MORPHOLOGY OF THE CEREBRAL CONVOLUTIONS. 269 



XVI. FlSSUKA CALLOSO-MARGINALIS. 



Ecker : sulcus calloso-marginalis. 



Pansch : sulcus calloso-marginalis and sulcus medialis fronto-parietalis. 



Broca : scissure sous frontale. 



Turner : calloso-marginal fissure. 



Gratiolet : grand sillon du lobe fronto-parietale. 



Ferrier, Huxley, Richet : sulcus calloso-marginalis. 



Lussana e Lemoigne : scissura crocciata, scissura parietale interna. 



XVII. FlSSURA OCCIPITALIS TRANSVERSUS. 



Generally portrayed as a ramus at the lower end of the fissura parietalis. It 

 is important as a means of bounding Gratiolet's plis de passage on the 

 occipital extremity. 



XVIII. FlSSURA ORBITALIS. 



Ecker : sulcus orbitalis. 



Ferrier : orbital sulcus. 



Fowler : orbital sulcus. 



Henle : indicated. 



Gratiolet : sillon de la face orbitaire du lobe frontal. 



Lussana e Lemoigne : solco orbitale. 



XIX. FlSSURA OCCIPITALIS LONGITUDINALIS INFERIOR. Ecker. 

 XX. FlSSURA PAR ACENTRALIS. 



Betz : transverse furrow of the paracentral lobule.

 A. External Surface. 



I. Gyrus frontalis superior. 



Pansch : gyrus frontalis superior. 



Ecker : erste Stirnwindungsgruppe. 



Henle : oberster gyrus frontalis. 



Huxley : supero-frontal gyrus. 



Broca : premiere circonvolution frontale. 



Turner : superior frontal gyrus. 



Huguenin : dritte Stirnwindung. 



Valentin : gyrus adplicatus anterior. 



Lussana e Lemoigne : circonvoluzione parietal anteriore. 



Ferrier : superior frontal convolution. 



Fowler, Charcot : first frontal convolution. 



Richet : premiere circonvolution frontale. 



Gratiolet : premiere circonvolution frontale.
