There are 24 vertebrae between the skull and the sacrum, of which the last eight bear 

 moveable ribs : of these the last six pairs are united to the sternum by hsemapophyses : a 

 ninth pair of ribs is attached to the sacrum and also to the sternum. Three dorsal vertebrae 

 have coalesced, and three remain free between these and the sacrum : the sternum is very 

 long and narrow, without posterior notches or holes : the coracoid sends off from its inner and 

 anterior border a long thin ridge, which forms an angle at its upper part. The procnemial 

 and ectocnemial ridges of the tibia extend well outwards, but their base is short.
