APPENDIX 



The following Tabic exiiibits the names assigned by Messr.s. Parker and Rupert Jones to tlic speeies 

 and varieties described and figured in Professor Williamson's ' ^Monograph on the Recent Foraminiferu 

 of Great Britain.' This nomenclature is founded on the principles set forth by those authors in their 

 successive memoirs "On the Nomenclature of the Foraminifera" in the 'Annals of Natural Historv,' and 

 adopted, with some modifications, in the present work. Their rule has been to retain the qjccijic names 

 assigned by the systematist by whom the type was first properly designated. Hence some of the names 

 ol' types and varieties which liavc since been differently designated, are those assigned by D'Orbigny in 

 his first memoir ('Ann. des Sci. Nat.,' torn, vii) to the forms delineated by Soldani, whose figiu'cs have 

 been carefidly collated. Another reason why some altered names appear, is because Messrs. Parker and 

 Rupert Jones have been led by the wider range of their studies to adopt in several instances a different 

 style of type from tliat furnished by the simple forms of the British Fauna surveyed by Professor 

 Williamson; their aim having been to adopt those forms iis types of speeies, which give a fair repre- 

 sentation of all or neai'ly all the characters that seem properly to belong to each.
