based upon the teeth and otolites, the latter determined by 

 Mr. Higgins.

Sharks' teeth (of several genera, Otodus, Lamna, Oxyrhina, 

 «&c.) are very abundant in the lower division of the Red Crag, 

 but are scarce in the Coralline Crag, and are generally con- 

 sidered to be derived from the abrasion of older deposits, 

 chiefly London Clay. I venture to put in a word in favour of 

 Carcharodon megalodon, Ag., being a native of the Red-Crag 

 sea. Its distribution in Miocene times being world-wide, the 

 British-Museum collection containing examples from Malta, 

 Bordeaux, Maryland, Aspinwall (Panama), and New Zealand, 

 it is likely to have lived on for some little time after the Mio- 

 cene epoch had passed away. 



The only sharks' teeth that I have seen in the Coralline 

 Crag are a species of Lamna (1 sp.) and one of Oxyrhina 

 (3 sp.), closely resembling 0. xiphodon, Ag., a fossil of the 

 French and Belgian Miocenes. I have no doubt of the Oxy- 

 rhina being an inhabitant of the Coralline-Crag sea. A few 

 vertebrae resembling the figures given by Agassiz of Platax 

 Woodwardi also occur.
