70 mm.- 100 mm. long whitish In colour creamy or reddish to yellowish grey with numerous black dots . The mantle is 40% of body length (preserved specimens) . The mantle is granular with a deep but not conspicuous horseshoe-shaped groove with black streaks. The breathing pore has a pale rim. The keel is yellowish to white.The sole is cream.
The penis and epiphallus form a single long cylindrical organ: penis with a swelling anteriorly, inside with a richly ornamented papilla, epiphallus obviously longer than penis. ,The vas deferens opens symmetrically, the spermatheca is elongate with a sharp pointed end, its duct slightly shorter and with a swelling half-way.The vagina is not much wider than the oviduct, accessory glands are compact duct-like canals, surrounding and opening to the anterior end of the vagina, The atrium is short.(Francisco Welter Schultes)
