In adult specimens the place at which a process takes its originis generally indicated on the surface of the ventricular floor by a more or less well marked groove(text fig. 1). The size andform of the groove corre-spond in some degree tothe size and compactnessof the neuroglia is: when the processis compact and slender thesurface groove is usuallysharply cut, and when theprocess is broader and lesscompact the surface de-pression is shallower andmore rounded out.
