AET. 6 FOEAMINIFERA: FOLYMORPHINIDAE- — CUSHMAN AND OZAWA Ol 

 GLOBULINA FLEXA Cushman and Ozawa, new species 



Plate 20, figures 1 a-c 



Test longer than broad, greatest width above the middle, sides not 

 equally convex, base broad but tending to become pointed at the 

 middle, round in transverse section; chambers few, extending well 

 toward the base; sutures distinct, doublj^ curved in a sigmoid man- 

 ner, the upper part convex, the basal portion concave; wall smooth, 

 translucent; aperture ra,diate, somewhat extended. 



Length 0.60-0.70 mm.; breadth 0.32-0.37 mm.; thickness 0.25- 

 0.30 mm. 



Holotype. — (Cushman Coll. No. 11,587.) From upper Oligocene, 

 Doberg, near Biinde, Germany. 



The elongate test and the doubly curved sutures in a sigmoid man- 

 ner are very characteristic of the species, and there is little danger of 

 confusing Glohulina jiexa with any other species or varieties of Glohu- 

 lina. The nearest species is Glohulina ampulla, having a broadly 

 rounded base pointed at the middle as in the present species, but 

 Glohulina jiexa has a longer test with sigmoid, curved sutures. 



Soldani's Polymorphium pyriformium, compared by d'Orbigny with 

 his Pyrulina gutta, has an elongate test, and its sutures are curved in 

 a sigmoidal manner and is probably identical with the present species. 



Distrihution. — We have specimens of this striking and beautiful 

 foraminifer from the upper Oligocene of Ahnatal, near Cassel, Ger- 

 many. A very similar form occurs in Recent material from Dogs 

 Bay, Ireland.

Test oval, rounded at the initial end, more or less acute toward the 

 aperture, nearly circular in end view; chambers few, arranged in an 

 almost triserial series, the last-formed one generally much removed 

 from the base; sutures not depressed, often indistinct; wall fairly 

 thick, ornamented by numerous fine longitudinal costae not greatly 

 raised, independent of the sutures and close together; aperture broad, 

 radiate, slightly produced. 



Length, 0.50-0.65 mm.; breadth, 0.30-0.42 mm.; thickness, 0.30- 

 0.40 mm.
