 The transverse process of the sixth cervical is pierced first by the vertebral artery : 7 ver- 

 tebrae are cervical, 13 are dorsal, 6 lumbar, 2 sacral, and 25 caudal : the fourth to the seventh 

 of these last have hirmapophyses.

 detached, and is very minute. In the lower jaw p 4 is the only fully developed premolar : 

 there are the sockets of two radimental premolars, besides that of the minute canine, on the 

 right side.
