FISH AND CRUSTACEA OBTAINED IN CORNWALL, 425 
water left by the receding tide), but the second was taken in deep 
water in my trammel, enclosed in a sort of nest made of sea-weed 
and sand, which had all the appearances of being worked up arti- 
ficially. I noted of the hindmost pair of legs of this little crab that 
it never used them, or even displayed them whilst alive. They 
were kept tucked up under the back of the carapace (or close along- 
side of it), over the other legs, and were but very rarely moved, and 
never both together. 
I had a second Long-legged Spider Crab from the deep water 
covered with little bits of sea-weed, not, I think, growing, but 
stuck on to it in some way. Most of the weed consisted of little 
fragments of some of the common Delessaria. 1 took also the 
Common Crab (C. pagurus), the Lobster, the Cray-fish, the Velvet 
Swimming Crab (the Blue Harry, P. puber), and on my last day the 
rare swimming crab, Portunus Holsatus, the Livid Swimmer. The 
specimen was in excellent condition, and | saved it out of my 
trammel whole, but some rough handling has since unfortunately 
crushed in the back part of the carapace. I had also Xanthus 
florida and rivulosa (in my opinion varieties of the same crab), and 
the Common Shore Crab. On the 22nd August we observed from 
the shore a shoal of some sort of fish passing in the very unusual 
direction of from east to west. It appeared to be broad and of 
about a half a mile in length. I afterwards learned from a boat 
which passed through it that it was a shoal of large-sized jelly-fish, 
probably Rhizostoma Cuvieri, the most common jelly-fish on our 
coast, and of which I took two or three specimens in the course of 
the month. 
Early in the month I took the Common Cuttle-fish, Hledone octo- 
pedia of Leach and Gosse, and Loligo piscutorum of Rymer Jones. 
After that I took the Bomb Cuttle, so called, I believe, from the 
resemblance of its sac to a bomb or mortar. This I consider to be 
Sepia officinalis, and to have by some writers been confounded 
with Eledone and Loligo, but it is quite distinct. Both have sepia- 
bags, and are consequently occasionally nuisances from their habits 
of “squirting ink,” but a clear distinction is that the backbone of 
the Cuttle-fish (which I regard as Hledone and Loligo) is horn-like 
and semitransparent, whilst that of the Bomb Cuttle (which I take 
to be Sepia officinalis), is the white opaque substance known to 
every one as the backbone of the Cuttle-fish. There are other 
exterior and clear distinctions to which I need not now refer.
