Lobe bordering pericardium on left side of kidney, comprising hypertrophied nephridial gland (ng). Afferent renal vessel entering kidney floor anteriorly, just behind reno-pericardial canal (rpc). Afferent renal vessel splitting into two large branches, one extending antero-dorsally along front wall of kidney and supplying right lobe, second branch extending postero-dorsally. Postero-dorsal branch supplying both right and central lobes.
