On a single spray of ruddy Gorgonia several of these commensal molluscs may occur in various stages of development--the smaller no bigger than the wing of a fly and almost as frail, the larger three and four inches long, and each whatsoever its proportions securely budded on and growing from a spur, while frequently the valves of the large are bossed with limpets and other encumbrances.
