The vertebrac of the lumbal region are indicated by /. There are 
5 of them, consequently the 20 up to the 24 vertebra included. 
Their peculiarity is, that reduced ribs are completely coalesced with 
the transverse processes, consequently projecting parts are formed 
which are called processus laterales. 
The vertebrae of the sacral region are indicated by s. There are 
5 of them, consequentiy the 25% up to the 29" vertebra inclusive; 
they have processus laterales of the same morphological value as the 
lumbal vertebrae. But the sacral vertebrae have these processus fused 
together at the lateral extremities on either side of the body. This 
occasions the formation of the pars lateralis sacri, with which the 
girdle of the lower extremity articulates. The bodies of these verte- 
brae fuse likewise together at the formation of the os sacrum. 
The vertebrae of the caudal region are indicated by cd. There
