152 THE FOEAMINIFEEA 



Genus Carterina, Beady. 



Test rotaliform, convex ; normally adherent ; 

 with pointed oval calcareous spicules formed by the 

 organism itself. Recent. 



Example. — C. sjnculotesta, Carter sp. (Rotalia), 

 'Ann. and Mag. Nat. Hist.' ser. 4, vol. xx. 1877, 

 p. 470, pi. xvi. 



This singular little organism is peculiar in 

 being constructed of little spicular bodies secreted by 

 the sarcode ; they are arranged somewhat regularly, 

 with their long axes in the direction of the peripherical 

 margin of the test. The central portion of the test 

 is usually a dark purplish brown, the outer chambers 

 gradually fading off to white. 



Carter's specimens came from the South Pacific 

 and the Gulf of Manaar ; Brady records it from the 

 Gulf of Suez at 40 fathoms, and Millett from the 

 Malay Archipelago. 



Eecently the writer has obtained the same 

 species from the dredgings at Funafuti, where it 

 occurs outside the reef at 36, 50, and 60 fathoms, and 

 in the lagoon at 19, 20, 25, and 26 fathoms, usually 

 attached to Halimeda fronds. Beceut. (Plate 8, 

 figs.F,/.) 



Genus Webbina, D'Okbigny. 



Test adherent ; consisting either of a single tent- 

 like chamber or of a number of such chambers 

 connected by adherent stoloniferous tubes. It is 

 isomorphous with the hyaline form Vitrnvebbina.
