. M. 

 Norman, who obtained it on the coast of Northum- 

 berland. 



This specimen was a female, and carried a mass of 

 large, circular, orange-coloured eggs between the second 

 and penultimate segments of the pereion, beneath a 

 transparent membranous sac. 



M. Milne Edwards first described this species in the 

 Ann. des Sci. Nat. t. xiii. p. 288, pi. ISA, fig. 1-8, from 

 a specimen dredged on an oyster-bank of Port Louis ; 

 but in his description in Hist, des Crust, t. iii. p. 141, 

 he gives the coast of Brittany as the habitat. 



The extreme paucity in the number of the specimens 

 both of this and the preceding species, that have been 

 recorded, induces us to believe that the true habitat and 

 habits of the genus have yet to be discovered.
