FAMILY 43. RUPERTIIDAE 331 



Genus CARPENTERIA Gray, 1858 

 Plate 52, figures 14-17 

 Genoholotype, Carpenteria halaniformis Gray 

 Carpenteria Gray, Proc. Zool. Soc. London, vol. 26, 1858, p. 269. 

 Dujardinia Gray, 1. c, p. 270 (genoholotype, Dujardinia mediterranea 



Gray). 

 Polytrema (part) Carter, 1876 (not Risso). 



Test attached, early chambers trochoid, later spreading out 

 over the surface of attachment but with the inner ends piled up 

 in a loose spire or the whole test becoming subcylindrical, the 

 chambers loosely spiral or even uniserial; wall calcareous, 

 coarsely perforate; aperture in the young narrow, in the older 

 stages somewhat rounded at the end of a tubular projection, and 

 in the uniserial forms sometimes with a tubular neck. 



Cretaceous to Recent. 



Genus EORUPERTIA Yabe and Hanzawa, 1927 



Plate 52, figures 18-20 

 Genoholotype, Uhligina boninensis Yabe and Hanzawa 

 Eorupertia Yabe and Hanzawa, in Cushman, Contr. Cushman Lab. 



Foram. Res., vol. 3, 1927, p. 97. 

 Uhligina Yabe and Hanzawa, Japanese Journ. Geol. Geog., vol. 1, 1922, 

 p. 71 (genoholotype, Uhligina boninensis Yabe and Hanzawa) (not 

 Uhligina Schubert). 



Test with the early stages coiled, later in a subcyclindrical 

 form, the chambers in an elongate spiral about a hollow center; 

 wall calcareous, coarsely perforate, developing canals and 

 pillars; aperture not well distinguished. 



Eocene. Japan. 



The genera of this family are all attached forms growing up- 

 ward from the base, coarsely perforate and with the aperture 

 tending to become terminal. Rzehak has considered that Karreria 

 Rzehak, 1895 and Semseya Franzenau, 1893, should be grouped 

 near Carpenteria, but without seeing the types it is very difficult 

 to place these.
