Fig. 1. The central nervous system in dorsal view. The connective-tissue capsules and sheaths — 
of the ganglia and nerves have been dissected away, and are not represented in the drawing. The — 
cerebral ganglia are shown in the upper part of the Plate, their nerves being indicated on the right . 
side only by c1, ¢2, ete., the homologous nerves of the left side being symmetrically located and 
easily ceeeentionisles c-b con, the cerebro-buccal connectives passing to the buccal ganglia (Plate 3, 
fig. 3); c-pcon, and c-pl. con, the cerebro-pedal and cerebro-pleural connectives, joining the cerebral _ 
to the pedal and pleural ganglia respectively, and shown on the lower half of the plate. Owing to — 
the great length of these connectives their full extent is not represented, the interruption being indi- 
cated by the dotted portions. The pedal nerves are numbered serially in the order of their appearance - 
from the ganglia, from in front backward; pl. 1 and pl. 2, the first and second nerves from the pleural 
ganglia; pl-par.c, the pleuro-parietal connective of the right side; pl-v. con, the pleuro-visceral con- 
nective on the left. X 10.
