ART. 9 RECENT FOEAMINIFEEA CUSHMAN AND WICKENDEN 13 



Glohigerina dutertrei H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 



1884, pi. 81, figs. 1-3 (not d'Orbigny). 

 Glohigerina dubia H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 1884, 



pi. 79, figs. 17 a-c (not Egger). 



Test subglobose in the early stages, consisting of but four chambers 

 in each coil, closely grouped; aperture small and with a distinct lip; 

 in later stages with five or six chambers in a coil, the last coil usually 

 below the level of the others and with a distinct umbilicus. 



This is one of the commonest species in the Pacific and was first 

 described by Schwager from the Pliocene of Kar Nicobar. 



GLOHIGERINA INFLATA d'Orbigny 



Plate 5, figures 8 a-c 



Glohigerina inflata D'Orbigny, in Barker, Webb, and Berthelot, Hist. Nat. 

 lies Canaries, 1839, vol. 2, pt. 2 " Foraminiferes," p. 134, pi. 2, figs. 7-9.— 

 H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 1884, p. 601, pi. 79, 

 figs. 8-10. 



There are a few specimens of this species in the material, but not 

 as common as the preceding. 



GLOBIGERINA TRILOBA Reuss 



Plate 6, figures 1 a-c 



Glohigerina triloha Reuss, Denkschr. A"kad. Wiss. Wien, vol. 1, 1850, p. 374, 

 pi. 47, fig. 11. 



There are a very few specimens such as figured here in which the 

 final coil is made up almost entirely by three chambers, and may be 

 referred to Reuss's species, 



GLOBIGERINA species 



Plate 5, figures 7 a-c 



This very small form is interesting as it has a smooth young, later 



becoming spinose and the umbilical area covered by a thin platelike 



projection of the ventral side of the last-formed chamber. Rhumbler 



has figured similar forms in his Plankton Expedition Report, and 



they occur in the Upper Cretaceous. Not enough specimens were 



obtained to warrant a full description as these are evidently young 



specimens.
