Amougst the Foraminifera of generally Cretaceous aspect may be 

 noted Haplopliragmium neocomianum and tfj>!rr>i>Iecta anceps. The 

 species which lend to the deposit an Upper Cretaceous appearance 

 .are Nodosaria zippei (a quite restricted form), N. snlcata (almost in- 

 variably Upper Cretaceous), Cristellaria /ii/nil/^ln, (_'. intermedia, and 

 C. secans. This latter species is in exactly the condition of growth and 

 size as found in the typical Chalk faunas of Europe, and is one of the 

 commonest species in the limestone from Need's Camp Lower Quarry. 

 All the rotalines, whilst having an extensive geological range, from the 

 Cretaceous to the present time, are typical of the Upper Cretaceous 

 also, and their present occurrence as to size and development favours 

 I he idea of their Cretaceous age. 



Of the Ostracoda only one species, Bairdia subdeltoidea, is available 

 for comparison, as the remainder are new forms. The examples 

 referred to the above-named specific form (a Cretaceous and early 

 Tertiary species) are those of typical Cretaceous valves.
