cephalic ganglia1835–6
archicerebrum1881
1881 E. R. Lankester Stud. Apus, etc. 32 We distinguish the original ganglion pair of the præstomial region as the archi-cerebrum—it is well to designate by a distinct term the composite ganglion, which may result from the fusion with it of other ganglia—it may be called a syncerebrum.
1882 Athenæum 14 Jan. 60/2 In Apus the two pairs of antennæ are not supplied by nerves from the archi~cerebrum.
