^' It must be remarked that the clctenuiiiation of isolated rostra is not always 

 certain; there is no possibility of distinguishing those of F. aniiqiiorvm horn. 

 those of P. ferrotteti. 



t As in almost every other species of this genus, the size and length of these 

 teeth is variable ; they are sometimes as small as in the " microdoii" form of P. 

 jjcrrottcfi, and scmetimes as long as in the " megalodon " form of P.^ectinaius.
