Reproductive system
: Penis usually short, epiphallus long, retractor penis inserting at boundary between penis and epiphallus, vas deferens of specific length opening into posterior end of epiphallus, vagina accessory glands (usually more than one) of specific shapes, connected by ducts to the vagina or to the point where the vagina enters the atrium. Atrium small, tubular, no stimulator inside. Spermatheca of specific size, spermatheca duct longer or shorter than spermatheca.

Description
Slug body elongate up to 100 mm, usually with almost parallel sides, posterior part abruptly narrowed, keel usually low, restricted to last section of dorsum in some species, reaching mantleMantle (mollusc)
The mantle is a significant part of the anatomy of molluscs: it is the dorsal body wall which covers the visceral mass and usually protrudes in the form of flaps well beyond the visceral mass itself.In many, but by no means all, species of molluscs, the epidermis of the mantle secretes...
