The 'fiddler' I placed in the large tank, where he rested content, and never again offered to escape--evidently the better of his experience. Not so his old friend, who still continued obstinate and miserable as ever. In his case I determined to see if a certain amount of sternness would not curb his haughty spirit. For two days I offered him no food, but punished him with repeated strokes on his back, morning and evening. This treatment was evidently unpleasant, for he scampered about with astonishing rapidity, and ever endeavoured to shelter himself under the granite centre-piece. When I thought he had been sufficiently chastised, I next endeavoured to coax him into contentment and better conduct. My good efforts were, however, unavailing. Every morning I placed before him a newly-opened mussel, but on no occasion did he touch a morsel. All day he continued struggling, as heretofore, to climb up the side of his chamber, trying by every means in his power to escape. This untameable disposition manifested itself for about a week, but at the end of that time, on looking into the vase, I saw the crab seated on the top of the stone, his body resting against the glass. I then took up a piece of meat and placed it before him. To my surprise he did not run away as usual. Having waited for some minutes, and looking upon his obstinacy as unpardonable, I tapped him with a little stick--still he never moved. A sudden thought flashed across my mind; I took him up in my hand, examined him, and quickly found that he was stiff and dead! * * * * * There is a little crab, _Porcellana longicornis_, or Minute Porcelain-Crab, frequently to be met with in certain localities. The peculiarity of this creature is the thickness and the great disproportionate length of his arms, as compared with the size of his pea-like body. He possesses a singular habit which I have not observed in any other crustaceans. He does not sit under a stone, for instance, but always lies beneath such object with his back upon the ground; so that when a boulder is turned over, these crabs are always found sitting upon it, whereas the shore-crabs, when the light of day is suddenly let in upon them, scamper off with all possible speed; or if any remain, it appears as if they had been pressed to death almost, by the weight of the stone upon their backs. The colour of _P. longicornis_ is that of prepared chocolate, shaded off to a warm red.
