AET.6 FORAMINIFEEA: POLYMORPHINIDAE— CUSHMANANDOZAWA 85 



a Cretaceous form corresponding to Tertiary Globulina rotundata, 

 which has almost the same featm'es. 



GLOBULINA CONSOBKINA (Fornasini)

Polymorphina sororia Rbuss var. consobrina Fornasini, Mem. Istit. Bologna 

 Accad. Sci., ser. 5, vol. 18, 1900-1902, p. 69, fig. 21 (in text). 



Test typically fusiform, pointed at both extremities; chambers 

 rounded, arranged in an almost triserial series; sutures depressed but 

 little, distinct; wall smooth; aperture radiate. 



Length 0.60-1.25 mm.; breadth 0.45-0.90 mm.; thickness 0.30- 

 0.60 mm. 



Globulina consobrina is closel^v related to Globulina rotundata, but 

 its initial end is acuminate. 



Distribution. — Rather common in European young Tertiary de- 

 posits. Fornasini's figured specimen was obtained from the Plio- 

 cene of Siena. We have specimens from the following locaUties : 



Miocene. — Hungary, Tortonian, Varpolata. Austria, Tortonian, 

 Amphistegina marl, Grunes Kreuz, Nussdorf, Vienna. France. 

 St. Avit, near Mont de Marsan, Helvetian, Moulin de Minoy, Salles; 

 Burdigalien inferieur, Moulin de TEglise, Saucats.

Soc, 1890, p. 561, pL 11, fig. 13. 



Test ovate to oval, more or less compressed, rounded at the base; 

 chambers rather elongated, embracing, arranged in a nearly over- 

 lapping, triserial series; sutures not depressed, generally distinct; 

 wall smooth, often with fistulose tubes; aperture radiate. 



Length 0.45-0.70 mm.; breadth 0.25-0.50 mm. ; thickness 0.18-0.38 

 mm. 



In 1856 Eeuss described three species of compressed and o al 

 Globulina from the German Oligocene. They are Polymorphina 

 munsteri, P. amygdaloides, and P. ovulum, of which the second is the
