posterior transverse processes, metapophyses, neural arch and 

 neural spine, together with hypapophysial processes or arches 

 (chevron bones), may be present in man's own class. In Fishes 

 the hypapophysial parts may be very largely developed, as, 

 e.g., in the Flat-fishes. In Tailed-Batrachians, the anterior

coccygeal vertebras (e.g. in Menobranchus] may be furnished 

 with true ribs, supported by both tubercular and capitular 

 transverse processes, in addition to articular, neural, and 

 hypapophysial parts.

The downwardly tapering condition of the coccygeal verte- 

 bras which exists in man is the general condition of such 

 parts ; but sometimes, as in the little Armadillo Chlamy- 

 dophorus, the transverse processes increase in size instead of 

 decreasing in that direction.
