condyle of the lower jaw and is joined under the orbit to 
the maxilla by a small jugal (or malar). This bony bar is 
called the zygomatic arch. 
The mandible or lower. jaw is in one piece or ramus on 
each side. It has a condyle for articulation with the skull, 
an angde at its posterior end and a coronoid process produced 
upwards in front of the condyle. 
The Ayoid consists of a central piece and two pairs of 
cornua, as in the frog.

Lastly, in the middle ear is a chain of three ear-ossicles, 
the malleus, incus and stapes. The malleus is attached to 
the inner surface of the tympanum and the stapes to the 
Jenestra ovalts of the inner ear. 
The vertebral column consists of cervical, thoracic, lumbar, 
sacral and caudal vertebre. 
There are seven cervicals, as in nearly all mammals. The 
first is the aé/as with two lateral wing-like cervical ribs, a
