118 POST-PLEIOCENE FOSSILS. 



The remains, consisting of teeth and vertebrae, though presenting no character of import- 

 ance by which to distinguish them from the recent Spermaceti Whale, nevertheless, are 

 supposed to indicate a different species on account of their great age. A tooth of the 

 Physeter antiquus, being the best of several specimens found in the Ashley Post-Pleiocene 

 beds, is represented in figure 8 of Plate XXIV. It is of small size compared with the 

 large ones frequently seen from the recent species, and although it is as large as any of 

 the fossils we have had the opportunity of inspecting, the difference in size may depend on 

 the difference of age of the individuals. Fig. 9, of the same plate, represents a tooth of 

 quite perfect and recent appearance, discovered in an excavation in the vicinity of 

 Charleston, which Prof. Holmes supposes to belong to the same species as the fossils of 

 the Ashley beds.

Some small fragments of jaws, with teeth, of a species of Lepidosteus, have been found 

 among the Ashley river fossils. One of these specimens is represented, at a, figure 1, 

 Plate XXV, in position in its relation with the skull of the existing Lepidosteus bison.
