specimen, there is no pneumatic foramen between the pre- 

 zygapophysis and the rib-facet. 



32177 i. A nearly similar, but more imperfect specimen. 



32154 a". A smaller entii-e first dorsal vertebra. 



32154 b. A second dorsal vertebra, wanting the neural spine, and 



probably associated with No. 32154 a. In this vertebra 

 the transverse process is longer, the rib-facet larger, and 

 the lateral borders of the anterior face of the centrum 

 are situated more forward than in the first dorsal. 



32155 a. The entire second dorsal vertebra of a smaller bird. 



32155 b. A slill smaller second dorsal vertebra. 



32156 a. A nearly similar second dorsal vertebra. 



32154 c. A nearly similar specimen. 



32155 C. A somewhat larger second dorsal vertebra. 



32157 a. A nearly similar second dorsal vertebra. 



32154 d. A large second dorsal vertebra. The rib-facet is abnor- 

 mally small, but the forward projection of the lateral 

 borders of the anterior surface of the centrum shows that 

 the specimen is the second and not the first of the series. 



32156 b. The third dorsal vertebra of a full-sized bird. The lateral 



borders of the anterior face of the centrum project con- 

 siderably more forward than the prezjgapophyses, the 

 posterior face of the centrum is extremely narrow and 

 tall, there is still a continuous hsemal spine, but no anterior 

 pneumatic foramen. 



32156 c. A slightly smaller third dorsal vertebra. The haemal 



spine, which is imperfect in the preceding specimen, is 

 here nearly entire. 



32157 b. A still smaller third dorsal vertebra. The anterior arti- 



cular surface of the centrum is absolutely wider than in 

 the preceding specimen, and thus probably indicates 

 specific distinctness. 



32159 a. A third dorsal vertebra agreeing closely with the pre- 

 ceding specimen in size, but with a narrower anterior 

 face to the centrum.
