 Moellerina Eimer and Fickert, Zeitschr. Wiss. Zool., vol. 65, 1899, p. 677 



(genotype, by designation, Cribrostoviwm gracile Moller). 



Test composed of chambers biserially arranged; wall finely 

 arenaceous, perforate; apertures in the early portion as in 

 Textularia, later becoming multiple and with a cribrate terminal 

 face to the chamber. 



Carboniferous to Permian. 



Genus CLIMACAMMINA H. B. Brady, 1876 



Plate 11, figures 17, 18; plate 13, figure 7 



Genoholotype, Climacammina antiqua H. B. Brady 



Climacmnmina H. B. Brady, Pal. Soc. Mon., vol. 30, 1876, p. 67. 

 Moellerina Eimer and Fickert (not Schellwien), Zeitschr. Wiss. Zool., 

 vol. 65, 1899, p. 605. 



Test in the early stages composed of chambers biserially ar- 

 ranged, later becoming uniserial; wall finely arenaceous and 

 perforate; aperture in the early stages simple as in Textularia, 

 then becoming cribrate in the adult. 



Carboniferous to Permian. Tertiary and Recent ( ?) . 



The "Bigenerina robusta H. B. Brady" (Rep. Voy. Challenger, 

 Zoology, vol. 9, 1884, p. 371, pi. 45, figs, 9-16) and some Tertiary 

 species have essentially the characters of Climacammina, but 

 there seems to be a very wide gap where no representatives of 

 the genus are known if these are the same as the Palaeozoic 

 forms.
