X I have endeavoured to keep apart the specimens found in each of the beds 

 belonging to this group. But some of the species occur in all of them ; those 

 especially of No. 4 and 5 a are very nearly the same. 



§ There is some difficulty in defining this species from the mere fragment figured 

 by Parkinson : the specimens have been identified by M. d'Orbigny with his T. rudis, 

 of which the T. nodosa, Sow., is probably but a variety ; but it is certainly distinct 

 from T. spectabilis, Sow., which is considered identical by M. d'Orbigny. In com- 

 paring the Isle of Wight specimens with the true T. Dcedalea of Blackdown, there 

 is much less difference between them, than between the same Blackdown species 

 and the T. Dadalea figured in the ' Palaeontologie Franpaise.' — M.
