Descriptions

This species is amphibious, and is usually found in or near water. Numerous sub-species have been described; and it seems to vary a great deal. One specimen from Douglas Head, Isle of Man, agreed almost exactly with the var. bernensis (Ribauc.). The male pores were on the 12th segment, the clitellum occupied segments 22-25, and the tubercula were on segments 22 - 1/2 25. It was probably only a mutational form, as numerous specimens from the same locality were quite normal. (ref. ID; 1928)
