Nasal width, the distance between the anterior lateral spines 

 of the nasal bones (pi. 35, fig. 1, B) ranges in this series of 

 skulls from 37 to 13 mm, the greatest distance being almost 

 three times the smallest. Text-figure 6 indicates only a slight 

 and irregular accord between these nasal widths and the 

 sequence of zygomatic widths.
