BRACHYURA. 
Acheus Cranchii. 
This species is spoken of by Bell as being rare, two specimens 
only having been recorded—one from Falmouth, the second 
from the south coast of Ireland. Certainly this little Crab is 
by no means uncommon off the coast of South Devon, in depths 
of from 6 to 20 fathoms of water, as we have taken it with the 
dredge in Plymouth Sound, and frequently had it brought in 
by the trawlers. 
Among the specimens that we dredged, two were taken from 
about 6 fathoms of water, near the Knap buoy, off the western 
end of the Plymouth Breakwater, which appear to belong to a 
very distinct variety. Our attention was first drawn to it from 
observing a peculiarity in its habit, differing from that of the 
known species, which is that it covers itself with weed, as we 
know is commonly done by animals of the allied genus Pisa. 
Certainly in Pisa this is no accidental circumstance, since all 
the spines are sharp-pointed and curved, thus forming strong 
hooks, on which hang the various kinds of weed.
