On an occipital vermian fossa and cerebellar vermian eminence. 
By G. F. Rogers, M.D., Gonville and Cams College. (Com-

[Read 25 February 1907.] 
A median occipital fossa 14 mm. x 35 mm. in the shape of 
a gutter was shown with a series of varieties ranging from a small 
triangular flattening at the base of the occipital crest, through 
triangular fossae of increasing size up to the specimen noted above. 
The cerebellum belonging to the specimen was also demonstrated 
to possess an enlarged median lobe, the lateral lobes being 
separated by a distance corresponding to the breadth of the median 
fossa. A falx cerebelli was seen on each lip of the groove. 
Specimens of anthropoid skulls were shown demonstrating the 
existence of this groove in the gibbon only. A discussion was 
initiated as to its reputed more frequent appearance in the skulls 
of criminals, epileptics and lunatics.
