They show the continuance of the metapophyses after the true zygapophyses and their

 eighth, ninth and tenth caudals, and disappears upon the eleventh. 



2027. The left scapula. 



The long and slender acromion has been broken off.

It is perforated between the condyles. 



2029. The left radius. 2030. The left ulna.

 inner side of the base of the second metatarsal. There is a supplemental ossicle on the inner 

 side of the joint, between the astragalus and scaphoides.
