CYCLOBRANCHIATA. 
Dr. Ed. Brandt has examined and compared the nervous 
systems of Patella vulgata and Chiton {Acanthochites) fascicu- 
laris. In the former there are three pairs of ganglia communi- 
cating with one another hy commissures, and forming the cen- 
tral parts of the nervous system, viz. the ganglia cerebralia, the 
ganglia visceralia sive hranchialia, and the ganglia pedalia. In 
Chiton the branchial and pedal ganglia are united on each side 
into one (pedobranchiale), as is proved by the nerves, and 
the cerebralia are absent altogether, as the animal has not 
either eyes or tentacles, which organs are provided in other 
mollusks with nerves coming from the ganglion cerebrale; but 
there is a very strong anterior commissure between the two 
ganglia pedobranchialia, giving origin to labial and pharyngeal 
nerves, and this commissure has been regarded as a cerebral 
ganglion by Middendorff. The branchial nerve is very strong
