Anterior part of the specimen towards the right, dorsal surface to the top and ventral surface to the bottom (scale bar 400 mm, BMNH catalogue number 1998.2.9.1); 5, sagittal section illustrating one of the two vasa deferentia (D) receiving the openings of some testes on the way to the penis papilla (T), the well developed layer of longitudinal parenchymal muscles (M), and the pharynx (H). Anterior part of the specimen to the bottom, dorsal surface to the right and ventral surface to the left (scale bar 400 mm, BMNH catalogue number 1998.2.9.1); 6, sagittal section illustrating one of the two enlargements of the vasa deferentia (D) at the base of the penis papilla; pharynx (H).
