12. Glohigerina canaliculata Eeuss sp. 



13. Trujicatulina scJilanhachi Eeuss sp. 



14. Pulvinulina elegans d'Orb. sp. 



15. P. carpenteri Eeuss sp. 



16. P. reticulata Eeuss sp. 



17. P. -pondensis sp. nov. 



18. Botaiia soldanii d'Orb. sp., var. 7iitida Eeuss. 



Of the fifteen species already described, two are from the Lower 

 Cretaceous (Neocomian) or older formations, viz., Haplopliragmiuni 

 neocomianum and Vaginulina intumcscens. Three appear to be 

 restricted to the Albian stage, viz., Vaginulina Immilis, Pulvinulina 

 reticulata, and P. carpenteri. Five range from the Gault to the 

 Upper Chalk, viz., Pleurostomella suhnodosa, Nodosaria prismatica, 

 N. zippei, Truncatulina schlcenbaclii, and Rotalia soldanii va.r. nitida. 

 The remaining five species have a still wider range, and extend into 

 the Tertiary formations. 



The species are all such as would be found in quite shallow water. 



The valves of the Ostracoda are as a rule somewhat thin and 

 fragile, but are well preserved as regards their superficial ornament. 



Six species and varieties were found, two of which are new. 



They are as follows : — 



1, Macrocypris simplex Chapman. 



'1. Bytliocypris simidata Jones sp. 



3. Cythere ? drupacca Jones. 



■4. Cythcrcis ornatissima Eeuss sp., var. reticulata J. &. H. 



5. CytJieridea longicaudata sp. nov. 



6. Cythcropteron elongato-concentricum sp. nov. 



7. Cytherclla ivilliamsoniana Jones. 



Of the above seven species of Ostracoda one doubtful form is of 

 Oolitic age, viz., Cythere drupacea, two range from the Neocomian 

 to the Upper Chalk, viz., Cythcrcis ornatissima var. reticulata, and 

 Cytherclla unllicunsoniana. One species has occurred in a rcmanic 

 bed of the Albian, viz., Macrocypris simplex; and one species 

 appears to range throughout the Chalk formation, viz., Bythocypris 

 simulata. 



The general facies of the present series of Microzoa would lead 

 one to conclude their position to be intermediate between the Lower 

 and Upper Cretaceous series, but having a stronger affinity towards 

 the latter group.
