The character of Calotis was formed, but not published about fifteen years ago, from C. dentex, a species first observed by Mr. Brown himself in New Holland, where it is not uncommon in the neighbourhood of Port Jackson. The present has been since found, during an expedition into the interior of the above country, growing on the banks of the River Lachlan in 1817, by Mr. Allan Cunningham, who is commended by Mr. Brown as " an indefatigable collector and acute observer."
