Descriptor : Interorbital constriction

The interorbital constriction corresponds to the ratio between the post-orbital constriction and the "frontal constriction" (just anterior to the postorbital process, vertical to the lacrymal foramen). The value 0.12 is the mean of the standard deviation for the means concerning the measures of the interorbital constriction from all the taxa.
