This circumstance excited the greatest surprise and pleasure in the mind of the late Professor Fleming, in whose possession this famous Actinia then was. Up to this date (January 1860) there has been no fresh instance of fertility on the part of Granny, whose health, notwithstanding her great reproductive labours and advanced age, appears to be all that her warmest friends and admirers could desire. Nor does her digestive powers exhibit any signs of weakness or decay; on the contrary, that her appetite is still exquisitely keen, I had ample opportunity of judging. The half of a newly opened mussel being laid gently upon the outer row of tentacula, these organs were rapidly set in motion, and the devoted mollusc engulphed in the course of a few seconds. The colour of this interesting pet is pale brown. Its size, when fully expanded, no larger than a half-crown piece. It is not allowed to suffer any annoyance by being placed in companionship with the usual occupants of an aquarium, but dwells alone in a small tank, the water of which is changed regularly once a week. This being the plan adopted by the original owner of Granny, is the one still followed by Dr. M'Bain, whose anxiety is too great to allow him to pursue any other course, for fear of accident thereby occurring to his protegée. A portrait of Granny, drawn from nature, will be found on Plate 2. _A. troglodytes_[2] (cave-dweller) is a very common, but interesting object. The members of this species are especial favourites with the writer, from their great suitableness for the aquarium. They vary considerably in their appearance from each other. Some are red, violet, purple, or fawn colour; others exhibit a mixture of these tints, while not a few are almost entirely white. There are certain specimens which disclose tentacula, that in colour and character look, at a little distance, like a mass of eider-down spread out in a circular form. A better comparison, perhaps, presents itself in the smallest plumage of a bird beautifully stippled, and radiating from a centre. The centre is the mouth of the zoophyte, and is generally a light buff or yellow colour. From each corner, in certain specimens, there branches out a white horn that tapers to a very delicate point, and is oft times gracefully curled like an Ionic volute, or rather like the tendril of a vine. [2] The above mentioned Actinia is extremely abundant on the shores of the Frith of Forth. Sir J. Dalyell terms it _A. explorator_. Local amateur naturalists frequently reject the specific name of 'Troglodytes,' and adopt the more musical appellation of 'Daisy-Anemone.' Such error seems very pardonable, when we remember the close resemblance which the creature when expanded bears to the daisy of the field. In no single instance have I met with specimens of the true _A. bellis_ at the above named locality, nor do I think any have ever been found by previous naturalists.
