of the superior. The first pair of hands have the carpus 
rather longer than the propodos, 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, pl. 13a, fig. 1-8, from 
a specimen dredged on an oyster-bank of Port Louis; 
but in his description in Hist. des Crust. t. ili. 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.
