whose original had escaped. This renovated creature was delineated 

 the day after exuviation. — Plate XLI. fig. 3. It died in April. 



The history of the assailant of the mutilated animal^ which had 

 committed such injuries, is afterwards given in detail. 



Two small specimens having been together, I observed, on Oc- 

 tober 30, that the larger, which was nearly white, had mutilated its lesser 

 companion, not only of both claws, but of sis limbs in addition, leaving 

 only the first on the right side, and the second on the left, Plate XLI. 

 fig. 1. Thus, eight of the ten external organs were deficient, while the 

 remaining two seemed to be injured. Nevertheless, the animal fed 

 when offered a fragment of mussel, though incapable of turnmg itself if 

 supine. Three days afterwards it was quite voracious. 



I preserved this mangled creature very carefuUy, contemplating the 

 solution of several points still enigmatical, should it survive exuviation. 

 Matters advanced propitiously enough for some time ; the animal fed 

 on the 23d of December, but it died during the night of the 24th. 



Yet this did not seem in consequence of its wounds, from the evil 

 effects of which it had certainly recovered. But the period of exuvia- 

 tion was at hand, and the apparent immaturity of certain parts prevent- 

 ing then' hberation, while others were completely ready, and actually 

 protruding for escape, — the death of the creature ensued. 



What I could see on this occasion, led me to conclude that aU the 

 limbs of the new animal, while in the original shell, lay folded across its 

 breast. 



It was of some consequence to determine the precise fact, not only 

 as elucidating the truth, but as confuthig the prevalent opinion of new 

 limbs shooting from the old in one case, and being derived from so many 

 sheaths in another. I have abeady shewn the improbability of papUlas 

 originating from mutilated stumps to announce reproduction. In such 

 enquiries, however, there is scarcely any du-ect means of verification to 

 be adopted, farther than patiently following the course of Nature, and 

 awaiting the issue of observation. 



Thus, the assailant of the preceding specimen, that had unluckily 

 perished, had been preserved for some time previously. It was then
