In the Crickets (Gryllidas), as in the Crustacea and the Cockroach, the infra-oesophageal are separated from the supra- oesophageal ganglia by long nerve-like crura, the oesophageal KiG. 57.—An oblique section from above and behind, downwards and forwards, through the supra-oesophageal centres of Iht same insect: <•/, ci, the calices; c, procerebral lobes ; /, corpus fungiforme. The ventricular cavity is seen in front, between the bundles of fibres which support the nulimenlary procerebral lobes. The great cells behind the ventricle and between the inner calices arc the cells of the pyramidal ganglion. connectives, but there is a distinct advance towards the type exhibited by the more specialised Insecta. This is especially seen in the reduction of the proportionate size of the corpora 30—2
