). Paired cerebral ganglia (ce) elliptical, about twice as long as wide; cerebral commissure short, with about half width and length of each ganglion. Each cerebral ganglion of about 1/4 width of local oral tube. Pair of optical ganglia slightly smaller than cerebral ganglia, located close to these, connected to antero-median side. Tentacular nerves connected more internally than connection of optical ganglia. Pair of pedal-pleural ganglia (pp) forming single mass located opposite cerebral ganglia, and of about the same size as cerebral ganglia. No differentiable ganglion detectable. Several pairs of nerves originate from these ganglia towards anterior. Pair of cerebro-pedal and cerebro-pleural connectives (cn) similar-sized, about as long as cerebral ganglia. Pair of possible odontophore ganglia (of) fused with each other, located a distance equivalent to nerve ring length away from pedal ganglia, connected with them by pair of connectives, inserted in median-ventral side of each ganglion. Pair of buccal ganglia located in antero-dorsal region of buccal mass, close to esophageal origin and salivary insertion (

Visceral ganglion located in posterior level of columellar muscle, with ~1/2 size of cerebral ganglion; connective with nerve ring running towards anterior ~1/3 whorl, passing just between penis and vagina.
