In none of these cases was there any evidence that the structural variations had resulted from injury. In the period over which these individ- uals were obtained there were also collected about 1,000 normal specimens of the same species. These figures give, however, no precise idea of the relative frequency of "rhinophore" variation, because a larger number of specimens had been collected in previous years without any occurrence of these variations being observed.
