Diagram illustrating the organization of the (a) competent larval (11-12 days after oviposition) and (b) 1-day postmetamorphic (13-15 days after oviposition) CNS of Berghia vumicicumis The anterior portion of the CNS is positioned toward the top of the page. In the 1-day postmetamorphic juvenile the cerebral and pleural ganglia are fused, and the visceral ganglion is being incorporated into the left cere- bropleural ganglion.

Diagram illustrating the organization of the (a) competent larval (11-12 days after oviposition) and (b) 1-day postmetamorphic (13-15 days after oviposition) CNS of Berghia vumicicumis The anterior portion of the CNS is positioned toward the top of the page. In the 1-day postmetamorphic juvenile the cerebral and pleural ganglia are fused, and the visceral ganglion is being incorporated into the left cere- bropleural ganglion. The dotted lines indicate portions of the cerebro- buccal connectives (a) and the pleurovisceral loop (b) that are assumed to be present, but could not be traced in 1-^m sections. The pedal com- missure has been separated at the points indicated by the jagged lines. BG = right buccal ganglion; C = left cerebral ganglion: CC = cerebral com- missure; CP = cerebropedal connective; CPL = right cerebropleural gan- glion; C-PL = right cerebropleural connective: O = optic ganglion; P = pedal ganglion; PL = left pleural ganglion; PLV = portion of the pleurovisceral loop: PN = pedal nerve; Rh = rhinophoral ganglion; RhN = rhinophoral nerve; Vi = visceral ganglion. veliger ofAeolidiella aldcri. Just posterior to these putative cerebral ganglia, that author identified the left and right parietal ganglia. These ganglia were connected by a parie- talvisceral loop that, moving from left to right, included infraintestinal, abdominal, and supraintestinal ganglia. The relative location of the pleural ganglia we have de- scribed in B. vernicicornis is the same as the parietal gan- glia described by Tardy (1970, 1974) in larvae of Aeoli- i/ielln aldcri. Presumably, in B. vernicicornis, the abdom- inal and the supra- and infraintestinal ganglion described by Tardy (1970, 1974) in Aeolidiella alderi are either fused with the visceral ganglion or with the pleural ganglia. Other studies have reviewed the changes that occur in the opisthobranch central nervous system durin
