this being specially the case with those to which, on account of the remarkable habit, the popular name of vegetable sheep has been applied. It is quite possible that several species are confounded under R. eximia and allied forms. All the New Zealand species are endemic, and in addition there are one or two found in Australia and Tasmania.
