Internally, central raphe endings straight, filiform, with pronounced central nodule. Distal raphe endings terminate in simple helictoglossae, slightly bent away from centre. Areolae openings occluded by simple volae, which coalesce with neighboring volae to form a chain-like structure within a stria. Cingulum composed of two slit narrow bands regularly perforated by fine pores.
