appearing as processes projecting outwards and forwards from the 

 sides of the hypapophysis (7i) not much above its ventral end. 

 The catapophyses (c), when the vertebra is viewed ventrally, appear 

 as the ends of two ridges diverging preaxiad from the postaxial 

 margin of the hypapopliysis (7t).

The Dorsal VeetebrjE. 



There are, in L. jlavopalUatus and P. erithacus, four of these 

 vertebrae distinct from the sacral mass. 



Theirs* dorsal vertebra in P. erithacus (figs. 13, 14, & 15) is very 

 like the last cervical, except that the postzygapophyses (ptz) are 

 slightly shorter and the transverse process (t) slightly more extended 

 antero-posteriorly. The hypapophyses (/ijj) have disappeared, but 

 the hinder end of the summit of the neural spine (n) slightly bifur- 

 cates and receives between its short processes the preaxiai summit 

 of the neiural spine behind it. The tubercular and capitular
