Represented by three vertebras from the posterior part of 

 the dorsal region. The centra are subcircular and have deep 

 articular cones, with their bottoms above the centre, and 

 minutely perforate for the notochord. The centra are com- 

 paratively quite long, and have prominent projecting rims, 

 and are truncate beneath. The facets for the neurapophyses 

 are long, and are separated into two parts for the contiguous 

 arches. The diapophyses are short and stout.
