neighbouring estuary of the Dee, the former is common, 

 as usual. 



With ordinary attention the pretty Beadlet will attain 

 a good old age in captivity. A veteran, whose portrait is 

 given by Sir John Dalyell, had lived in his possession 

 twenty years (in 1848), and was judged to be not less 

 than seven years old when he obtained it. At Sir John's 

 death the specimen passed into the hands of Professor 

 Fleming, and it was not many months ago that I heard 

 of it as still surviving. If it is alive now, it must be 

 approaching forty years old. This individual was the 

 prolific parent of 334 children. A second specimen had 

 lived about fourteen years under the worthy baronet's 

 care. 



The species is generally viviparous, producing abun- 

 dantly ; but sometimes it gives birth to ciliated, shapeless 

 embryos, on which tentacles appear in about ten days. 

 Copious details of high interest on the embryology and 

 general economy of this Anemone are furnished in the 

 magnificent volumes of the eminent Scottish naturalist. 



It is superfluous to give a list of habitats for this 

 species: since it occurs all round the coasts of England, 

 Wales, Scotland, and Ireland, wherever there is rock 

 enough to afford it standing ground. 



The Actinia Cari of Delia Chiaje (the A. concentrica 

 of Risso) appears to be a second species of the genus ; at 

 least in none of the recognised varieties of ours do we 

 perceive an approach to the pattern of colouring, — a series 

 of concentric zones or bands, — by which that is marked.
