Distribution of the dent or depression in the foreliead is here sliown in grajihic form. Squares 

 represent males and circles females; black symbols designate individuals who show the 

 trait in question; x implies unknown; the abbreviation d.hif. means "died in infancy." 

 Some doubt exists as to whether individual No. 7 in generation II showed the trait or 

 not. (Fig. 7.)
