Magilus is a genus of sea snails, marine gastropod mollusks in the family Muricidae, the murex snails or rock snails. This genus was brought by Michel (1988) into the separate family Magilidae together with Latiaxis

Description

Animal: The mantle-margin is thickened, the siphon very short. The foot is large, fleshy and oval. The operculum is ovate, the nucleus sublateral. Shell: The shell, when young, is spiral and, thin. When adult,it is white, solid, tubular and spiral for three or four whorls. The body whorl is prolonged into an irregular, straight or flexuous tube, solid posteriorly, and with a siphonal keel on the left side. This curious genus lives in coral, and the inordinate extension of the lips of the shell is to enable the animal to keep on a level with the surface of the coral as it continues to increase in size. As the shell grows, the tube behind is filled up with solid calcareous matter.
