On the assumption that great length of the chord of the pars glabellaris 
is a primitive feature, the figures in this table are arranged in an ascending 
scale from the nearest anthropoid to the maximum, and thereafter in a 
descending scale. This table is also omitted from the final results obtained 
in Mr Cross’s paper, and for the same reasons that Table I. is omitted.
