At about one-third of the length of the body from its front ,,, end, in segments 32-37 inclusive, a glandular thickening of the epider- mis lies athwart the back like a saddle and is often mistaken for the scar of a wound. This is known as the clitellum. The skin of the worm is brownish above and paler below; it is covered with a fine, tough, iridescent cuticle secreted by the underlying cells.
