Greatest vertical width of the zygoma- 

 arch behind the orbit - i of an inch. 



Observations. The occipital crest is but little ele- 

 vated on the sides, and not at all on its vertex, at 

 which point it is the most promineut backward in the 

 form of a very obtuse angle : it is not undulated on 

 the sides. The zygomatic arches, in consequence 

 of their breadth, have their inferior edge nearly in a 

 line with the crowns of the two series of upper mo- 

 lares, and terminate in a prominent angle pointing 

 backwards.
