Family 43. RUPERTIIDAE 



Test in the early stages, trochoid, attached by the dorsal side as in 

 Cihicides, later extending upward from the base of attachment still 

 keeping a loose spiral; wall calcareous, coarsely perforate; aperture 

 either at the inner margin of the chamber or becoming terminal and 

 rounded, often with a neck and lip. 



There are but three genera in this family, Rupertia known from the 

 Tertiary and the present oceans, Carpenteria ranging from the Cre- 

 taceous to Recent, and Eorupertia known only from the Eocene of 

 Japan. They form a specialized group evidently derived from the 

 Anomalinidae from such forms as Cibicide^ by an upward extension 

 of the later chambers, the general spiral character kept in most 

 species, but in some species of Carpenteria becoming very irregular 

 and almost uniserial.

Genoholotype. — Rupertia stabilis Wallich. 



Test attached, in the young, trochoid, the chambers later extending 

 upward from the base of attachment still keeping a loose spiral ; wall 

 calcareous, thick, coarsely perforate; aperture in the early stages 

 narrow, at the base of the chamber, in later development becoming 

 much more open, rounded, and with a thickened, rounded lip. 



This genus is represented in the Atlantic by the single species which 

 follows.
