From great unwillingness to delete the nomenclature of our older authors, and because Leach appears to have had no precise idea of his N. margaritacea, and the name has been variously applied, I gladly venture to affix to this species a Linnsean name, more appropriate than Leach's, and which nothing in the Linnsean de- scription contra-indicates. {a) Falmouth. {b) Falmouth. 5.

It is distin- guished by its yellowish-white colour (when alive) with a strong pearly lustre, and by its prominent feet armed with black spines, which are quite visible in their sheaths. The head is streaked, more or less, with brown on the sides; and the anterior portion of the body is tinted with the same colour. The eyes are large and ap
