noctiluca

Of the insects thus singularly provided, the common Glow-worm (Lampyris noctiluca) is the most familiar instance.

Probably the Noctiluca is not rivalled in this respect even by miscroscopic unicellular alg which compose the "red snow."

Both in its nature and immature forms, Lampyris noctiluca plays a useful part in the economy of Nature.

I do not see how they could be the L. noctiluca, as he states.

Ray first pointed out this fact with respect to L. noctiluca.
