Each caudal vertebra bears one neural arch and one neural spine, and paired prezygopo- 

 physes, postzygopophyses, haemal prezygopophyses, and haemal postzygopophyses. The 

 prezygopophysis of the caudal vertebra is much smaller than that on precaudal vertebrae; 

 however, the postzygophysis of the caudal vertebrae is larger than that of the precaudal 

 vertebrae. 



Each transitional vertebra bears an incomplete haemal arch without haemal spine, and two 

 small free ribs. 



No morphological variation with phylogenetic significance is observed in the vertebrae 

 among the species of Phoxinus.
