is cut in two :—and Mrs. Wyatt has only met with it once. This
is, however, not to be wondered at, if we consider the extremely
local nature of many species of Ectocarpus, and that Salcombe,
the habitat of our novelty, is a considerable distance from the
discoverer’s ordinary abode. In appearance E. fenestratus is
not unlike many specimens of E. siliculosus, but the form of the
silicule is very different; and in this character there is a much
nearer approach to E. tomentoms, a species, which in all other
respects, is widely different from E. fenestratus.
