70 PROCEEDINGS OF THE NATIONAL MUSEUM vol.77 



Variety ornamented with small spines or punctations (not de- 

 pressions, as described by d'Orbigny). 



The original specimen in Paris is lost. Paratype specimens pre- 

 served in the geological department, Museum of Natural History in 

 Vienna, are mostly Orbulina universa with a few Globulina gibba (some 

 fistulose forms) and one specimen somewhat resembling the figure 

 of Globulina punctata given by d'Orbigny. This is slightly elongated, 

 just like a specimen in our collection from the Tortonian clay of 

 Baden in the Vienna Basin. Brady, Parker, and Jones regarded 

 Globulina punctata as representing a thin-walled condition in a shell 

 of the common type of Globulina gibba, but the minute depressions 

 on the surface noted by d'Orbigny are not depressions and do not 

 represent the minute foramina in the chamber wall, but are surface 

 ornamentations. Brady, Parker, and Jones separated the forms 

 beset with fine spines as a distinct species, Polymorphina hirsuta, but 

 such forms grade into typical variety punctata, and we think it is 

 unnecessary to separate them. 



Length 0.35-0.65 mm.; breadth 0.30-0.55 mm.; thickness 0.30-0.55 

 mm. 



D'Orbigny 's Globulina rugosa, described as having a globular test 

 marked by longitudinally arranged depressions, was considered by 

 several authors to be the same as Polymorphina (not Globulina) 

 rugosa, having a peculiar test beset with spines, but there is no data 

 whether d'Orbigny considered them as synonyms. The original 

 specimens of these two species are lost, but paratype specimens of 

 Globulina rugosa are in the Museum in Vienna and were examined 

 by Ozawa. They are mostly Globulina gibba with one Orbulina 

 universa, and there is nothing like the form figured by d'Orbigny. 



If the specimen has the feature as illustrated by d'Orbigny and 

 characterized by small depressions arranged longitudinally, then 

 Globulina rugosa is considered to be nothing but Globulina punctata. 

 In the middle Miocene (Tortonian) clay in the Vienna Basin Ozawa 

 collected some Globulina ornamented with broken but strong costae, 

 which resemble Globulina myristiformis Williamson. They appear 

 to be Globulina rugosa, but there is no original specimen, and the 

 paratype specimens are ail quite different from the figure, therefore 

 it is more advisable to place Globulina rugosa as a synonym of Globu- 

 lina gibba var. punctata d'Orbigny.
