The uppermost bed of Vicarya) at one foot below the base of 

 the Lower Greensand, contains a Cyprid, not previously noticed, 

 and now described by Prof. Rupert Jones as Cypris corniyera 

 (Fig. 6, 1). In the same pieces of shale with it there occur 

 Metacypris Fittoni, and fish-bones.* Another new ostracod, 

 described by Prof Rupert Jones {pp. cit.) under the name Candona 

 Mantelli (Fig. 6, 2), occurs at 80-84 feet below the Perna Bed 

 in the cliff between k^hepherd's Chine and Atherfield Point. It 

 is associated with Metacypris Fittoni (Mantell), small ; Cypridea 

 spinigera (Sow.), young individuals ; Cypridea tuherculata (Sow.) ; 

 Cypridea valdensis (Fitton) ; Cyrena ; and Paludina.
