bral, pedal and pleural ganglia and a single supraintestinal ganglion on the right side situated well 
posterior of the nerve ring. The eerebral and pedal eommissures are both elongate with well-sepa¬ 
rated respeetive ganglia. On the ventral side of the bueeal mass near the entranee of the esophagus 
are the bueeal ganglia whieh are immediately adjaeent to eaeh other. From the posterior end of the 
anterior nerve ring the right braneh of the viseeral loop extends posteriorly to the supraintestinal 
ganglion. The osphradial nerve emerges from supraintestinal ganglion. The two lateral branches of 
the visceral loop join posteriorly at the posterior ganglia. The left visceral loop enters the subin- 
testinal ganglion, while the right lateral nerve enters the visceral ganglion. The visceral ganglion is 
larger than the subintestinal ganglion. From the visceral ganglion is the genital nerve, which does 
not appear to have a distinct genital ganglion. 
Reproductive System (Fig. 4F, 5B-C): The arrangement of reproductive organs is essentially 
monaulic (as discussed by Gosliner 1994) but with a single branch of the hermaphroditic duct to
