The jugal is large, and is not divided into two pieces as it is in the Ziphioids.
The jugal (fig. 11, 17) lies above the maxilla and overlaps it in front.
In the skull (fig. 83) the postorbital processes of the frontal and jugal almost or quite meet.
The jugal process meets also a down-growth from the postfrontal.
Processes from the jugal and frontal in living forms never meet and enclose the orbit, but the zygomatic arch is always complete.
The lachrymal may either be united to the jugal or may be large and distinct.
In poisonous snakes the place of the jugal is taken by the zygomatic ligament which connects the quadrate and maxillae.
The outer row is formed of the prmaxilla, maxilla, jugal, and very often quadratojugal.
The lachrymal and jugal form a considerable part of the side of the face; and the orbit though small is complete and prominent.
In Cynognathus the postorbital is fused with the jugal, and the supratemporal with the squamosal, forming apparently one bone.
