See p. 106. Truncatulina dkpar, CO., and Tr. advcna, 

 D'O., are not distant allies, on the one hand ; and PI. umbo- 

 nella (Rss.), on the other hand, leads it into PL Ungcriaua.^ 

 All these are scarcely separable sub- 

 Tra'ietics, belonging to the ''clcgans" 

 group of Pidvlnulina repanda (F. 

 & M.). The mutual alliance and 

 gradational featui-es of these and 

 Pidv. Orbig>i?/i and Pulv. ornata 

 (Pvoemer, see above, p. lOt!), can 

 readily be seen on a comparison 

 )■ of the beautiful figures given by 

 Ecuss, and the less elaborate, but 

 recognizable, figures in Ecenier's 

 'iS^orddeutseh. Kreidegeb.' Prof. 

 Eeuss finds ^j)inulifirn the most 

 abundant form in the Gault of 

 Folkestone. His rdkxdata is almost 

 exactly the same as P. Pcrthclotiana 

 (D'O.).

 member of the " clcga-iis" group o( J'ulviiiu/ina.

§ YII. — In selecting the figured varieties oiPlanorlidinai,Pidvinu~ 

 lince, Discorhince, and Rotalice enumerated in the foregoing lists, as 

 examples of the known Cretaceous EoTALiNiE, we must not lose sight 

 of the other Eotahnes, such as Ccdcarina, Cymhcdopora, PateUina, 

 &o., in the Chalk and its associated strata. Of these, several in- 

 teresting species are known. "We must also explain that, besides 

 the figured species and varieties, there are in most cases many allied 

 forms enumerated in the respective memoirs, but not represented 

 there, having been previously figured. Fortunately several of the 

 forms noticed in the earlier memoirs have been refignred by our 

 German fellow-labourers, in the first style of modern litho- 

 graphy, and with real naturalistic art. In the appended Table we 

 have introduced, as far as we can recognize them, the other forms 

 referred to, besides those figured in the several memoirSj for the 

 different localities.

 Family EoTALns"^ (Carpenter) amongst a special fauna, correspond-
