Sagittal section of the head of a newly hatched embryo (Stage XV), passing laterad of the median plane and intersecting the right half of the brain (Br), the circumoesophageal commissure (OeCom) and the suboesophageal ganglion (SoeGng), x 337. nerve or nervus recurrens, and a pair of ganglion lying against the sides of the posterior region of the oesophagus, the pharyngeal ganglia. To these may be added, for the sake of convenience, the so-called ganglia or corpora allata of Heymons, which in fact are probably not ganglia at all, according to Heymon's own state- ment (1897), (Figs. 39 and 42, Cor All). The frontal ganglion (Figs. 39, 40 and 45, FtGng) is a large and conspicuous pyriform ganglion with its blunt end directed ceph- alad, lying in the median plane at the base of the lab rum and just above the oesophagus. It consists of a compact mass of ganglion cells surrounding a core of nerve fibres. From its anterior end nerve fibres, accompanied by a few scattered ganglion cells, run to the tip of the labrum. At its posterior end the frontal ganglion becomes continuous with the stomatogastric or recurrent nerve (Figs. 41, 42 and 45, StgNv) which runs backward in the median.
