CHAPTER XII. FOSSIL FISHES, AMPHIBIANS, REPTILES, BIRDS, AND MAMMALS. =Vertebrates.--= The above-named classes of animals are distinguished from those previously dealt with, by the presence of a vertebral column. The vertebral axis may be either cartilaginous as in some fishes, or bony as in the greater number of animals belonging to this sub-kingdom. =Chordata.--=
