The above synonymy is given in order that the claim of Patellina 

 as the name of the genus may be readily seen. The subject of the 

 nomenclature has already been discussed by Carpenter, Parker, & 

 Jones," and, later, by Professor Eupert Jones.^ 



It will perhaps be useful to point out briefly the shortcomings 

 of the various names earlier than Patellina. 



Orhitolites is now retained for one of the two types originally 

 confused under the same name. 



Madreporites does not stand according to the Strickland Pule 

 No. 11, since it implies a false relationship; moreover, the name 

 was previously used by Deluc (1802) in connection with Orhitolites. 



Orhidites, an improved form of Orhitolites, was used by Lamarck 

 vphen describing specimens belonging to that and the present genus. 



Cyclolina used to denote a depressed, complanate form, probably 

 of the present genus, but by no means typical. 



Orhitolina appears to have been originally used in the sense of 

 a recent form of Orhitolites, which was at the time thought to be 

 a fossil genus, the terminations ina and ites being used by Lamarck 

 and others for recent and fossil specimens respectively. This 

 generic term has been largely used on the Continent to designate 

 the Patellince with large tests and thick shell-walls, and which are 

 so common in various Cretaceous beds in France, Spain, and 

 Switzerland. Should these particular forms be proved to possess 

 hyaline or tubulated shell-structure, there is no ground for retaining 

 the name even as an isomorphic arenaceous group Avith Patellina. 



Orhitulites is evidently a misspelling.
