. Fig. 1. Anne lid ANNELIDS (Worm Tubes) These organisms can be readily recognized by their hard tubular shells (figs. 1 and 13), each of which houses a living worm. Sometimes the whole shell adheres firmly to the hull, but it may rise from the surface and stand out at a sharp angle. These tubes range in length from a fraction of an inch to several inches, and may form a large proportion of the fouling, especial- ly on ships which have been stationed in the Ha- waiian Islands or the southern Pacific. Some of the commonest forms have the scientific name of Hydroides» This should not be confused
