Living animal approximately 15 mm in length. Body white, with low tubercles on the notum; oval and elongated, with three marginal bands on the mantle edge. There is an outermost blue band followed by a deep red submarginal band and a yellow inner submarginal band. Brownish or orange dorsal spotting may be present over the surface of the mantle. In all cases the rhinophores are translucent reddish brown with white edges on the lamellae. The same pigment extends below the rhinophore club onto the stalks of the rhinophores. Rhinophore lamellae number 12-17. Gill branches reddish brown with white lines on the rachis. Nine or ten unipinnate gill branches held erectly when the gill is fully extended. This species exhibits four distinct morphotypes in addition to the unvarying elements described above. Morphotype A (Fig.

). The thick, tubular ampulla narrows into a diverging short oviduct and long vas deferens. The proximal prostatic portion of the vas deferens is narrow and convoluted, then transitions into an equally thin muscular ejaculatory portion. The narrow ejaculatory portion elongates into a wider section and again narrows prior to entering the short penial bulb, which joins with the distal end of the vagina. The vagina is short and moderately wide. It terminates at the junction of the large, spherical bursa copulatrix, the curved, pyriform receptaculum seminis, and the uterine duct. The long narrow uterine duct emerges from junction of the vagina, bursa copulatrix, and the receptaculum seminis and enters into the female gland mass. The female gland mass has small albumen and membrane glands and a large mucous gland.
