I think that the word "dolicocefalo" (and also some similar words ) are related to Cesare Lombroso (about 1880?), who was thinking that it is possible to predict the behaviour (criminal or not) of someone from the shape of his skull ( and - I imagine- from the size of its brain). So he was classifying people in several classes, according to the kind of shape...
Do you remember "Frankenstein junior", when there is a collection of brains... and Marty Feldman takes the one with the label "ab normal"?
