THE CRETACEOUS SYSTEM 323 



Africa and the north of Madagascar there are Neo- 

 comian beds with a few forms identical or closely allied 

 to Uitenhage species ; and in South America, in Bolivia, 

 Chili, and the Argentine, there are species of Trigonia 

 very like Uitenhage forms. 



It is probable that the whole of the Uitenhage for- 

 mation falls within the Neocomian series, and the fact 

 that no definite subdivisions based on the distribution 

 of the fossils have been found corroborates the conclu- 

 sion, drawn from the lithological characters of the rock, 

 that the formation was deposited comparatively rapidly. 



The following is a complete list 1 of the invertebrate 

 fossils from the Uitenhage series : 



Anthozoa 



Isastraea richardsoni var. antipodum, Tate. 

 Thamnastraea, sp. 



Echinodermata 



Cidaris pustulifera, Tate. 

 Annelida 



Serpula cf. concava, J. Sow. 

 . ,, pinchiniana, Tate. 

 Polyzoa 



Berenicea antipodum, Tate.
