For some time after the rest of the animal was completely dead from the effects of salt water or any other cause, this organ still retained its vitality.
I found no less than twelve different species of terrestrial Planariae in different parts of the southern hemisphere.

(2/3.

I have described and named these species in the "Annals of Natural History" volume 14 page 241.) Some specimens which I obtained at Van Dieman's Land, I kept alive for nearly two months, feeding them on rotten wood.

Having cut one of them transversely into two nearly equal parts, in the course of a fortnight both had the shape of perfect animals.

I had, however, so divided the body, that one of the halves contained both the inferior orifices, and the other, in consequence, none.
