Extract

So far as regards number of individuals, and their size, this is one of the largest collections of Ascidians brought back in recent years from Antarctic seas. It contains almost exactly the same number of species of Ascidiacea (Ascidiæ Simplices + Ascidiæ Compositæ) as the Discovery collection—viz. fifteen or sixteen—but whereas in the latter collection nearly all the species were represented by single specimens, in the Scotia collection most species can show long series of individuals—in all there are about two hundred specimens, as against the thirty-three brought home by the Discovery.
