Figure 14. Paphies elongata. An interior view of the fused ventral mantle margin posterior to the pedal gape and showing the rejectory tract. This figure also illustrates the posterior adductor muscle and the visceral ganglia beneath it. AN, anus; AVG, accessory visceral ganglia; FIMF(2), fused inner mantle folds (outer component); IMF(1), inner mantle fold (inner component); IS, inhalant siphon; PA (1), posterior adductor muscle (anterior component); PA(2), posterior adductor muscle (posterior component); PGA, pedal gape; R, rectum; RT, rejectory tract; SN, siphonal nerve; SRM, siphonal retractor muscles; VG, visceral ganglia; VG-AVG-CONN, visceral ganglia-accessory visceral ganglia connective.
