Abstract
THE normal colour of the head, mantle, and footsole of the pond-snail Limnæa peregra is a yellowish grey of variable intensity which is clearly visible through the horn colour of the shell. The eyes are black. During the course of our experiments with the sinistral form of this snail (Jour. of Genetics, 15, 113) a new mutant has appeared in which the head, mantle, and footsole are yellow and the body has no melanin anywhere. The eyes are visible as brownish specks, contrasting with the deep black of the normal specimens. The appearance is presumably a diffraction effect of the lens, for microscopically there is in young specimens no retinal pigment, though in snails that have grown up and bred a little brownblack pigment can be seen in the retina. We call this mutant albino-body.
