TROPICAL PACIFIC FORAMINIFERA OF ALBATROSS 13 



TEXTULARIA CONCAVA Karrcr 



Plate 3, Figures 6 a, b 



Many forms have been referred to this species described by Karrer 

 from the Miocene of Europe. Some of the specimens figured from 

 the Mediterranean are very close to Karrer's original figure, and 

 also some Recent Indo-Pacific shallow water specimens. The only 

 specimen in the present collection that can be referred to Karrer's 

 species is that figured, which is from Albatross Station 113815, 

 latitude 15° 15' 15" S., longitude 147° 51' 35" W., in 524 fathoms 



Family VERNEUILINIDAE 



Genus GAUDRYINA d'Orbigny, 1839

 eres," p. 109, 1839. — Cushman, Cushrnan Lab. Foram. Res. Spec. Publ. 

 No. 1, p. 126, 1928. 



Genotype. — By designation, Gaudryina rugosa d'Orbigny. 



Test in the early stages triserial, later biserial, transverse section 

 angled or rounded; wall coarsely or finely arenaceous often with a 

 large proportion of cement; aperture, typically a low opening at 

 the base of the inner margin of the chamber, or in the wall of the 

 apertural face. Lower Cretaceous to Recent. 



There are a number of species in this Pacific material, and these 

 show very little difference in the relative amount of the test made 

 up by the triserial portion. As already noted under Spiroplectam- 

 mina, textularian forms may easily be developed from Gaudryina 

 and the triserial portion entirely crowded out. All stages in this 

 process can be seen in various species of the genus.
